Introduction to the MobileMapper Pro System

The MobileMapper Pro system from Magellan is composed of two main elements: the MobileMapper Pro receiver and Mo- bileMapper Office software running on a PC-type computer.

The MobileMapper Pro receiver is a handheld navigation and positioning device that enables you to describe the features being mapped and then format the data so that later it can be uploaded to a GIS. It offers an easy-to-use and easy-to-deploy solution for general mapping and for asset management.

MobileMapper Pro combines all the navigation capabilities of a recreational handheld with feature attributing software to support GIS data collection in the field.

The MobileMapper Pro receiver and its main functions are fully described in this manual.

MobileMapper Office is an office software suite that interfaces the MobileMapper Pro receiver with your GIS system. Mo- bileMapper Office allows you to prepare GIS jobs, feature libraries and waypoint files, build background maps from GIS data files and manage the information logged in the field (upload/download functions).

The MobileMapper Office software, its main functions and functions relative to data exchange between MobileMapper Pro and MobileMapper Office are described in a separate manual (Mobile Mapper Office User Manual P/N 631514).

Finally, the Appendices section in this manual covers a number of topics such as product specifications, SD card installation, connectors & cables and glossary of terms used.

Please note that a printed Getting Started Guide is included in your MobileMapper Pro system. This short, multilingual guide, which is presented in a tutorial form, is intended to help you complete your first job. Practising with this guide will allow you to understand the essentials of the system.

The scrolling button has three different functions:

• It is used to move the cursor in the chosen

direction, from a data

field to another, from

an option in a menu to

the previous or next

option.

• In a highlighted field,

the left/right arrow

moves the cursor back-

ward/forward; The up/

down arrow incre-

ments/decrements the

highlighted figure or

string.

• On the Map screen, a

navigation screen, this

button allows you to

switch to cursor mode

and then to move the

cursor in ALL direc-

tions, not only the left,

right, up and down

directions.

External antenna input:

Located on the right-

hand side of the

receiver, under a flap

in the black rubber

bumper, near the top of

the display. Peel the

flap up from the bot-

tom to reveal the exter-

nal antenna input

(SMB-f connector).

SD Card

MobileMapper Pro

ships with a 16-MB SD

card, but you can use

SD cards up to 128

MB (maximum recom-

mended size). 64-MB

cards offer the best

combination of high

performance and high

memory.

Battery Life

You can expect up to

16 operating hours

from 2 Li-ion AA bat-

teries with the back-

light turned off. Using

the backlight will

shorten the battery life

significantly. With the

backlight on continuously, you can expect

about up to 8 hours of

usage from the two Li-

ion batteries that came

with your MobileMap-

per Pro.

Installing the SD Card and the Batteries

- Slide the two tabs on the back of the receiver to the left and remove the battery compartment door.

- Hold the SD card with 2 fingers with the label facing you.

- Place the top of the SD card in the channel provided in the battery compartment.

- Carefully push the SD card towards the top of the unit until you feel it lock into place. Do not force the SD card.

- Insert the two batteries according to the diagram inside the receiver. Be sure to observe the proper polarity.

SD Card

- Reinstall the battery compartment door making sure to slide the tabs to the right to ensure a watertight seal.

Note: You may see a gap between the battery compartment door and the receiver. This is normal and does nto mean your receiver is not waterproof. The waterproof gasket is on the receiver around the battery compartment and not around the edge of the compartment door.

Page 13

The very first time you

use your MobileMapper

Pro, or after erasing all the data from memory,

the Power-On proce-

dure is longer than described here because the unit having no posi-

tion in memory, initial-

ization is needed to

help the unit track sat-

ellites (see 1st-time

use on page 8).

Power Down Screen

Turning Power On/Off

In the Power-On procedure described below, it is assumed that the receiver has already been used in a working session and so position data is available from the former working session to help MobileMapper Pro compute its position.

• To turn the unit on, press the PWR button. The Start-up screen appears, followed by the Database Copyright screen and the Agreement screen. After accepting the warning information, the last navigation screen you were viewing at the end of the last session will be displayed. If the last navigation screen view was the Map screen, the last zoom scale setting will be used.

• To turn the unit off, press the PWR button. The Power Down screen is displayed.

Doing nothing will turn off the unit at the end of the countdown sequence. Pressing the PWR button again will turn off the unit immediately. Pressing ESC will cancel the Power Down sequence.

NOTE: It is important to close any open feature and any open job BEFORE turning the power off or switching to or from an external source of power.

If the receiver automatically shuts down due to low power while recording a job, it is best to open a new job after replacing the batteries rather than appending more data to the previously open job that was automatically closed by the receiver. You can easily merge both jobs in MobileMapper Office after download.

Page 14

To prevent accidentally turning the backlight on and leaving it

on, the unit will turn

the backlight off when

no buttons have been

pressed for 4 minutes.

Pressing any button will turn the backlight

back on in this

instance. You can

change the time delay

for the backlight using

the Light Timer option

in the Setup menu (see

page 68).

Setting the Screen Backlight

The screen backlight can be set to one of three levels (low, high or off). At power on, the screen backlight is set to high level. Follow the sequence below to choose another level:

- Hold down the PWR button for 2 seconds : Backlight drops down to low level

- Hold down the PWR button again for 2 seconds: Backlight turns off.

- Hold down the PWR button again for 2 seconds: Backlight comes back to high-level illumination.

Using the backlight makes the screen display easier to see, but it also requires more power. The less you use the backlight, the longer your batteries will last.

Setting the Units

To change the units that MobileMapper Pro will use:

- Press MENU. Use the up/down arrows to highlight Setup and press ENTER

- Use the up/down arrows to highlight Units and press ENTER.

- Use the up/down arrows to highlight the set of units you want and press ENTER. Press ESC to return to the last screen viewed

Units Screen

Page 15

Holding the unit

You can observe the

signal strength and the

satellites being used on

the Satellite Status

screen (see page 8).

Getting a Position Fix

The unit is designed to fit comfortably in your hand. Hold the MobileMapper Pro in the palm of your hand with the top end of the receiver pointing towards the sky.

MobileMapper Pro's internal antenna, located in the top end of the receiver, needs to have a relatively unobstructed view of the sky. This allows the unit to receive signals from all the satellites currently available.

If the view of the sky is poor due to buildings, heavy foliage or other obstructions, the satellite signals can be blocked and the receiver may take longer to compute a position fix.

Your receiver will have the best view of the sky when you hold it at eye level. You should also hold your receiver vertically. This allows the internal antenna to function optimally for the best accuracy. This is especially important when collecting data for post-processing (unless you use an externa antenna).

Page 16

Skipping Initialization

You can skip the initial-

ization process by

pressing the NAV key

anytime after selecting

the language you want

MobileMapper Pro to

use and accepting the

agreement. If

MobileMapper Pro is

able to collect satellite

data (i.e., have a clear

view of the sky) it will

begin to self-initialize.

It could take anywhere

from 3 to 14 minutes

to compute its posi-

tion, depending on how

many weeks have

elapsed since it was

last used.

Initialization for First-Time Use

MobileMapper Pro’s software will walk you through the process of setting up the receiver for first time use. This procedure is commonly referred to as “Initializing the Receiver.” The purpose of this initialization is to provide MobileMapper Pro with a general knowledge of its approximate location.

It may seem a little confusing that a device that is supposed to compute its own position must first be told where it is. The truth is that the receiver does not need to be told where it is, but selecting an approximate location the first time will allow the receiver to compute its position more quickly. You do not have to type in coordinates because the software will let you select a geographic location that is closest to your country, state or province. Once you do this, a file preloaded into the receiver during manufacture - called an almanac - will tell the receiver which GPS satellies are currently orbiting overhead. The receiver then looks only for these satellites when calculating its first location.

Under normal use, MobileMapper Pro will save the last position it calculated and use it the next time it is turned on to quickly estabish a first fix. In most cases, therefore, MobileMapper Pro does not need to be initialized when it is turned back on. However, you should initialize your receiver when it is new, has not been used for several months, has been moved several hundred kilometers since its last fix or when you have cleared its memory (such as when you upload a new version of software).

Start-up, Copyright &

Language Screens

Follow these instructions to initialize MobileMapper Pro:

1. Turn MobileMapper Pro on by pressing the PWR button. The unit turns on and displays the startup screen, followed by the Database Copyright screen and the language selection screen.

2. Select your language using the up/down arrow to move the cursor to this language. With the desired language highlighted, press the ENTER button.

Page 17

Agreement screen

Region & Area Screens

The GIS data capture and navigation software in MobileMapper Pro are available in Dutch, English, French, German, Lithuanian, Polish and Spanish. Support for the navigation software alone is available for Italian, Portuguese and Swedish. Separate versions of the MobileMapper Pro software are available in Russian and Chinese.

3. The “Agreement” screen is then displayed for about 10 seconds. If you understand and agree to the statement presented, press ENTER before the 10 seconds have elapsed (or the unit will shut off). A message box is then displayed indicating that the unit needs to be initialized.

4. Press ENTER. The unit asks you to select your region and area. Use the up/down arrows to highlight your general region and press ENTER. Again, use the up/down arrows to highlight your area and press ENTER.

5. The cursor appears in the Time field, waiting for you to input your local time. Please enter the time in 0-12 hr. format, not in 0-24 hr. format. Set your local time using the arrow keys as follows: use the up arrow to increment the highlighted figure, or the down arrow to decrement it. Then press the right arrow to highlight the next figure. Set this figure now using the up or down arrow, etc. Be sure that you set the AM/PM indicator. When the time is correct, press ENTER.

Time & Date Screens

The last piece of information needed is the date. As above, using the arrow keys, enter the present date and then press ENTER.

All the information that the unit needs to speed up the process of computing its first fix has been entered and the Done field is highlighted.

Page 18

Satellite Signal Strength Chart:

Clear bars indicate that

the unit is starting to

get information from

satellites. Solid bars

indicate that the satel-

lites are being used to

compute your position.

Satellite Position Graph:

The 2 circles indicate

satellite elevation as

seen from your current

position. The outer cir-

cle represents the hori-

zon and the inner circle

represents 45° from

the horizon. The cen-

ter of the circle is 90°

from the horizon, or

directly overhead.

6. To complete the initialization process, press ENTER again. The Satellite Status screen is displayed and MobileMapper Pro begins acquiring the data from satellites.

Watching the bars appear and turn solid on the screen, you can progressively see the unit lock onto satellites.

GIS Data Logging Functions

Feature Libraries

Feature libraries contain lists of features that you should be visiting during your field sessions.

Features are four types:

- Point feature: The geometrical representation of this feature is a point. Logging this type of feature requires static occupation at the point.

- Line feature: The geometrical representation of this feature is a line. Logging this type of feature requires that you move along this line.

- Area feature: The geometrical representation of this feature is an area. Logging this type of feature requires that you move along its contour or you make several static occupations if it is a regular area (with straight sides).

- Grid feature: The geometrical representation of this feature is an array of evenly-distributed waypoints. MobileMapper Pro will guide you to each of these waypoints where you should enter a measurement performed at this point.

Each feature also has a number of attributes. There are three categories of attributes:

- Menu style where the attribute values are words or phrases that you pick off a list (e.g. a list of values for the attribute Condition might include Good, Needs Repair, etc.; see opposite)

- Numeric style where you select a number within a specified range (e.g. the # of bulbs might be in the range 0 to

- Text style where you type in a note that can contain both numbers and letters (e.g. the closest street address)

You can upload as many feature libraries as you want into MobileMapper Pro. Just remember that you can use only one feature library for logging data to an individual job.

Logging New GPS/GIS Data

Prior to starting logging GIS data, be sure MobileMapper Pro is computing your position when you stand near the first feature you want to log. For the best accuracy it is important to hold the receiver vertical and at eye level so it has a clear “view” of the sky.

Press NAV until you display the Map screen. If an arrow is displayed at the center of the Map screen and you can see that your position on the screen is the expected one, then you can start your job. (An hour-glass icon indicates that no position has been calculated yet.) Follow the instructions below to log GIS features.

1. Creating a Job and Selecting a Feature Library

- Press the LOG button

- Select the Create New Job option and press ENTER. The screen displays the Job Name field in which you should enter the name of the new job. A keyboard is displayed underneath to let you enter this name.

To use the keyboard, press the arrow keys to move the cursor over the keyboard. For example, if the job name is “JB010”, highlight “J” using the arrow keys and press ENTER. Then select “B” and press ENTER, etc.

- When you have finished entering the name, highlight the OK key on the screen and press ENTER. A new screen is then displayed listing the feature libraries stored in MobileMapper Pro.

- Use the down/up arrow to highlight the library you want to work from and press ENTER. The screen now lists all the features available from the selected feature library.

IMPORTANT! If the “post-processing” option has been enabled in the receiver, an additional screen will appear between the feature library screen and the features list screen. This new screen will ask you to choose the job mode. For more information, see page

33.

MobileMapper Pro uses a fixed, time-based logging interval (1 second)

when you log a point

feature. The logging

interval parameter can-

not be accessed when

you log a point feature.

Logging screen

The Logging screen

also displays the time

elapsed since you

started logging at this

point feature, the num-

ber of satellites cur-

rently received and the

current value of PDOP

(see also page 28).

If you start logging a

new feature and you

realize you this is a

mistake, then you can delete the new feature being logged by press-

ing MENU and select-

ing Delete <feature

name>.

Deleting features only

applies to new fea-

tures being logged, not

to features already

logged.

2. Logging and Describing a Point Feature

- Choose the type of feature you want to log from this list. You can tell by the name of this feature whether it is a point feature, a line feature or an area feature.

- Highlight a point feature (you are supposed to be near one of these features) and press ENTER. This starts feature logging.

The Logging screen is now displayed where you can see the list of attributes pertaining to this feature. You will now enter the “Description” phase of the feature

- With the first attribute highlighted, press ENTER and choose the right attribute value describing the feature near you and press ENTER. This takes you back to the Logging screen.

- Highlight the next attribute in the list and repeat the previous step. Repeat this step until all the attributes have been properly described.

“Describing” the feature only takes a few seconds. By the time you are done with the feature description, the feature’s GPS position will probably have been saved in the job. You can also stay more time on the feature to let the receiver determine several positions. This will give an even more accurate position for the feature as MobileMapper Pro will average all the GPS positions it has computed on the feature.

- To stop logging the feature, on the Logging screen, use the down arrow to highlight the Close field and press ENTER. This takes you back to the Feature List screen

- Move to the next feature and resume the above instructions to log this feature.

Page 22

Note: There is a

spreadsheet calculator

on the Magellan Tech-

nical Support ftp site

(ftp://ftp.magel-

langps.com,

MobileMapper/FAQs

directory) that you can

use to estimate how

long you can log data

based on how much

free memory is on your

receiver's SD card and

which logging interval

you wish to use.

3. Logging and Describing a Line Feature Basically, you use the same procedure as when you log a

point feature (see 2. above). There are however two differences when you log a line feature:

- You need to define a logging interval when you start logging the feature

- And then you are supposed to move from the beginning to the end of the line feature before stopping the logging.

These differences are explained below. After highlighting a line feature from the Feature List

screen (for example a road) and pressing ENTER, MobileMapper Pro starts logging GPS positions from the position where you are. The default logging interval is 5 seconds.

By decreasing the logging interval you can increase the level of detail in your maps. By increasing the logging interval, you can save memory. In general, you should set the logging interval to the smallest setting possible without running out of memory (see note opposite). Remember you can take multiple SD cards with you to the field. The only requirement is that you close a job file before powering down the receiver to replace the SD card.

To change this interval:

- Press MENU, highlight Logging Interval and press ENTER.

Selecting the logging

interval option

Page 23

Logging screen

The Logging screen

also displays the dis-

tance traveled since

you started logging the

line feature, the num-

ber of satellites cur-

rently received and the

current value of PDOP

(see also page 28).

Two options are then prompted: By Time: Select this option when you want to log a new

GPS position at regular intervals of time regardless of the distance traveled since the last position logged. After highlighting this option, press ENTER, choose a time interval from the list and press ENTER. This takes you back to the Logging screen where you can see the list of attributes pertaining to the feature. By Distance: Select this option when you want to log a new GPS position only after you have moved by a certain distance since the last position logged. After highlighting this option, press ENTER, choose a distance interval from the list and press ENTER. This takes you back to the Logging screen where you can see the list of attributes pertaining to the feature.

- As with a point feature, describe the feature by describing the different attributes pertaining to the feature

- When the description is finished, you can start walking along the line feature

- When you arrive at the end of the line feature, with MobileMapper Pro still displaying the Logging screen, highlight the Close field at the bottom of the screen and press ENTER to stop logging the feature.

The receiver determines the length of a line feature by estimating the distance between successive points on the line feature with the assumption that each point is on a sphere of average Earth radius. The elevations of the points are not factored into the equation. Thus the receiver calculates the spherical distance rather than the horizontal or slope distance between the successive positions.

Page 24

Logging screen

This screen displays

the current values of

perimeter and area

measured since you

started logging the fea-

ture (+ number of sat-

ellites and PDOP)

If you wish to change the logging interval while you are logging a line feature, you first need to pause the logging of the feature:

- Press MENU, highlight Pause <line feature name> and

press ENTER

- Press MENU again, highlight Logging Interval, press

ENTER and set the new logging interval as explained above.

- After changing the logging interval, press MENU, high-

light Resume <line feature name> and press ENTER. The receiver will continue to log the feature, but this time according to the new logging interval.

4. Logging and Describing an Area Feature Basically, you use the same procedure as when you log a line feature, especially regarding the need for defining a

logging interval (see 3. above). The only difference between a line and area feature is that for an area feature, the first and last position calculated by the receiver are connected when you close the feature.

Record the attributes of an area feature as you do for a line feature (see page 14):

- Select the name of the area feature from the list of features and press ENTER. MobileMapper Pro starts logging the area feature.

- Choose a time-based logging interval (see explanations given for a line area on page 15). This takes you back to the Logging screen where the list of attributes for the feature is displayed

- Describe each attribute by selecting or entering the appropriate attribute value for each of them.

Page 25

Selecting the Pause

Park option

The receiver determines the perimeter of an area feature by estimating the distance between successive points on the line feature with the assumption that each point is on a sphere of average Earth radius. The elevations of the points are not factored into the equation. Thus the receiver calculates the spherical distance rather than the horizontal or slope distance between the successive positions. The perimeter of the area feature is the sum of all these distances. For the same reason, the measured area is that of a curved, not flat, feature.

5. Pausing a Feature When you are recording lines or areas, it is sometimes

impossible to walk or drive the entire length of the feature because of obstacles in your way such as fences, buildings, bodies of water, etc. When you must interrupt the recording of any feature (excluding point features), follow these steps:

- Press MENU, highlight Pause <feature name> and press

ENTER. This pauses the logging of the feature.

- Move around the obstacle to the next accessible portion of the feature

- To resume logging, press MENU, highlight Resume <feature name> and press ENTER. This resumes the logging.

- When you finish logging the feature, just press MENU and select the Close <feature name> option.

Page 26

Selecting the Repeat

Feature option

6. Repeating a Feature If you close a point, line or area feature and want to log

the location of another feature of the same type and with an identical description, use Mobile Mapper’s Repeat Feature function.

- After closing a feature, MobileMapper Pro takes you back to the Feature List screen. Then do the following:

- Move to the next similar feature you want to log

- Then press MENU, highlight Repeat Feature and press

ENTER. This starts feature logging. Note that the feature has the same attribute description as the former one

- After logging the GPS position(s) of this feature, high-

light the Close field and press ENTER to close the feature.

7. Nesting a Feature When you are logging GPS positions to a feature, you may

find another feature that you also want to log. Rather than log the entire feature and come back to record this other feature, you can simply pause the feature being logged, log the other feature, close it and resume logging the first feature.

Logging one feature while you have paused another feature is called “nesting.” You can nest any feature, point line or area, into any line or area feature. It is not possible to nest a point feature inside another point feature. Nesting is particularly useful when you are mapping things such as a road with streetlights along the route or a shoreline with stretches of erosion along it and the locations of certain habitats.

Page 27

Assuming you are logging a line feature and the Logging screen is displayed, do the following, for example to nest a point feature:

- Press MENU, highlight Nest Feature and press ENTER.

This pauses the logging of the line feature.

- Move to the location of the feature you want to nest

- In the Feature List screen now displayed, highlight the feature you want to nest and press ENTER

- Describe the attributes of the feature as explained above

- Highlight Close at the bottom of the screen and press ENTER. This closes the nested feature and takes you back to the Logging screen of the paused feature

- Press MENU, highlight Resume <feature name> and press ENTER. This takes you back to the Logging screen from which you can normally finish the logging of this feature.

8. Offsetting a Point Feature Sometimes the feature you want to put on the map is in

area of poor GPS reception or is not accessible. This is when you can map the feature using the offset utility. By combining the receiver’s position with the bearing and distance to the feature, MobileMapper Pro will automatically calculate and record the position of the feature. To input an offset for a point feature, assuming the Feature List screen is now displayed, do the following:

- Highlight one of the listed point features available from the selected feature library and press ENTER

- Press MENU, highlight Offset and press ENTER.

Page 28

Point Offset screen

If you do not have a

compass, you can use

MobileMapper Pro’s

Compass screen (see

also page 40) to deter-

mine the bearing to the

offset feature. If you

have been moving for 5

to 10 seconds along a

straight line, the Com-

pass screen will tell

you your bearing. You

can use this to deter-

mine the bearing to the

offset feature. CAU-

TION! The receiver

cannot determine

direction while station-

ary and the compass

direction remains the

same even if you rotate

the receiver.

This displays the Point Offset screen on which you should enter the following parameters:

Bearing: Compass direction to the feature from your current position. You need a compass to measure this angle (see also opposite). To input a value for Bearing, press ENTER and increment or decrement the highlighted number using the up/down arrows. To edit another digit, use the left/right arrows. When you are done, press ENTER again. Press the down arrow to move the cursor to the next field. Horz. Distance: Horizontal distance to the feature from your current position. Enter a value for Horz. Distance as described above for Bearing. When you are done, press ENTER again. Vert. Distance: Vertical distance to the feature from your current position (“0” if the feature and yourself are at the same elevation -on a flat area). Enter a value for Vert. Distance as described above for Bearing. When you are done, press ENTER again.

- Then press ESC to return to the Logging screen. This

writes the offset into memory, but you can edit it later if you like by going through the same process. If you close the feature and return to the Map screen, you will see that the feature is offset from your position in the middle of the screen.

Visual estimation for

horz. & vert. distances

is usually good enough

in terms of accuracy.

9. Offsetting a Line or Area Feature For the same reasons as a point feature (see previous

page), you may need to use the offset utility to map a line or area feature. By combining the receiver’s position with the direction and the distance to the feature, MobileMapper Pro will automatically calculate and record the location of the feature. To input an offset for a line or area feature, assuming the Feature List screen is now displayed, do the following:

- Highlight one of the features available from the open feature library and press ENTER.

- Press MENU, highlight Offset and press ENTER. This displays the Line or Area Offset screen on which you should enter the following parameters: Direction: Location of the feature with respect to your actual path. To input a value for Direction, press ENTER, choose one of the two options (Right or Left) and press ENTER again. Press the down arrow to move the cursor to the next field. Horz. Distance: Horizontal distance to the feature from your current position. To input a value for Horz. Dis- tance, press ENTER and increment or decrement the highlighted number using the up/down arrows. The units are those that you selected during receiver Setup. The default is meters. To select other units, see page 6. To edit another digit, use the left/right arrows. When you are done, press ENTER again. Press the down arrow to move the cursor to the next field.

Page 30

Visual estimation for

horz. & vert. distances

is usually good enough

in terms of accuracy.

To operate the grid

mapping utility, you

will need a measure-

ment device - anything

from a depth sounder

to a ruler, your own

sense of smell or your

ability to make visual observations. You will also need a compass.

Vert. Distance: Vertical distance to the feature from your current position (“0” if the feature and yourself are at the same elevation -on a flat area). Enter a value for Vert. Distance as described above for Horz. Distance. When you are done, press ENTER again.

- Then press ESC to return to the Logging screen. This writes the offset into memory, but you can edit it later if you like by going through the same process. Note: Offsets to area features are applied in MobileMapper Office and not in the receiver.

10.Logging GIS Data on a Preset Grid Feature The MobileMapper Pro's Grid Mapping Utility is an easy

way to automatically set up a series of GPS waypoints to facilitate the logging of data in an orthogonal grid. This utility assures that you gather measurements made using field sensors such as chemical detectors, depth sounders and magnetometers at an evenly distributed set of locations. This in turn assures the creation in your GIS of contour maps with a prescribed density of data and without any gaps that might force you to return to the field. The Grid Mapping Utility deals with two different grid concepts: grid features and grid points.

- Grid features are arrays of uniformly spaced waypoints oriented in rows and columns

- Grid points are navigation features similar to waypoints.

To log GIS data on a preset grid, do the following:

- If you have created a waypoint to help you locate the first grid point, you can use any of MobileMapper Pro's navigation screens to get there. To access a waypoint file you can use to navigate to the point of beginning, press the MENU button and select the GOTO option. Then select the User option. This will place the waypoint symbol and label on the base map displayed on the receiver's Map screen. Again, you may use any of the MobileMapper Pro's navigation screens to arrive at this waypoint.

- Once you arrive at the point of beginning, you should open up the job file that includes the feature library describing the grid. If you opened an existing job, press LOG to take you to the New Feature screen. Then select the grid feature type listed on the screen. Usually the term “grid” is included somewhere in the feature name so that you can easily recognize this type of feature. After selecting the grid feature, the Grid Setup screen appears on which you can read the definition of the grid (spacing, columns, rows and heading).

- Record an observation or measurement: With the OK field highlighted, just press ENTER. This takes you to the Logging screen that indicates that you have begun logging data to the feature and that the receiver is ready to log the feature's attributes. Remember that you remain stationary for all point features. Describe the feature as you would any other point feature.

Page 32

It is also possible to

navigate to any grid

waypoint (or any loca-

tion for that matter) on

the Map screen by

moving the arrow key

over another grid way-

point and pressing

ENTER. After you

record data at this

location, the Next Pt

field may still be

selected to go to the

next grid waypoint in

the network.

- Navigate to the next grid point: When you have fin-

ished recording the first point feature, you can select Next Pt at the bottom left to navigate to the next grid waypoint and record the next point feature within the grid. This takes you to the Map screen where you can see your current position marked by the arrow and the next grid waypoint highlighted with a “crossed box” target symbol. Small red circles indicate the locations of all the unvisited grid waypoints. The locations of where you recorded point feature are indicated by small black squares. As you begin moving toward the target symbol, you will see your heading indicated by the direction of the arrow marking your position. Adjust your movement as necessary until you are positioned over the target symbol. You may also use any of the other navigation screens available with your MobileMapper Pro. The Arrival alarm is disabled when navigating to grid waypoints. It is best to note your distance to the next waypoint and stop when this value goes to zero. When you arrive at the next grid point, press the LOG button and you will see the same Logging screen you used for the earlier measurement or observation. Each grid waypoint is a geographic coordinate you should make every effort to occupy so that the data you record is evenly spaced and complete. However, each grid waypoint is merely an aid for navigating to the ideal location for an observation or measurement. All the data you record is ascribed to the position of the MobileMapper Pro receiver and NOT to the grid waypoint.

Page 33

If you cannot physically occupy this waypoint, but can make the necessary visual observation, you should do so and record an offset estimating the distance and bearing to the grid waypoint. If you are recording measurements made by an instrument, you should NOT record an offset but rather try to make a recording as close as possible to the position.

- When you have occupied as many of the grid waypoints as you can and recorded the necessary observations and measurements at each, highlight the Close field at the bottom of the Logging screen and press ENTER. This closes the grid feature and returns you to the New Feature selection screen where you may either log data to another feature, even to another grid, or close the entire job.

11.Changing the Parameters of a Grid Feature Before Logging GIS Data

When you navigate to the location of the grid, you may decide to readjust the size and orientation of the grid based on field observations that you did not foresee back in the office. For example, you may find that navigating to waypoints with an east-west orientation is not feasible if the area of interest is situated on a narrow strip of land between two north-south running streams. When you change the definition of a grid, MobileMapper Pro always assumes that you are standing in the corner of the grid from which you can see the grid extend in front of you and to the right.

In the open job, do the following:

- On the Feature List screen, select the grid feature and press ENTER. On the Grid Setup screen that is now displayed, set the parameters listed below.

Spacing: Distance between any two consecutive waypoints in any row or column (default: 50 meters or 100 feet, depending on the units used)

Columns: Number of waypoints along the axis facing you (default: 10; Max.: 100) Rows: Number of waypoints along the axis perpendicular to the direction you are facing (default: 10; Max.:

100) Heading: Direction you face when the grid’s columns extend in front of you and the rows extend to your

right. To change the above parameters, use the up/down

arrows to move the cursor to each of these fields, press ENTER, use the up/down arrows to increment/decrement the highlighted figure, use the right/left arrows to highlight the next/previous digit in the field. When you are done with the definition of a field, press ENTER. Then press the down/up arrow to access the next field, etc. Once these parameters have been changed, highlight OK at the bottom of the screen and press ENTER

- This takes you to the Logging screen from which you start logging data as explained previously.

12.Closing a Job

To close a job, press MENU and select the Close Job option. To open another job, use the Open Job option after pressing the MENU button.

Page 35

To achieve the best

accuracy, it is impor-

tant to hold the

receiver vertical and at

eye level. This allows

the internal antenna to

pick up signals from

the GPS, WAAS and EGNOS satellites. This is especially true when

recording data for post-

processing.

GPS Accuracy

MobileMapper Pro provides 5- to 10-m autonomous accuracy around the globe assuming the receiver is tracking five GPS satellites and the PDOP < 4 (which is almost all the time).

MobileMapper Pro is also capable of providing 2- to 3-m horizontal accuracy using real-time differential corrections from its built-in WAAS/EGNOS receiver. You must be in North American to make use of the free WAAS signals broadcast by the US Federal Aviation Administration. You must be in Europe to make use of the free EGNOS signal broadcast by the European Union. If you are receiving a WAAS or EGNOS signal, a “W” appears on all logging screens.

In addition to WAAS/EGNOS, MobileMapper Pro will automatically apply real-time differential corrections from land-based systems such as Coast Guard beacons or your own privately broadcast RTCM Type 1 or Type 9 corrections. Just use the serial cable to connect your MobileMapper Pro to a differential correction receiver. A "D" will appear on the MobileMapper Pro's logging screen when the receiver detects RTCM input.

The accuracy with land-based systems is approximately the same as with WAAS/EGNOS. However, it is possible to improve accuracy by one or two decimeters if you broadcast your own RTCM corrections while keeping the distance between the broadcasting reference receiver and the rover receiver less than 10 km (3 miles).

If you average positions for a point feature for a few minutes, even better accuracy is possible.

Page 36

GPS quality indicators

Tracking 3 satellites

will allow you to calcu-

late a 2D position (lat/

lon) using the last alti-

tude recorded by the

receiver. You need to

track at least 4 satel-

lites to get a 3D posi-

tion (lat/lon/altitude).

To achieve the speci-

fied accuracies for

MobileMapper Pro, you

will need to track 5 or

more satellites.

MobileMapper Pro will warn you if the PDOP, and therefore the accuracy, of your positions has dropped below the level you selected during Setup (see page 65, the PDOP alarm option). If you see this warning you may press the ESC button and continue logging.

However, if you are recording line or area features, you might want to return to the field when the GPS satellites are in a better configuration overhead (the constellation changes slowly but constantly).

And if you are recording a point feature, you should strongly consider moving to another location with better satellite reception and recording an offset (distance and bearing) to the feature.

GPS Quality Indicators

At the bottom of each logging screen, you can see two numbers that give you a good indication of how accurate your positions should be.

The first is the number of satellites that the receiver is tracking.

The second number is the Positional Dilution of Precision (PDOP), which is an estimate of accuracy that the receiver constantly calculates using the geometry of satellites in the sky. The more satellites that are being tracked and the more evenly they are distributed around the sky, the better the accuracy. PDOP values less than 4 or 5 are good. If the PDOP value is over 10, you should consider moving to an area with a clearer view of the sky and recording features with offsets.

Job List screen

Note that you are not

prompted to select a

feature library when

you select an existing

job. This is because

the library that was

selected when the job

was created is neces-

sarily the one that must

be used for the job

when re-opening this

job.

Revisiting and Updating Existing GPS/GIS Jobs

You can use MobileMapper Pro not only to position and describe new GIS features but also to update information gathered previously. This is particularly useful when collecting data on things that change over time: streetlight bulbs burn out, new roads are added to housing developments, new crops are planted, etc.

1. General Procedure Return to the area where the original job was recorded and

turn MobileMapper Pro on. When it has calculated a GPS position, follow the procedure below to update the job or to append more data to it.

- Press the LOG button, select the Open Existing Job option

and press ENTER. MobileMapper Pro lists all the jobs present in its memory.

- Press the down arrow to highlight the name of the job you want to update and press ENTER. MobileMapper Pro displays the navigation screen that was last used.

- Unless this screen is already displayed, press NAV repeatedly until the Map screen is displayed. From this screen, you will now indicate the first feature you want to revisit. If necessary, press the IN or OUT button to adjust the scale so you can see this feature.

- Press any arrow key to switch to the cursor mode on the Map screen and then use the arrow keys to move the cursor over the feature you want to revisit first. It’s a good idea to keep the Map info visible on the screen as it tells you exactly when the feature is selected. (The feature name appears in the lower part of the screen when the cursor is positioned over the feature.)

Page 38

Selected screen

Map screen showing

straight line to target

NOTE: If the MobileMapper Pro receiver automatically shuts off due to low power while a job is open, it is better to change the batteries and create a new job with a similar name rather than append more data to to the job that was closed due to power loss. For example, if the first job was named JOB1.MMJ, you can call the second job JOB1A.MMJ. You can easily merge both jobs in MobileMapper Office, and save the file as JOB1.MMJ. No data will be lost and you will be able to reopen this job at any time and edit the existing file or append new data to it.

- When the map cursor is positioned over the feature to be updated, press ENTER. The Selected screen is now displayed showing the attribute values currently ascribed to the feature. Note that the Goto field is highlighted at the bottom of the screen.

- Press ENTER to ask MobileMapper Pro to guide you to this feature. If you simply press ENTER, you will make the selected feature your destination and all the navigation screens will be set to help you reach that feature. Press NAV to access any of these screens. On the Map screen, you can now see a straight line connecting your current destination to the selected feature.

- Walk to the feature according to the navigation instructions provided on the Map screen. You can use other navigation screens if you prefer (see also Navigation Screens chapter from page 36). You will know when you are close to the feature when the distance to the feature goes to zero or close to zero, or simply because you can identify it visually. Another nice way of being informed that you have arrived at the feature is to set the Alarms option (see explanations on page 65)

Page 39

Selecting

Update Position

- After arriving at the feature, press the LOG button. This takes you back to the Selected screen.

- Now that you are near the feature, highlight the Edit field and press ENTER. You are now allowed to edit each of the feature’s attributes.

- After reviewing the attributes that need to be changed, highlight the Close field at the bottom of the screen and press ENTER. This ends the review of this feature and displays the Map screen again.

- Follow the same 7 steps described above to revisit and update the other features present in the job.

2. Repositioning a Point Feature

If a point feature appears to be mislocated on the Map screen, do the following after you have arrived at the feature and the Selected screen showing all the feature’s attributes is displayed:

- Press MENU, select the Update Position option and press ENTER.

If you press NAV and go back to the Map screen, you will now see two features (one at the old position, the other at the new position). To remove the feature's old position from the display, just move the map cursor so that the feature is off the screen. When you move the cursor back to the feature, only the new position will be visible.

NOTE: The Update Position function applies only to point features. When editing the attributes of a line or area feature, the function is not accessible. If you wish to reposition a line or area feature, you should record a new feature and then delete the old one in MobileMapper Office.

Page 40

3. Adding More Features and Attributes to the Job If you want to add more features and descriptions to the exist-

ing job, you just have to record them exactly as you record features into a new job.

4. Closing the Job To close the job, all you have to do is open up another job or

turn the receiver off. To open another job, use the Open Job option after pressing the MENU button. You cannot accidentally lose data with MobileMapper Pro without opening the receiver and losing or damaging the internal memory card, i.e., the SD card.

Post-Processing Option

MobileMapper Office includes a differential correction utility that can post-process GPS measurements recorded by MobileMapper Pro for submeter accuracy. To record these GPS measurements in a MobileMapper Pro receiver, you need to first purchase a post-processing option.

When you purchase this option, you are given an activation code that you should enter into your MobileMapper Pro receiver. Because it is tied to the serial number of your MobileMapper Pro receiver, the activation code is valid only for one receiver.

Enabling the Post-Processing Option

- Press MENU. Use the up/down arrows to highlight Setup and press ENTER.

- Use the up/down arrows to highlight Post-processing and press ENTER. This displays the Activation Code screen.

- Overwrite the “0000000000” field with the activation code intended for your receiver. Use the up/down arrows to set each digit and the right arrow to move the cursor to the next digit. You can move the cursor back to the previous digit, if necessary, by pressing the left arrow.

- After entering the code, press ENTER. This enables the post-processing option in the receiver. MobileMapper Pro comes back to the Setup menu where Post-processing is still highlighted but you can no longer access the Activation Code screen.

enabled

If you then press MENU and come back to the Setup menu, the Post-processing option will no longer be there because you only need to enter the Activation Code once.

Creating a New Job with the Post-Processing Option

- If there is a job that is currently open, close it by pressing

MENU and selecting Close Job

- Press LOG. MobileMapper Pro displays the Welcome screen. This screen shows three options (instead of two when the post-processing option is not enabled).

-Highlight Create New Job and press ENTER.

- Enter the job name as explained earlier (see page 12).

- After entering the name, highlight the OK key on the screen and press ENTER. A new screen is then displayed listing the feature libraries stored on the receiver’s SD card.

- Highlight the library you want to use and press ENTER. A new screen is then displayed asking you to choose the job mode:

• Real-time: If you select this job mode, the receiver will

record only feature positions and descriptions and GPS metadata. Jobs recorded in real-time mode cannot be differentially corrected later on.

• Post-processing: Select this job mode to allow

MobileMapper Pro to record the job so that later on, it can be post-processed in MobileMapper Office. In this job mode, MobileMapper Pro will record GPS measurements files in addition to the MMJ job file that is recorded in real time.

Job Mode screen

Site ID screen

- Use the down/up arrow to highlight Post-processing and

then press ENTER. The screen now lists all the features available from the selected feature library.

- At this stage, use MobileMapper Pro in exactly the same way as you would without the post-processing option being enabled. See page 13 and following.

Using MobileMapper Pro as a Reference Station

- Mount MobileMapper Pro on a tripod placed over a control point, turn it on and press ENTER at the agreement screen

- Press LOG. MobileMapper Pro displays the Welcome screen.

- Highlight Reference Station and press ENTER. The Site ID screen is now displayed.

- Enter a Site ID (there is a four-character limit) as you would enter a job name, highlight OK on the screen and press ENTER.

From now on, MobileMapper Pro will operate as a reference station until you turn it off. It is therefore important that you not move the receiver or any optional external antenna until the receiver has turned off.

Before leaving the reference station for your work, press the NAV key until you can see the Satellite Status screen. The letter “R” appears in the upper-right when the receiver is recording reference station data.

Map screen in

cursor mode

The Map screen is always in the Position mode when you access this screen. In this mode, your present position is indicated by the large arrow icon in the center of the display. If you are moving, the arrow will point in the direction that you are heading. At the bottom of the screen is the scale for the map displayed and two data fields that can be customized, or turned off, depending upon your needs.

The present position icon will change to an hourglass when the MobileMapper Pro is unable to compute a position fix due to poor signal reception.

Press any of the arrow keys to switch to the Cursor mode. In this mode, you are provided with a cross hair cursor that can be moved on the map with the arrow keys. At the bottom of the display is the information for the position of the cursor relative to your present position (heading and distance). Also any points of interest or GIS features that the cursor is over will be shown.

To return to the Position mode, press ESC. The cursor will disappear and the present position icon will appear centered on the map.

To set and/or customize the Map screen, use the functions described below. These context-sensitive functions are accessed by pressing the MENU button while the Map screen is displayed.

Show/Hide Map Info

Use this option to show or hide the two data fields displayed at the bottom of the Map screen. To customize these fields, see Select Map Info below.

Select Map Info

Use this option to tell MobileMapper Pro which data should be displayed at the bottom of the Map screen. This can be:

- Customize Fields. This function is equivalent to the Custom- ize function available from all navigation screens other than the Map screen. See page 47.

- Street info: This option displays an information block at the bottom of the display showing the name of the street your present position or cursor is on. If in the cursor mode, the bearing and distance from your present position are displayed.

Map Setup

You can make the following settings using the Map Setup option. To access this option, press MENU when the Map screen is displayed, select Setup and then select Map Setup. The screen that appears contains two tabs: the Format and Display tabs.

On the Format tab, you can set the following parameters:

- Orientation: You can change how the map is orientated on the screen to either North Up, Course Up or Track Up. Default is North Up.

- Detail: Use this field to set the map detail. The detail of the map can be set to highest, high, medium, low or lowest. This changes the zoom level that different map objects (cities, highways, labels, etc.) are displayed. If you have set a zoom level and the display is too cluttered, set the map detail to a lower level; conversely set it to a higher level to view more detail.

- Track Mode: Inactive (Track history disabled in MobileMap-

per Pro)

- Primary Usage: MobileMapper Pro can be set to either Land or Marine usage. When in Land (default), the map displays land areas in white and water areas in blue. For marine applications it may be desirable to reverse the display, showing water as white and land as blue. This will make reading some of the data information on the water easier.

From the Display tab, you can customize the Map screen by specifying the items that MobileMapper Pro should display on the map:

- Waypoints

- Track Lines (default: cleared; Track history disabled in MobileMapper Pro)

- Pos-Dest Line (line connecting current position to destina- tion)

- Depart-Dest Line (line connecting initial position to destination)

Check the items you want to show and clear those you want to hide. You can also check or clear all these items in a single operation by respectively selecting Mark All or Clear All just above these items and then pressing ENTER.

Goto Cursor

If the Map screen is in cursor mode, the first option available from the list displayed after pressing the MENU button is Goto Cursor. Select this function when you want MobileMapper Pro to guide you to the location where the cursor currently is on the Map screen. Starting from your current location, MobileMapper Pro will indicate the distance to go and the heading to the cursor location.

Compass Screen

The two data fields on top are customizable. The lower portion of the Compass screen not only displays your heading in a graphical manner, but also displays the relationship of the sun, moon and your destination (if navigating on a route) to your heading.

The Compass screen contains the following information, from top to bottom:

- In the title bar: destination name if you are using the Goto function

- Data Fields: customizable data fields (see Customize option below). Some of the data displayed requires you to be moving to be computed. Invalid data is indicated by dashes.

- Icon representing destination: Displayed outside the compass when you are using the Goto function. This provides you with the direction you need to head to arrive at the destination. When you are on course and heading straight for the destination, the destination icon will be lined up with the heading marker

- Compass/Heading marker: Using the compass and the heading marker, you can view your heading information in a familiar manner. Note that you need to be moving for this data to be valid.

You can customize the Compass screen by pressing the MENU button while the screen is displayed. For more information, see page 47.

Selecting a GIS feature

on the Map screen

GOTO Function

Purpose

You use the GOTO function to ask MobileMapper Pro to guide you from your current position to a destination point.

After you will have specified which destination point to go to, you will select your favorite navigation screen. You will then be able to read the information computed by MobileMapper Pro to help you reach the destination.

Destination Point Types

Not only can MobileMapper Pro guide you to previously logged GIS features but also to other pre-loaded or created points. In fact, the destination point can be any of the following:

- Any feature logged in the open GIS job which you will select graphically on the Map screen

- Any waypoint created earlier using the MARK function. This type of point is stored as a “User” Point of Interest (POI)

- Any point of interest (POI) pre-loaded in MobileMapper Pro.

Selecting a GIS Feature as the Destination Point

Press NAV until the Map screen is displayed. Press the arrow button in any direction to make the selection cursor appear and to position it over the feature you want to go to. You know that the cursor is positioned over the feature when the “Cursor” indication at the bottom of the screen is replaced with the name of that feature.

Press ENTER. A new screen appears giving the current description of the feature. At the bottom of the screen, the Goto field is highlighted: simply press ENTER again to enable the Goto function with this feature as your destination. Then select your favorite navigation screen, using the NAV button, and navigate to this feature.

Page 57

NOTE: If you have

already pressed the

arrow keys and one of

the nearest points in

the list is highlighted,

use the ESC button to

scroll back to the Near-

est To field.

Selecting a POI as the Destination Point

Press MENU, scroll to the GOTO option and press ENTER. The possible categories of POIs are now listed on the screen. Select the category the destination point belongs to.

Before pressing ENTER to list all the points stored in this category, choose how you want these points to be listed by setting the Find By field. Press the left/right arrow to set this field. Two values are possible in this field:

- Alphabetical: Points will be listed in alphabetical order.

MobileMapper Pro will then help you find the desired point through one of the following two methods: Keyboard

Search and Alphabetic Scroll. Keyboard Search: Before displaying the list of points in

alphabetical order, MobileMapper Pro displays a keyboard that you can use to enter the first few characters of the point you are looking for. When you highlight OK and press ENTER, (or as a shortcut, press IN), you are taken to the alphabetical list with the point you began typing at the top of the display. Anytime you are viewing the list of points, you can re-access the keyboard by pressing ESC.

Alphabetic Scroll: You can use the IN and OUT buttons to step up or down the alphabet. If you were viewing points beginning with the letter “A”, pressing OUT would take you to the first waypoint beginning with “B”, and then “C” and so forth. Pressing IN does the same function but only in reverse.

- Nearest To: Only the 20 points from this category the clos-

est to your position will be listed. When these 20 points are listed, MobileMapper Pro indi-

cates the bearing and distance to your current position from the first point in the list. You can change the point from which the nearest points are found. With the Nearest To field now highlighted, press ENTER and scroll to the category where this new point can be found. Select a new point and press ENTER.

Page 58

Mark screen

The Mark option from

the Menu list provides

a function similar to

the LOG button when

held down for 2 to 3

seconds.

Saving Your Current Position as a Waypoint

Saving your current position as a waypoint is very easy and can be done regardless of whether a GIS job is open or not.

From any navigation screen, just hold down the LOG button for 2 to 3 seconds until the Mark screen is displayed. This screen provides the description of the waypoint you are about to save.

You can accept all the defaults by simply pressing ENTER (Save field already highlighted).

You can also edit the Icon, Name and Message fields using the arrow keys to access these fields. Obviously you should keep the Location and Elevation fields unchanged as they contain the coordinates of your current location.

Waypoints recorded using the receiver's Mark feature are not exportable by MobileMapper Office. If you wish to record waypoints in the field and export them to GIS formats, you should use MobileMapper Office's Feature Library Editor to create a "Waypoint" feature type. You can then log a "waypoint" as a point feature while recording a job file.

Creating a Waypoint With the Map Cursor

This is another way of creating a waypoint whose coordinates will be based on the location of the cursor on the Map screen.

Press NAV until the Map screen is displayed. Press any arrow key to make the cursor visible on the map. Move the cursor to the desired location on the map using any arrow keys. Hold down the LOG button for 2 to 3 seconds until the Mark screen is displayed.

You can accept all the defaults by simply pressing ENTER (Save field already highlighted).

User Waypoint screen

Editing/Deleting a User Waypoint

You can edit/delete a waypoint from the Map screen:

- Press NAV until the Map screen is displayed

- Use the IN or OUT button, or move the cursor so that the waypoint you want to edit or delete is visible on the screen

- Position the cursor over that waypoint. The name of the waypoint then appears at the bottom of the screen.

- Press ENTER. This opens the Select Item screen on which MobileMapper Pro lists the names of waypoints and POIs present in the vicinity. Highlight the waypoint you want to edit/delete.

- Press ENTER again. This opens the User Waypoint screen on which you can see the definition of the waypoint (coordinates+comments). At the bottom of the screen are three command fields that you can use for the following tasks:

Edit (default choice): Select this field if you want to edit the definition of the waypoint. The following parameters can be changed: icon, name, coordinates, elevation and comment.

Goto: Select this field if you want MobileMapper Pro to guide you to this waypoint

Del: Select this field if you want to delete the waypoint. MobileMapper Pro will then ask you to confirm that you really want to delete the selected waypoint.

A GOTO route is a one-

leg route whose two ends are your current position and the cho-

sen destination point.

WPT6

WPT5

Routes

As explained below, MobileMapper Pro can handle two types of routes: GOTO route and multi-leg route.

GOTO Route

This in fact a route that you define when:

- You select a feature on the Map screen, you press ENTER to display the attributes of this feature, and you press ENTER again to enable the Goto function to this feature (by default, the Goto field at the bottom of the screen is highlighted). The same can be done to choose a POI or a waypoint as the destination point.

- You use the GOTO option from the Menu screen and you choose a POI or waypoint as the destination point.

GOTO routes are not saved in memory. When you turn your MobileMapper Pro off and then back on, the GOTO route is gone. You need to create a new GOTO route if you intend on completing the route.

Multi-leg Route

A multi-leg route consists of several waypoints or POIs that you should reach one after the other. The segment between any two consecutive waypoints or POIs is called a “leg.” Unlike GOTO routes, multi-leg routes can be stored in memory.

The first waypoint in the route is now defined and you are now prompted to define the second one. Resume the instructions in this paragraph for the second point, then for the third, etc.

When the last point of the route is defined, highlight the Save Route field on the Create Route screen and then press ENTER to save the route.

2. Activating/deactivating a Multi-Leg Route Press NAV to display a navigation screen, press MENU, scroll

down to Routes and press ENTER. In the Route List screen now displayed, scroll down the list

and highlight the route you want to activate. Press MENU, highlight the Activate Route option and press ENTER. MobileMapper Pro comes back to the Route List screen where the activated route now appears in bold characters. Press NAV to navigate along this route.

To deactivate this route, press MENU, highlight Routes, press ENTER, highlight the activated route (shown in bold characters), press MENU, highlight Deactivate Route and press ENTER. The route is now deactivated.

Page 62

3. Other Functions Tied to Routes

You can also do the following on the highlighted route using the functions available from the MENU button (see also diagram on page 59):

- Viewing the route on the Map screen by highlighting the Map View Route option and pressing ENTER. The Map screen then appears showing the route. Press ESC to come back to the Route List screen.

- Editing the route by highlighting the View/Edit Route option and pressing ENTER. From the View/Edit screen you can then press the MENU button to access options allowing you to insert, delete, replace the highlighted waypoint and then to save the changes made to the route.

- Reversing the route, i.e. reversing the direction of travel along the route, by highlighting the Reverse Route option and pressing ENTER. This instantly reverses the route. Note that the first and last waypoints in the route name have been swapped.

- Deleting the route by highlighting the Delete Route option and pressing ENTER. A message will appear asking you to confirm this operation.

- If a route has been activated, selecting the leg you want to follow by selecting the Select Leg option and pressing ENTER. The screen then shows the list of points making up the route. Select the point you want to navigate to and press ENTER. A warning message will appear asking you to confirm the leg change. After choosing Yes or No, press ESC twice to return to the navigation screen.

In the previous chap-

ters, we have intro-

duced most of the

context-sensitive func-

tions available from the

menu list. In fact,

these functions are

closely tied to

MobileMapper Pro’s

main functionality (GIS

data logging and navi-

gation). In this chapter,

we present the supple-

mental functions.

MENU button

The list of functions that you can have access to by pressing the MENU button depends on which navigation screen is displayed and whether GIS data logging is in progress or not. The context-sensitive functions are always listed first in the menu list (after the ever present Open Job / New Job or Close Job options). The other functions, which are always available as long as the MENU key is active, are always last in the list. On the menu screen, a horizontal line separates context-sensitive functions from the other ones.

The diagram below shows the available functions when pressing MENU while navigation screens are displayed and no GIS data logging is in progress. These functions are listed in the same order as on the screen. Context-sensitive functions appear in the upper frames. Lines connect the context-sensitive functions to the permanent functions so you can see what the entire menu is made of in each context.

When data logging is in progress and one of the navigation screens is displayed, then the functions specific to the selected navigation screen and to GIS data logging add up in the menu (functions specific to data logging are listed first).

(See also Routes option, page 59, for which the MENU button gives access to specific functions.)

When you select the Setup option in the menu list, another menu is displayed containing a number of options, as shown in the above two diagrams.

All the options available from the Menu screen are described below.

Page 66

Open Job

This option provides another way of opening a GIS job. It is similar to selecting the Open Existing Job option that is prompted on the screen after pressing the LOG button when no job is open yet. Selecting this option when a job is already open allows you to close the currently open job and open another one.

New Job

This option provides another way of creating a new GIS job. It is similar to selecting the Create New Job option that is prompted on the screen after pressing the LOG button when no job is open yet.

Mark

This option allows you to quickly create a new waypoint whose coordinates will be those of your current location.

A typical use of this option is when you are located at a new point of interest and you wish to log its position.

When you select Mark in the menu list, MobileMapper Pro displays the Mark screen with the following default values:

- Default icon in the Icon field

- “WPTxxx” as waypoint name in the Name field. “xxx” is a number that MobileMapper Pro automatically increments as you create new waypoints

- Coordinates of your current location in the Location and Elevation fields

If you agree with all these parameters, and as the Save field is already selected at the bottom of the screen, you just have to press ENTER to create the new waypoint. This is the fastest procedure to create a new waypoint.

On the other hand, if you have to change any of these parameters or add a comment in the Message field, then you have first to edit the corresponding fields before selecting the Save field and pressing ENTER

Page 67

If you would like to add more description or if you would like to export a waypoint to your GIS, use a feature library that includes a point feature called “Waypoint” and whatever level of attribution that you need. Then, when you want to record a waypoint, you can select the Waypoint feature type from the feature library and record a fully describable and exportable point feature.

GOTO

This option is discussed in detail on page 48.

Change Map screen

Instructions for

creating DirectRoute

maps and for using the

special navigation

screens are found in

the DirectRoute Quick

Start Guide and User

Manual.

1. Initialize This option guides you through the complete procedure

that allows you, any time, to initialize MobileMapper Pro.

2. Select Map This option is mainly used to choose the base map used as background map on the Map screen. The following param-

eters can be set on the Change Map screen:

- Basemap: If you did not upload a background map to MobileMapper Pro, then only the Default Map option can be selected in this field. The default map is always present in MobileMapper Pro. If an SD card containing specific maps is installed in the receiver, then you can choose one of them as the one shown on the Map screen.

- Detail Map: If you did not upload a background map to MobileMapper Pro, then only the Empty option can be selected in this field as the default map only has one level of details. If an SD card containing specific maps is installed in the receiver and you chose one of them in the previous field, then you can choose the level of details you wish to see on the Map screen.

After choosing the desired options for these parameters, highlight the Save field at the bottom of the screen using the down arrow and then press ENTER.

NOTE: The latest release of receiver software makes MobileMapper Pro compatible with background maps made by the separately sold PC application Magellan® MapSend® DirectRoute™. You use MapSend DirectRoute™ PC software to create and upload special background maps into your MobileMapper Pro receiver. Selecting one of these maps in the MobileMapper Pro receiver enables special navigation screens that allow you to navigate to street addresses, points of interest or GIS features along streets and not just point-to-point.

3. Map Setup This option allows you to set the viewing options for the Map screen (see page 38).

Page 69

Default coordinate

systems: Primary: Lat/Lon Secondary: UTM

4. Nav Screens This option allows you to remove the navigation screens

that you do not need from the navigation screen sequence that you scroll by pressing NAV repeatedly (see page 36). When selecting this option, you are asked to turn off or on each of the available navigation screens. Choose “Off” and press ENTER for all these screens that you are not currently using. Note that the Map screen cannot be turned off. You must cycle through all the screens in order to save any changes to the On/Off status of any screen.

5. Coord System This option allows you to define a primary coordinate sys-

tem, and also a secondary coordinate system if you need one. By defining a coordinate system, you tell MobileMapper Pro how the calculated coordinates should be expressed. For example, if you choose Lat/Lon, all coordinates will be expressed as angles (latitudes and longitudes) and if you choose UTM or any other system, coordinates will all be distances (Northings and Eastings) from the chosen origin. When you select the Coord System option from the Setup menu, MobileMapper Pro asks you to specify which system you want to define (primary or secondary). Select it and press ENTER. In the list that appears, select the coordinate system you want to use and press ENTER. Depending on your choice, MobileMapper Pro may then ask you additional information:

- If you select Lat/Lon, you are then asked to select the display format (DEG/MIN.MMM, DEG/MIN/SEC.SS, etc.)

Page 70

- If you select any system other than Lat/Lon or UTM,

you are asked to choose a scaling factor for displaying position coordinates: 1 meter, 10 meters or 100 meters. If you choose 1 meter, a northing coordinate will be displayed as, for example, 249143N. If you chose the 10-meter factor, the same coordinate will be displayed as 24914N. And if you select the 100-meter factor, the coordinate will be displayed as 2491N.

- For some systems, you are asked to supply information

on grid zones or types

- For the User Grid, you are asked to supply a projection

type (Transverse Mercator, Lambert Conic, Stereographic, Oblique Mercator or Polyconic), coordinates of origin, scale factor, unit to meters conversion and false Easting and Northing at origin

Notes on Coordinate Systems:

- The handheld always uses the WGS 84 coordinates to locate the features and waypoints on the Map screen, even if you select some other coordinate system/datum.

- The coordinate systems and datums used to display anything on the Map screen are only for display. When you select some other coordinate system/datum, only the numbers of the coordinates of a feature/waypoint are changed. The map screen is not changed in appearance.

Page 71

Default Map datums

Primary: WGS 84

Secondary: WGS 84

Default Elev mode: 3D

6. Map Datum This option allows you to define a primary map datum,

and also a secondary map datum if you need one. A map datum is a geographic reference that MobileMapper Pro will refer to to calculate the coordinates of your

position. MobileMapper Pro holds more than 70 different map datums in its memory.

After selecting the Map Datum option from the Setup menu, choose the map datum from the list that applies to your country and working area and then press ENTER. To enter a user map datum, select the term “USER” in the list of datums arranged in alphabetical order. Then, for more information on how to enter a user map datum, refer to the appendix at the end of this manual (page 80).

7. Elev Mode This option allows you to choose between 3D and 2D

mode. In 3D mode, MobileMapper Pro will compute the 3 coordinates of your position: horizontal coordinates plus eleva-

tion. In 2D mode, MobileMapper Pro will not calculate your ele-

vation. Only the horizontal coordinates of your position will be computed. MobileMapper Pro will assume that the last computed or entered elevation is your current elevation. Operating in 3D requires at least 4 tracked satellites whereas 2D requires only 3. Consider using the 2D mode when the conditions of reception are poor or if the working area is relatively flat and elevation is not important. After selecting the Elev Mode option from the Setup menu, choose the mode that matches your case of use and then press ENTER.

Page 72

Default time format:

Local AM/PM

Default units: km/m/

kph/hectares

8. Time Format This option allows you to select the time format you want

to use in MobileMapper Pro. You can choose from three different time formats: Local 24Hrs, Local AM/PM or UTC. After selecting the Time Format option from the Setup menu, choose the time format that suits you and then press ENTER. If you have selected Local 24 Hrs or Local AM/PM, you will be prompted to enter your local time.

9. Units This option allows you to select the units of measurement that will be used when displaying navigational data or fea-

tures being logged. All sets of units are formatted as follows: long distance unit/

short distance unit/speed unit/area unit.You can select from 5 different sets of units. You can also create your own set of units by selecting Advanced at the end of the list. You are then prompted to specify the unit you wish to use for each type of possible measure, i.e. Distance, Speed, Elevation, Bearing and Area. After selecting the Units option from the Setup menu, choose a set of units from the displayed list and then press ENTER. If you have selected Advanced, a new list appears prompting you to choose a unit for each type of measure. Select the first measure in the list, press ENTER, choose a unit and press ENTER again. This takes you back to the former screen where you can select the second measure, etc. When all units are defined, press ESC to come back to the Setup menu.

Page 73

Alarms menu

10.Alarms All of the Alarm options are set in the same way. The

instructions below apply to all of the Alarm settings. When the beeper is turned on for alarms (see Beeper option) an audible beep will be sounded for the alarm. A visual alert is displayed for the alarm whether the beeper is turned on or off. Setting the Arrival Alarm: The arrival alarm alerts you that you have arrived at the destination of your GOTO route or to the destination of any leg in a route you are navigating on. This option allows you to set how close you must come to the destination before the alarm begins to sound. After the alarm sounds, you can reset the arrival alarm to a shorter distance, but this shorter distance will apply to the next target and not to the current one. If you want the alarm to sound again when you come within a shorter distance to the current target, first select another target destination and then reselect the original target. Setting the PDOP Alarm: This turns on or off the alarm that can sound whenever MobileMapper Pro has lost its ability to compute accurate position fixes due to poor geometry of the GPS constellation. Generally, PDOP values less than or equal to “5” are indicative of good operating conditions. So it is a good idea to set this alarm to “5.” To turn off the PDOP alarm, enter “00.”

Page 74

Default North

Reference: True

Note: Apart from the Arrival and PDOP alarms, MobileMapper Pro will generate a warning message on the screen in each of the following two cases:

- “Low Memory.” This message will appear when the handheld is running out of memory. If a job is being logged, then the occurrence of this message will automatically stop GIS data logging. You will however be allowed to enter the attribute values of the current feature before the job is closed.

- “Out of Memory.” This message will appear when the memory is full. The occurrence of this message will immediately close the currently open job and you will not be able to log any new feature until you free some space in memory.

11.North Reference This option allows you to define the type of North reference you want MobileMapper Pro to use. This can be True

North, Magnetic North, Military True North or Military Magnetic North.

After selecting the North Reference option from the Setup menu, choose the desired North Reference from the displayed list and then press ENTER.

Page 75

Default: The appropri-

ate daylight saving

time (United States

and European Union

only) will automati-

cally be set during star-

tup when you use

MobileMapper Pro for

the first time.

Default: Off

It’s a good idea to use

this option when you

transport your

MobileMapper Pro with

its keypad unprotected.

This will prevent the batteries from being

entirely discharged if

the PWR button is

inadvertently

depressed.

12.Daylight Saving This option allows you to select the region where you are

located so that MobileMapper Pro can automatically adjust the time displayed to compensate for daylight saving time. You can select one of three possible regions:

- United States: Daylight saving starts on the first Sunday

in April and ends on the last Sunday in October

- European Union: Daylight saving starts on the last Sun-

day in March and ends on the last Sunday in October

- Customize: this option allows you to set the month and

day that daylight saving starts and ends in your area.

After selecting the Daylight saving option from the Setup menu, press ENTER again to list the three available regions. Choose one using the up/down arrow and then press ENTER. Press ESC to come back to the Setup Menu screen. If you chose Customize, first set all the displayed fields according to your local daylight saving times before pressing ESC.

13.Power Off Timer Conserving battery life is important to any handheld GPS

user. The Power Off Timer option provides another tool in saving battery life.

Selecting On will allow you to select the mode and how long MobileMapper Pro will stay powered on.

- If the Power off mode you select is Time, then the Power off Timer field allows you to select time that MobileMapper Pro will remain on before automatically powering off is no keys are pressed (1, 2, 4, 10, 30 or 60 minutes).

If the Power off mode you select is Position, the Power Off Timer field sets how soon MobileMapper Pro will be powered down when the position has not changed and if no keys have been pressed.

Page 76

Default: 50%

Default: 4 minutes

14.Contrast This option allows you to set the screen contrast. After

selecting this option, a new screen appears on which you can set the percentage of contrast using the left/right arrows to respectively decrease or increase that percentage. The impact of your contrast setting upon different color bars is instantly shown in the lower part of the screen.

15.Light Timer This option allows you to set the time interval that will be

used to turn off the display backlight when not in use. Times available are: 30 seconds; 1, 2, 4 or 10 minutes; or Timer Off.

After selecting the Light Timer option from the Setup menu, use the up/down arrow to highlight the desired choice and then press ENTER.

16.Beeper This option allows you to select which actions will cause

the beeper to sound. You can select one of the following choices:

- Off (beeper will never sound)

- Keys Only (pressing a key causes a beep)

- Alarms Only (when an alarm is activated)

- Keys & Alarms (beeper will sound when a key is pressed

or an alarm is activated)

After selecting the Beeper option from the Setup menu, use the up/down arrow to highlight the desired choice and press ENTER.

Page 77

17.Clear Memory This option allows you to clear one of the following data

sets from MobileMapper Pro’s memory:

- Track history: This feature is disabled in MobileMapper

Pro

- Wpts/Routes: Will clear all waypoints and routes from

memory

- Routes: Will clear all routes from memory

- Reset default: Will reset the receiver by restoring all fac-

tory defaults

- All: Will clear all memory

After selecting the Clear Memory option from the Setup menu, use the up/down arrow to highlight the desired choice and then press ENTER. MobileMapper Pro will ask you to confirm your choice. If you have selected All, MobileMapper Pro will then shut off. The next time it is turned on, it will prompt you that it needs to be initialized.

18.NMEA This option allows you to select the NMEA message that

will be output from MobileMapper Pro. Your choice will depend on which message is needed by the device connected to MobileMapper Pro:

- V1.5 APA: Autopilot Sentence “A”

- V1.5 XTE: Crosstrack error according to NMEA0183

V1.5

- V2.1 GSA: Standard GPS position message according to

NMEA0183 standard in version 2.1. The GSA message strings include GGA positions - the most commonly sought NMEA messages. If you have any doubt as to which NMEA option to select, the GSA option is usually what you want.

After selecting the NMEA option from the Setup menu, use the up/down arrow to highlight the desired choice and then press ENTER.

Page 78

Default: No protection

19.Baud Rate This option enables you to check or set the baud rate of

the data being sent out from the MobileMapper Pro’s output port. The possible choices are: 1200, 4800, 9600, 19200, 57600 or 115200 baud. The default baud rate is

4800. If you wish to manually set the Baud rate, select the Baud

Rate option from the Setup menu, use the up/down arrow to highlight the desired choice and then press ENTER.

The MobileMapper Transfer utility automatically sets the Baud rate to 115200 - the maximum speed of data transfer. However, the maximum Baud rate allowable for updating receiver software is 19200. You must select this rate, or lower, prior to updating.

Whenever you attach a MobileMapper Pro to an external source of real-time differential corrections, you should check that both the GPS and the beacon receivers are set to the same Baud rate.

20.Power Key This option allows you to change how the PWR button

operates in turning MobileMapper Pro on or off. Two choices are possible:

- No protection: this is the normal case of use. With this

option enabled, you will have to press the PWR button to turn MobileMapper Pro on. You will press the PWR button again to turn MobileMapper Pro off.

- On/Off protected: To turn MobileMapper Pro on with this

option enabled, you will have to press and hold the PWR button until the first screen is displayed. To turn it off, you will have to press the PWR button, and then press the ENTER button before the power off timer is done.

After selecting the Power Key option from the Setup menu, use the up/down arrow to highlight the desired choice and then press ENTER.

Page 79

21.Simulate This option allows you to set the simulator. It shows you how

MobileMapper Pro uses its various functions based on a simulated journey. The simulator is useful for learning or demonstrating MobileMapper Pro’s GPS functions when indoors and there is no GPS reception. When the simulator is on, MobileMapper Pro quits normal operation to operate in the simulator mode. You can choose one of the following three options when you access the Simulate option:

- Off: Will turn the simulator off. MobileMapper Pro will

return to normal operation

- Auto: Will turn the simulator on. A predefined heading

and speed rate will be used.

- User: Will turn the simulator on. A user-defined head-

ing and speed rate will be used.

After selecting the Simulate option from the Setup menu, use the up/down arrow to highlight the desired choice and then press ENTER.

If you have selected User, MobileMapper Pro will then ask you to enter heading and speed data.

22.Post-processing This option allows you to enter the activation code needed

to enable the post-processing option in the receiver.

Page 80

23.Language This option allows you to select the language that

MobileMapper Pro will use to display text. TIP: If you accidentally set the language to one you cannot read and want to get back to the Language Select screen,

follow these instructions. Press NAV until the Satellite Status screen is displayed and press MENU. Select the sixth item in the list and press ENTER. Press the up arrow once and press ENTER. You are back at the Language Select screen.

Delete Files

This option allows you to list the job files and feature libraries stored in memory. Use the up/down arrow to scroll through the list.

A symbol is placed before each filename. The meaning of this symbol is as follows:

> Indicates that this file is the current file into which data is being recorded + Indicates that the file has not yet been downloaded from the handheld

- Indicates that the file has been downloaded from the handheld.

Pressing ENTER will display the File Info dialog box showing the name, size and creation date for the job file you have highlighted in the list.

You can delete this file by pressing ENTER again (Delete field already highlighted) or you can come back to the job file list by pressing ESC.

Page 81

About the Format Card

option:

We recommend you

format all new SD

cards or SD cards used

previously in other soft-

ware applications.

Some SD cards are

configured with non-

standard file formats.

This can make the

cards unreadable.

Card Utilities

This option allows you to access the following functions:

- Save WP/Route: Allows you to save the waypoints and

routes you create with the handheld during your field operations. When using this function, you save your waypoints and routes in a separate file of the MMW type. For the sake of clarity, please use the “MMW” extension when naming this file.

You can then download this file to your office computer using the MobileMapper Transfer utility and then import it into the open job, in MobileMapper Office, using the File>Import function.

- Load WP/Route: Allows you to choose the waypoint file (an

MMW file) you wish to display on the Map screen. MMW files are created on the handheld when you upload jobs in which waypoints (and routes) have been defined.

- Format Card: This command allows you to format a blank

SD card or reformat an already used SD card. When selecting this function, a message warns you that this operation will delete all the data contained on the SD card. Select Yes to confirm this choice or No to escape.

- Test Card: Gives information on the SD card installed in the

handheld (format, size, status, number of files, bad clusters, free memory space). A Scan button is also available to let you scan the SD card in search of bad clusters (this operation takes a while...).

Connection to

Mounting Cradle

Direct Connection to

MobileMapper Pro

About...

The About... screen displays the current status of your MobileMapper Pro. Using the About... screen you can see the serial number of the receiver, the version of software, the version and memory size of the base map, the number of detailed maps you may have installed and their total memory, and how much free memory is available.

Using the Serial Cable

The serial cable is used in two different cases:

- When you want to connect MobileMapper Pro to the PC to upload/download data using MobileMapper Office.

- When you want to connect MobileMapper Pro to an external source of differential corrections.

The serial cable can be connected to MobileMapper Pro in two different ways:

- Direct connection to MobileMapper Pro: Using the attachment screw that is attached to the plug, tighten into the back of the receiver.

- MobileMapper Pro mounted to a vehicle mounting bracket: Place the receiver in the cradle, bottom end first. Snap MobileMapper Pro down until the release latch locks it in place. Attach the cable through the opening in the back of the mounting cradle. It is not necessary to tighten the attachment screw to the receiver, although you may do so for added security.

If your computer does not support serial communications, you will need to:

- Purchase a serial-to-USB converter to go between the serial cable and your PC

- Purchase an SD card reader with USB port (see next page).

Page 83

Using the SD Card

SD Card Location

As explained earlier on page 4, the SD card is located in the battery compartment. You need to open the battery compartment door and remove the two batteries to have access to the SD card slot.

When logging data, remember to close any open feature and then the job before removing the batteries.

Inserting an SD card

- Hold the SD card with two fingers with the label facing up. Place the top of the SD card in the channel provided in the battery compartment. Carefully push the SD card towards the top of the unit until you feel it lock into place. Do not force the SD card.

- Reinstall the batteries into the battery compartment. Be sure to observe the proper polarity.

- Replace the battery compartment door.

- Turn on the MobileMapper Pro unit.

Removing an SD card

- Close any open job and turn the receiver off

- Remove the battery door and then the 2 AA batteries

- Push the card slightly towards the top of the MobileMapper Pro. You will feel a slight click which is the locking mechanism disconnecting and then you will feel the SD card pushing against your finger. Allow the SD card to slide back towards the battery compartment. Now carefully continue to slide the memory card out of the channel it is in and lift it out.

Page 84

Downloading GIS Data Using an SD Card Reader

SD card readers are generally attached to PC computers through USB, a faster communication protocol than the conventional RS232 serial line used between the handheld and the PC running MobileMapper Office.

If your office computer is equipped with an SD card reader, you can significantly reduce the time required to download your field data to MobileMapper Office by removing the SD card from the handheld, inserting it into the SD card reader and downloading your field data from the SD card inserted in the reader. Once the download is complete, you can put the SD card back into the handheld.

Note: It is very important that you use only MobileMapper Office to transfer any files to or from a MobileMapper Pro receiver's SD card - both when the card is inside the receiver or inside a card reader. (The only exception is when you use Magellan MapSend to upload background maps or waypoint/ route files to the receiver.) MobileMapper Office processes some types of data files, such as background maps and postprocessing job files, during transfer. Other transfer utilities such as Windows Explorer or ActiveSync are unable to process MobileMapper Pro data and the transferred files will be incomplete.

Naming Conventions for Rover and Reference Files (Post-Processing Option)

Suppose you have created a new job named “JOB1.MMJ.” You selected the post-processing job mode in MobileMapper Pro so that it records GPS measurement files in addition to JOB1.MMJ. The table below illustrates how these files will appear at various stages of the differential correction process:

Rover file seen on receiver JOB1.MMJ Rover file seen on MobileMapper Transfer’s left

b0001a04.34

The rover files with a B, D or E in the extension represent files with different GPS measurements all related to the original rover file. MobileMapper Office handles the information in these files automatically. But if you archive your files, you should include them in the archived directories.

The reference files that start with B, D or E are similarly handled automatically by MobileMapper Office but should be archived together with the rover files.

Reference files recorded by non-MobileMapper Pro receivers may have other naming conventions.

The latest release of

receiver software allows

you to define the full

set of 9 parameters

defining a map datum.

After pressing MENU

and selecting

Setup>Map

Datum>Primary/Sec-

ondary and “USER” in

the prompted list, you

now have access to two

different screens on

which these 9 parame-

ters are presented:

1st screen:

Delta A (meters) Delta F (X 10,000) Delta X (meters) Delta Y (meters) Delta Z (meters).

2nd screen (select Next> at the bottom of the 1st screen to access this screen):

Rotation X (sec) Rotation Y (sec) Rotation Z (sec) Scale factor (ppm).

Defining a User Map Datum

Whether you are in the office using MobileMapper Office, or in the field working with your receiver, the system lets you create the user map datum you need.

However you will not use the same methods in the receiver and in MobileMaper Office to define the semi-major axis and flattening for your user datum.

In MobileMapper Office, you will use the conventional way of defining a user datum, i.e. by entering the semi-major axis (a), the inverse flattening (1/f) and the other 7 parameters.

The method used in the receiver is different as it is based on the use of parameters ∆a (Delta A)and ∆f (Delta F) –known as the Molodensky parameters– instead of a and 1/f. The other 7 seven parameters are exactly the same as those in MobileMapper Office.

∆a and ∆f are defined as follows:

∆a (m) = a(WGS 84) - a(Local Datum) ∆f = f(WGS 84) - f(Local Datum)

Note that the flattening (f), instead of the inverse flattening (1/f), is used in the expression of ∆f. So we have:

---------------------------

∆f

-- -

WGS84()

Because the resulting ∆f is a very small quantity, it is multiplied by 10 000 to make it easier to handle. (The resulting value is closer to 1.) It is this value that you have to enter in the Delta F field on the MobileMapper Pro handheld screen.

Glossary

Attribute: A description item of a feature. Attribute value: One of the possible values that can be as-

cribed to a feature.

Base Station: See Reference Station. B-File: A binary MobileMapper Pro data file containing

GPS measurement data. Carrier phase data: Phase angle measurements for the 1575

MHz radio wave carrying the GPS coded messages. Using carrier phase data greatly improves GPS accuracy.

Datum: A mathematical definition of a surface from which coordinates of a given system are referenced.

D-File: A binary MobileMapper Pro data file created by field collection software and stored in the receiver.

DGPS: Differential Global Positioning System. Commonly used to refer to real-time differential correction techniques.

Differential Correction: The process of: (1) calculating how much to adjust GPS measurements to re-

duce the difference between a location's surveyed coordinates and the coordinates calculated by a GPS receiver that is kept stationary over that point; and

(2) the application of these adjustments to the GPS measurements recorded by any number of receivers within a few hundred kilometers of the "reference receiver."

Differential GPS: See DGPS. E-File: A binary MobileMapper Pro data file containing GPS

ephemeris data. Ephemeris Data: Information transmitted from a satellite

which allows the GPS receiver to determine the satellite’s position in space.

Export: Converting MobileMapper Pro data files to GIS Formats and writing them to any directory visible to the PC.

Feature: Any element located in the field that you wish to record for further uploading into a GIS database for example. A feature can represent a real object (streetlight, park, electrical transformer, etc.) or on the contrary, something invisible or impalpable (gas, noise level, dose of fertilizer, etc.).

Each new feature that you log in the field can only be an “emanation” or “offshoot” of one of the feature types described in the feature type library associated with the job in progress. The logging procedure will be different depending on the type of the feature you are logging.

Page 91

To log a feature: Means to save the characteristics of a

feature into MobileMapper Pro’s memory. The user is in charge of entering the description of this feature whereas the receiver is responsible for saving the GPS position(s) it has determined on this feature. To describe a feature: Means to give each attribute of the feature one of the prompted values for this feature.

Feature Library: A file containing all the feature types required for a given job. (In fact we should say “Feature Type Library”.)

Feature Type: An item present in a feature library. Each feature type is defined by a geometry type, a name, a certain number of possible attributes and the list of possible values for each attribute. There are four different geometries in feature types: point, line, area and grid.

Field: Any area on MobileMapper Pro’s screen dedicated to displaying the value of a parameter. Some fields are user-editable, some others are not.

Geographic Information System: A system of digital maps, data analysis software and a database of features, attributes and geographic locations.

GIS: See Geographic Information System. Global Positioning System: A system of satellites providing

worldwide coverage for positioning information. Although installed and maintained by the United States, the broadcast signals are available to anyone anywhere in the world.

GPS: See Global Positioning System GPS satellite geometry: The satellite distribution at a given lo-

cation. measured by the PDOP index GPS signal multipath: Occurs when the GPS signal arrives at

the antenna by a path other than a straight line. Multipath signals make the receiver think that a GPS satellite is farther away than it is and the resultant position is inaccurate.

Job file: File containing a feature type library and a collection of features that grows as you log new features in the field with this job file open. All the features in the job file necessarily “originate” from the feature types present in the job file’s feature type library.

Nesting: This word is used to describe a feature that you are logging whereas another feature is already being logged.

PDOP: Positional Dilution of Precision. An accuracy factor derived from the geometry of the constellation of GPS satellites used to calculate a position. In general, the more widely distributed the satellites are in the sky, the greater the accuracy. In general, PDOPs less than 10 are good.

Page 92

Post-processing: Differential corrections applied to GPS posi-

tions in a PC - after both rover and reference data are logged and downloaded. Post-processing is slower but more accurate than real-time differential correction.

RTCM: Radio Technical Commission for Maritime Services. Commonly refers to a format of real-time DGPS format.

Reference Station: A stationary GPS receiver logging, or broadcasting, data from a known point. The data is used for differential correction. Reference Station is synonomous with Base Station.

RINEX: Receiver Independent Exchange Format. A “universal” GPS measurement data format designed to allow compatibility b tween different brands of GPS receivers.

Shapefile: A set of GIS files invented by ESRI but published as an open file standard readable by most GISs. A shapefile consists of a map file (SHP), a file containg feature descriptions (DBF), a file relating the map locations with the feature description (SHX) and sometimes a file containing coordinate system information (PRJ).

Waypoint: A pre-determined coordinate point to which a GPS receiver can navigate. GPS receivers can also log waypoints in the field for later navigation. GPS for GIS receiver have largely replaced waypoints with point features.

WGS-84 coordinate system: World Geodetic System, 1984. The coordinate system is used by GPS receivers for computing their positions.
