Introduction
The Leica Geosystems GS20
The Leica Geosystems GS20 PDM was conceived to provide
the GIS community with a GPS data collection device that
combines the simplicity of a recreational GPS handheld with
the power and flexibility of a professional grade mapping
system. The Leica Geosystems GS20 represents a true
turnkey GPS/GIS mapping solution by integrating the GPS
receiver and antenna within the chassis of handheld data
collector. Add to this the built-in efficiency of Bluetooth
wireless technology and you only need add power and sky;
the rest is up to you.
Philosophy of Operation
• Data Collection is used for the initial recording and
attribution of points, lines, and areas.
• Data Management is used for the update of attribution
and geometry of an object; including relocation and
continuation of existing geometry
• Navigation is only used for the purpose of finding a known
location. Any update to the navigated object must be done
in Data Management.
• Utilities contains File Browser, Firmware Update and
Sensor Transfer
• Setup allows the user to configure software operation
settings such as GPS controls, Data Collection Quality
Control, external Interfaces, and Units and Formats, and
Languages.
• Status provide the user with information related to GPS,
external interfaces and the condition of hardware and
software.

1. Basic Operation
1.1 Batteries and Charging
Leica Geosystems GEB90, 7.2 volt, 2100 mAh Lithium-Ion
batteries must be used to power the Leica GS20 and WoRCS
equipment. Charge only with the Leica Geosystems battery
charger provided in the system.
WARNING:
The battery chargers are intended for indoor use only.
Use a battery charger in a dry room only, never
outdoors. Charge batteries only at an ambient
temperature between 10° C and 30° C (50° F to 86° F).
We recommend a temperature of 0° C to +20° C (32° F
to 68° F) for storing the batteries.
1.1.1 Calibrating the Battery
The Leica Geosystems GEB90 battery uses a microprocessor
to accurately monitor the battery status. To calibrate the
battery microprocessor, allow the Leica Geosystems GS20 to
rundown and automatically power off.
The Leica Geosystems GEB90 battery can be
)
referenced and ordered by Leica part number 724117.
The Leica Geosystems GKL24 Dual Bay Battery
Charger can be referenced and ordered by Leica part
number 731771.
Use only the Leica Geosystems batteries, chargers,
)
and accessories, or accessories recommended by
Leica Geosystems.

Basic Operation
1.2 Powering On the Unit
Press and release the Power Button located on lower left of
the keyboard. The unit will reply with an audible tone, then
proceed to a splash screen and then to the Main Menu.
Remember: Although the unit can power on without the flash
card, most functionality will not be available.
1.3 Icons
The Icon area is displayed to provide the user with current
information about the GPS and hardware.

Figure 1-1: Accuracy Indicator
1.3.1 Accuracy Indicator
The accuracy indicator is displayed once a solution is
calculated. The open sphere indicates that an autonomous
position has been determined and the bullseye target
indicates a DGPS solution. Additionally information provided
in the text include horizontal and vertical qualities, as well as
PDOP.
12
Basic Operation
1.3.2 Stop and Go Indicators
When a static position is located, such as a point or a node (in
a line or area), the stop and go indicator is displayed as a
tripod. Once the icon returns to the walkingman, the user can
proceed to the next collection point.
1.3.3 Satellite Indicator
The satellite indicator provides text based information
including the satellite tracking angle, the number of satellites
visible (according to the almanac) and the number of satellites
currently tracked.
(Satellites Tracked / Satellites Visible)
1.3.4 Differential Corrections
When differential corrections are received and interpreted, the
differential icon appears. If the correction is lost after 1/3 of the
selected age (see 9.8.1 "Real-Time"), an exclamation point
will appear in the lower left hand corner of the window. If it is
still absent after 2/3 of the selected age, an additional
exclamation mark will appear. If corrections are lost beyond
the selected age, a third exclamation will appear and the icon
will then disappear.
1.3.5 Memory Card Status
The memory card status icon provides a graphical
representation of the percentage of the compact flash used.
1.3.6 Battery and Time Indicators
The battery and time indicators provide information about the
current status of the onboard battery and the current time
obtained by satellites.
• Because the Battery indicator is based on a
microprocessor in the Lithium Ion battery, only the onboard
battery status can be provided in percentages.
• Because the Leica Geosystems GS20 does not rely on
internal batteries for clock function, time is only displayed
when 1 or more satellites is tracked.
Leica GS20 Field Guide-1.1.0en

Basic Operation
1.4 Button Functions
1.4.1 Alpha Numeric Keys
Keys 1-9 represent the alpha numeric entry keys of the GS20.
Similar to a cellular phone, buttons 2-9 contain alpha
characters; by pressing the key continuously, all characters
on that key will be scrolled. The selection of a character can
be made by either selecting a different key, or waiting for the
2 second time-out. Special characters can be found on the
decimal key on the lower right of the keyboard.
1.4.2 Power Key
To power the unit on, the power key needs only to be pressed
and released. The unit will then respond with an audible tone,
followed by the splash screen.
Time to splash screen may depend on compact flash
)
size and the amount of data on disk.
While in operation, the backlight can be turned on with a
button press of less than 3 seconds.
If the power key is depressed and held for three seconds, the
unit will power down and give a message confirming the
power down and saving of data.
Figure 1-2: Leica GS20 Keypad
Remember: Depressing and holding the key acts like
multiple key presses.
Multiple functions: Keys 3 and 9 have been provided with
additional functionality. In a map display, 3 and 9 function as
zoom keys; in a table, 3 and 9 function as page up and page
down.

1.4.3 Enter and Escape
Similar to standard Windows’ controls, the Enter key is used
to either accept a choice or advance an action. The Escape
key functions both as a back key, to escape from a current
screen; as well as a backspace in edit fields.
1.4.4 Cursor Keys
Cursor keys are found on the face and the side of the unit; the
side cursors function exactly the same as the up and down
cursor on the face. If held down, the cursor key will
automatically speed up, such as in the map display, table, or
edit field. Because the cursor key is so integral to control and
entry, its functions vary in different controls.
1. Menus: Left and Right function as home and end.
2. Edit Fields: Up and Down function as home and end.
3. Check Boxes and Radio Buttons: Left/Right toggle makes
a field selection.
4. Combo Box and Spin Controls: Left and Right scroll
selections.
5. Map: Controls the cursor
1.4.5 Menu Button
The Menu key is the prime key in the Leica Geosystems GS20
user interface. Not only can Menu bring you quickly back to
the Main Menu to load the paging queue and select new
application, it also opens the context menu which contains all
of the high level controls for the unit.
Leica GS20 Field Guide-1.1.0en
15
Basic Operation
1.4.6 The Main Menu
The Main Menu is the base level of the Leica Geosystems
GS20 user interface. The Main Menu can be quickly accessed
from an application by double clicking the Menu button. By
returning to the Main Menu in an open application, it is
possible to run several application simultaneously; this is
referred to as the paging function.
1.4.7 Paging
Because it is often necessary to access several applications
at once (e.g. data collection, navigation, satellite view, etc.)
Leica Geosystems has created the Power Paging function.
Power Paging allows the user to quickly and easily flip through
running applications in the order they were opened. To place
an application in the paging queue, simply open the
application from the Main Menu. To add an additional
application to the queue, double click Menu to return to the
Main Menu, then open a new application. The paging button
will then page through the open applications. To remove an
application from the page, simply Escape from the application
to the Main Menu.

1.5 Software User Interface
Table 1-2: Mapview Legend
1.5.1 Map Views
The map view is the common interface on which all main
applications are built. Data Collection, Data Management and
Navigation all contain a map interface that has similar controls
and are continuously updated, but have independent settings.
Zooms, filtering, selection, and autopan GPS are all unique to
each applications mapview.

17
Basic Operation
1.5.2 GPS Symbol and Zoom Controls
By default, an open mapping screen zooms to the full extent
of data in a job; however if no data exists, the map will be
centered on the GPS location (scaled to 1:20m) awaiting
collected data.
The map submenu contains zoom controls for
• Zoom In, Zoom Out, Zoom To Full Extents
• Center Cursor, Center GPS, Center Selected
• Autopan GPS
Remember: “3” and “9” function as zoom controls !
Remember: The mapview is only capable of displaying
12,000 nodes, being points or line/area
verticies. A warning will be issued at 9500
nodes, that the map will be discontinued. A final
warning will be issued before the map display is
turned off.
Tip: To minimize nodes in a job; consider streaming lines
and areas by distance or at a slower rate. An 8 hour
constant collection at a 5 second interval only produces
5760 nodes.
The map display can be turned off in the Job
)
Management Screen.
1.5.3 Context Menus
The context menu in the Leica
Geosystems GS20 functions
similarly to a Windows’ context
menu, however the right mouse
click is replaced with the Menu
button. When the Menu button is depressed, a list of choices
will be displayed based on the application and the actions
taken.
• Choices in the context menu can either be selected using
the cursor arrows (Left and Right being home and end) or
directly accessed via the number keys.
• To simplify submenus appear where common groupings
exist such as map control functions. The submenu is
denoted with a right arrow and is accessed via enter or the
number key. In some instances, sub-submenus exist.
Leica GS20 Field Guide-1.1.0en
18
Basic Operation
1.5.4 Tables and Filtering
Tables are used to display multiple attribute data that cannot
be directly edited. The table can be navigated by the cursor
keys (left and right being home and end) as well as the
overload keys 3
Two main types of tabular data found in the GS20 are
selectable and informative.
• Selectable fields allow the user to make a selection such
as choosing a Job or Codelist, and are usually identified by
a radio button (selectable circle). Additional options, such
as New, Delete, etc. usually exist in the context menu.
• Informative fields allow the user to view and manipulate
information about the tabled object.
Page Down and 9 Page Up.
Figure 1-5: Selectable Table
1.5.5 Filtering
In order to provide power and flexibility to the user, the Leica
Geosystems GS20 maintains separate filters for individual
tables and maps.
1.5.5.1 Map Filters
Map filters provide the user with the ability to hide or display
data in the map.
Map filters allow the user to discriminate data based on
• Feature Code (Layer name)
• Feature Name (Feature ID)
• Feature Type (Point, Line, or Area)
• Time of collection
• Waypoint Status (Flag as Waypoint (i.e. to be navigated to)
or Visited)
Similarly data can be filtered in a table for selection, edits,
clipboard function or changing the Waypoint status.
Leica GS20 Field Guide-1.1.0en
19
Basic Operation
1.5.5.2 Table Filters
Table filters allow the user to search for data based upon the
same criteria as listed above in map filters.
Once a table is filtered, the user can select from the filtered
table, or view the selected filters in the map view via the
context menu choice Table Features.
This differs from map filtering in that the data remains
)
displayed, but appears highlighted.
Leica GS20 Field Guide-1.1.0en

Basic Operation
2. Data Collection
2.1 Job Management
When Data Collection is opened, if no job is currently
selected, the user will be prompted to either “Open” an
existing job or create a “New” job to continue. If a new or
empty job is selected, the unit will prompt the user to attach a
codelist; otherwise the program will proceed to the Data
Collection map.
Figure 2-1: Job Management Screenflow
Figure 2-2: Job Management Screenflow
Tip: When you create a new job, you have the option of
attaching a Coordinate System and Geoid file with
creation of the job.
Tip: See 5. "Job Management" for more info

Data Collection
2.2 Background Files in the GS20
Often it is important for a user to see the location of they’re
current position and those Features they have collected within
a larger context. However, it is not always necessary or even
beneficial to have that data selectable. With the ability to
create vector background data, the GS20 can now:
• Attach larger vector reference files
• Use the same vector reference file for multiple jobs
• Reference multiple files to a job
• Reference previously collected jobs in an open job
• Only re-import collected or updated data
2.2.1 Overview
GS20 background files are graphic files that can be created in
GIS DataPRO, and are automatically created when job data
is collected in the GS20. The graphic file contains the file
extension qtr, which stands for quadtree; a method of spatially
indexing vector data. When a job is created in the GS20, a
graphic file of that same name is also created. From job
management, a background screen can be accessed,
allowing the user to reference other “background” graphical
data to the job. Background graphic files are for visual
reference only, and are not selectable.
2.2.2 Adding Background Files to a GS20 Job
To add a background Map, enter Job management, highlight
a selected job, and select “Background Maps” from the
context menu.
Figure 2-3: Background Maps
Leica GS20 Field Guide-1.1.0en
22
Data Collection
A status of available memory will be available to provide
information on how much information can be attached to a job.
Memory used in background files will affect the amount of
map data that can be collected, so be conservative in your
estimates.
A successful attachment will be shown in the Status column
and Memory Available will be recalculated.
2.2.3 Creating a Background File in GIS DataPRO
In order to create a graphic file in GIS DataPRO, it will be
necessary to first import the data into the GIS DataPRO
database.
Data that is added to GIS DataPRO with the +, or add
shapes cannot be converted into a graphics file.
To create the Graphics file, select “Create GS20 Graphic File”
from the Tools pull-down menu.
A dialog will prompt for a filename and path, with the default
being active. The user can select to create a background from
all data, or only selected objects.
Figure 2-4: Creating a background
2.2.4 Transferring a background File
To transfer a graphic file, open Tools / Sensor Transfer. Right
click on Sensors, and Add a Sensor. Under My Computer,

2.2.5 Viewing the Map
If all has gone according to plan, the graphic file will be
attached to the current job, and will be displayed in Map View
applications. Because the memory used by the graphic files
are not recovered during use, it will be necessary to reboot to
reclaim lost space once a background is detached from a job.
Figure 2-5: Viewing the Map
2.2.6 Turning off the background in the Map Display
Similar to the Filtering ability of layers and data types in a Map
View, Background files can be turned on and off. To turn off a
Map view, select the Map Filter from the Map context menu,
and press enter on the layer with the new Background Icon.

2.3 Code Management
Because the Leica Geosystems GS20 is designed for GIS
data creation and update, existing feature layer will be used
as a code template for each particular job. Additional codelists
can be attached to a job via Codelist Manager.
In order to protect database integrity, a consistency check is
performed when codelists are attached to a job. If the same
code occurs in both the feature table and the codelist, the job
feature data will be used.
Codelists can be attached and detached as well as created
and modified from the Codelist Manager in the MAIN menu.
2.3.1 Creating Codelists
What is a Code? Codes are used to describe objects of the
same type. The code in GIS DataPRO is equivalent to the
Theme in ArcView 3.2. Each code has it’s own type, with only
one type per code: point, line or polygon For example: Tree
(Point), Roads(Line), Parcels(Polygon).
A code contains attribute information that may be assigned to
the Codes (points, lines or areas) during measurement in the
field.
For example: Fire Hydrant (Code): Serial Number and Color
(Attributes).
A Codelist contains codes to be collected in a job, and is
attached to a job.
A codelist can be created in three ways:
1. Create your own codelist/code.
2. Copy another codelist/code from another project.
3. Import codes from existing shapefile.
Codelists are created in the Codelist Manager in GIS
DataPRO.

2.3.2 Using the Codelist Manager
1. Select Tools from the Main Menu.
2. Select Codelist Manager, this is the interface you will see.
Listed below are the steps for codelist creation. We will list
them here, and then look at each one in depth.

2.3.3 Steps for codelist creation
1. Create a Codelist in GIS DataPRO
2. Create Codes Unlimited codes in a codelist
3. Create Attributes Maximum 60 Attributes per code
4. Attach Map Symbology to each code in a codelist
5. Save codelist
6. Transfer a Codelist to sensor.

2.3.3.1 Step 1: Creating a new codelist in GIS Data Pro
1. Click on Codelist and select New Codelist
2. Type in name of the New Codelist.
3. Click OK.
Your new codelist is now created, highlighted and ready to be
populated.
2.3.3.2 Step 2: Creating Codes in GIS DataPRO
1. From the pull down menu choose new code
2. Create a new Code Name and Description
When a codelist is
)
created the first code is
always Waypoint and
cannot be changed!

2.3.3.3 Step 3: Creating Attributes
1. From the Attribute pull down menu choose New Attribute
2. Fill in the attribute name and properties.
3. The attribute Type can be Normal, Mandatory or Fixed
4. The attribute Value can be Text, Real or Integer
5. The attribute Value Region Can be None, Choice List or
Range
6. The Default Value can be typed in if None or Range was
selected in the Value region. It can be selected if Choice
List was used.

Facts About Attributes:
1. The Z attribute is reserved and cannot be changed.
2. The Z attribute contains elevation data
3. Maximum 256 characters per Choice List
4. Attribute names must begin with a letter
5. Limit the attribute names to 10 characters
2.3.3.4 Step 4: Display Attributes: Attaching Map Symbology
The display properties are used to display each feature in the
GIS DataPRO after data collection.
From the Code pull down, choose “Set Display Attributes.
The Codelist may now be saved with map symbology intact.

2.3.3.5 Step 5: Transferring Codelist to the Sensor
1. Open Sensor Transfer
2. Add Sensor
3. Browse to location where codelists are stored (default
location: C:\GDP_Data\Codelists)
4. Right click on codelist and select Send Files...
5. In the Send Files... dialog select the codes you would like
transferred
6. Select the appropriate COM port and select Codelist from
the File Type Choice
With your codelist now on the sensor, you are ready to attach
it to your job and collect GIS Data.

2.4 The Codelist and Occupation
2.4.1 The Job Codelist
If a job is new (i.e. does not contain any data), the user will be
taken to the code table; otherwise the user is defaulted into a
map view. From the mapview, you can enter features via the
context menu, or by just pressing Enter. From the code table
screen, the code template can be selected by using the cursor
or searching with the pop-up dialog (which opens with an
alpha numeric key.)
Figure 2-9: Data Collection / Job Codelist
2.4.2 Attribution
After a code is selected, press Enter to open the attribution
screen. By default the focus is on the Occupy button;
however, by using the cursor and Enter key, attribution values
can be entered. Additional occupation selections can be
accessed via the context menu.
2.4.3 Point Collection
Point collection is often as simple as entering attributes,
pressing Occupy and Save; however different user defined
quality settings can determine how the feature is collected
(see Setup/Data Collection.) In addition to direct locations, the
user can also choose from a list of point offsets.
