June 2004 TargetPro™ User's Manual

Chapter 1: Overview of the Software

1.1 Software Architecture

1.1.1 What is TargetPro?

TargetPro is a software module included with Isis sonar from Triton Elics
International, Inc. TargetPro is also sold as a separate, standalone utility.

If you have the Isis Sonar software (also from Triton Elics International), you
can use TargetPro to take snapshots of selective areas of your data imagery
that may be of interest to you. When TargetPro takes a snapshot of an
image, TargetPro also logs the quantitative data (geocoding, contact
mensuration) associated with the original data imagery from which the
image came.

You can then save these small images as files independent of the original
data imagery. Furthermore, you can then recall the image in Isis without
having to play back the entire data imagery that contained the selected
image – or you can have Isis play back the image in the larger context of
your data imagery, in case youwant to see the area surrounding the
selected image.

Even if you don’t have Isis, you can still use TargetPro to view and modify a
wide variety of images, including images that were created by someone else
who did have Isis. Finally, you can run TargetPro from DelphMap as a utility
for viewing and modifying files known to TargetPro.

1.1.2 What File Types Can TargetPro Read?

TargetPro can open (read) these file types:

• Contact (TEI proprietary *.CON files)

• Target (TEI proprietary *.TGT files)

• ESC image (*.TIF or *.TIFF files, with Tag 270 information in them)

• Pulse Code Modulation image (*.PCM, which are compressed ESC

image files)

• Joint Photographic Experts Group (*.JPEG and *.JPG files)

• Compuserve Portable Network Graphic (*.PNG files)

Chapter 1: Overview of the Software 1

June 2004 TargetPro™ User's Manual

• Microsoft Windows Paint (*.PCX files, which support color as well as
black and white)

• Microsoft Windows Bitmap (*.BMP files)

• Microsoft Windows Metafile (*.WMF files)

• Enhanced Metafile (*.EMF files)

1.1.3 What File Types Can TargetPro Write?

TargetPro can write (save) files into many file fortmats:
LEAD (1,8,24); JPEG (8,12,16,24); CALS 1-bit; Cserve PNG (1,8,24);

DICOM DIC (8,16,24); FAX (raw); EPS; EXIF; FPX (8,24); GEM 1-bit; GIF
(1-8); IOCA; MODCA (Raw IOCA); Mac PICT (1,4,8,24); MacPaint 1-bit; MS
FAX (AWD); MS Paint; OS/2 BMP (1,4,8,24); PCX (1,4,8,24); PSD (1,8,24);
SUN Ras (1,4,8,24,32); TGA 8,16,24,32); TIF (1-8,12,16,24,32); Win BMP
(1,4,8,16,24,32); Winfax; WMF (8,24); EMF (8,24); WPG (1,4,8); Win lco
(1,4,8); Win Cur 1-bit.

In the preceding list, the numbers in parentheses are the number of bits
supported for the named formats. Note, however, that TargetPro cannot
save PCM images as PCM images; that format can only be saved in
TargetPro as a non-PCM format file, such as TIFF.

1.1.4 What Formats Are Best for Exporting?

If you’re going to export an image from TargetPro and then use that image
in another application, you may want to save your image in a format that
offers the most support in the application that will receive the imported
image. At present, the best formats for saving TargetPro images to be used
in other applications are (in alphabetical order):

• BMP (24-bit)

• GIF (8-bit, 89a non-interlaced)

• JPG (24-bit progressive)

• PCX (24-bit, version5)

• PSD (24-bit PhotoShop file)

• TIF (24-bit)

The 24-bit formats are the only ones to support exporting the image in color.
All formats other than 24-bit will be in gray scale.

Note: The 24-bit TIF and BMP file formats are lossless. This is desirable,
since lossless formats retain all information even if you later compress or
enlarge the image.

Chapter 1: Overview of the Software 2

June 2004 TargetPro™ User's Manual

1.2 System Requirements

You need the following:

• A Pentium-class personal computer running Windows NT,
Windows 2000, or Windows XP.

• At least 32 MB of RAM.

• A software license from Triton Elics International to use the product. (The

license comes with TargetPro when you buy it.)

• A hardware dongle that has been programmed to recognize TargetPro.

• A computer monitor capable of displaying true 24-bit color images

(potentially 16,777,216 colors.) You could use a monitor that supports
fewer colors, but the results won’t be as good as they would be on a
monitor that can support 24-bit color images. Also, so that you can see
all of the application’s working area, your monitor must be set to at least:

 1280 X 1024 pixels if you are using large fonts, or
 1152 X 864 pixels if you are using small fonts

Before you can use TargetPro, you must install the TargetPro software using
InstallShield, and you must attach a properly configured dongle to your computer
to access the program.

1.3 Software Installation

Typical software installation CD will contain folders like the ones depicted in the
Windows Explorer layout. (See the figure, “Typical listing of TEI software
installation folders’.)

Chapter 1: Overview of the Software 3

June 2004 TargetPro™ User's Manual

Figure 1. Typical listing of TEI software installation folders.

TEI software is compatible with Windows NT 4.0, Windows 2000, and Windows
XP. The following notes will help you achieve a smooth installation of the
software.

• Please exit from all other applications before running any of the
installation programs.

• You will not be able to complete the installation on an NT4.0 or
Windows 2000 system if you do not have administrator’s rights. All Isis
“black boxes” ship with a user name Isis. In this case the Isis user
name has administrator’s rights and does not require a password.

Chapter 1: Overview of the Software 4

June 2004 TargetPro™ User's Manual

• Each application is installed by browsing to the appropriate folder (for
example, Isis5.50 Install) on the CD and double-clicking on the
SETUP.EXE file found in that folder.

• TEI recommends that if you have more than one hard drive, you install
the software on the second (usually the D:) drive, using the default
folder names on the CD. You will be given the option to select any drive
during the setup process, select the Custom option and change the
drive letter.

• The first installation on an NT4.0 system requires a re-boot during the
installation; however, this only occurs for the first installation. Under
Windows 2000 and Windows XP, no rebooting is necessary
installation process. However, you

must reboot the system after

installing under Windows NT 4.0.

• For each application, a number of sample data files can be optionally
installed. These files will reside in a subfolder called Demo Files within
each application’s main folder. These special files can be played back
or processed by the relevant TEI applications without a TEI sentinel
being installed. If no sentinel (dongle) is attached, a message displays,
indicating either that a sentinel was not found or that the sentinel is
damaged. However, you can still play back the sample files that come
from the CD.

• In order to run the software in acquisition mode, or to play back or
process other files, you will need a TEI sentinel attached to the LPT1
printer port. Contact TEI if you need a sentinel.

• If the operating system is Windows NT 4.0 or Windows 2000, you will
need to install a sentinel driver. The driver is included on the CD in the
Sentinel folder; a text file, with installation instructions, is in that folder.
The driver is

not required under Windows 95 or Windows 98.

• In the case of Windows NT 4.0, Service Pack 5 (or higher) needs to be
installed. Service Pack 5 is on the CD.

• The TEI manuals that are installed with the software are in Adobe
Acrobat PDF format. Acrobat Reader software (required to read the
PDF files) is also on the CD.

• The CD has a number of other folders containing drivers and
applications that could be required; each folder has a text file with more
information.

• To remove the software, use the Add/Remove Programs utility in the
Windows Control Panel collection of utilities.

• The installations make two changes which are not restored when the
programs are removed using Add/Remove Programs. They are:

during the

Chapter 1: Overview of the Software 5

June 2004 TargetPro™ User's Manual

 The addition of a folder called [TEIdlls] in the Windows, Win95 or

WINNT folder, and

 a modification to the PATH environment variable which adds the

[‘TEIdlls] folder to the PATH. The [TEIdlls] folder can be safely
deleted after all TEI software has been removed.

1.3.1 Installing a Hardware Dongle

A hardware dongle comes with TargetPro. The dongle permits TargetPro to
run after the software is installed.

To install the dongle, plug in the male end of the dongle to the female end of
a serial port on your computer.

1.3.2 Installing TargetPro

Triton Elics Int ships TargetPro with a utility used to install the product for
you. From the distribution medium made available to you from Triton Elics
Int, find the file called
install utility InstallShield. Respond to any InstallShield prompts, as may be
needed; let InstallShield guide you in the installation. When InstallShield
finished, the installation is complete, and TargetPro is ready to run.

setup.exe and double-click it. The system runs the

1.4 Upgrading to New Releases of Software

If you already have a version of the software that you wish to upgrade on your
system you will see a dialog box inviting you to modify, repair, or remove the
software you intend to install. See the figure, ‘Modify, Repair, Remove choices
during installation’ for an example of this kind of dialog box.

Chapter 1: Overview of the Software 6

June 2004 TargetPro™ User's Manual

Figure 2. Modify, Repair, Remove choices during installation.

You will need to remove the old version of the software before you will be
permitted to install the new version. To do so, enable the Remove button in the
dialog box and click Next. You can then install the new version by rerunning
setup.exe As noted above, some items are deliberately not removed during the
uninstall process; doing so can cause problems. If necessary, manually delete
the \TEIdlls folder, but only do this if you are going to re-install all TEI
applications.

Important Note: The Windows Installer will fail to uninstall the software if
the operating system has been upgraded from (for example) Windows 98 to
Windows 2000 after the TEI applications were installed. If you want to
upgrade your operating system, uninstall the TEI programs first, and then
re-install the TEI programs after the upgrade.

Chapter 1: Overview of the Software 7

June 2004 TargetPro™ User's Manual

Chapter 2: Using TargetPro

If you’ve installed the TargetPro software and have it running, you can use it to
open CON (contact) or TGT (target) fields, enhance them, and save the changed
files. This chapter explains how to do that.
You can then save these small images as files independent of the original data
imagery. You can then recall the image in Isis without having to playback the
entire data imagery that contained the selected image – or you can have Isis
playback the image in the larger context of your data imagery, in case you want
to see the area surrounding the selected image.

2.1 Running TargetPro

You can run TargetPro in a number of ways, shown next. Choose a convenient
method.

To run TargetPro, double-click on the TargetPro icon in the Triton group
(Microsoft Windows), or

• From Isis, configure for TargetPro availability (Tools → Target Setup…),

and then double-click the left trackball button while imagery is scrolling in an
Isis waterfall window to put a contact in the TargetPro working window.

TargetPro runs and displays its initial screen (Figure 3). Moreover, if you have
run TargetPro before, TargetPro remember the overall size and position of the
application window as it was when you last used it.

Chapter 2: Using TargetPro 8

June 2004 TargetPro™ User's Manual

Figure 3. Initial screen (empty) after first running TargetPro.

Because you have not yet opened a file for TargetPro to display, the Main
Working Area of the initial TargetPro screen, as well as any smaller child
windows that may be present, are empty of information. See ‘Understanding
TargetPro’s Windows’ for an explanation of the various parts of the application’s
overall window.

2.2 Opening a File

As noted earlier, you can work with any file types in TargetPro:

• Contact (TEI proprietary *.CON files)

• Target (TEI proprietary *.TGT files)

• ESC Image (*.TIF or *.TIFF files, with Tag 270 information in them)

Chapter 2: Using TargetPro 9

June 2004 TargetPro™ User's Manual

• PCM Image (*.PCM, which are compressed ESC image files)

• Joint Photographic Experts Group (*.JPEG and *.JPG files)

• CompuServe Portable Network Graphic (*.PNG files)

• Microsoft Windows Paint (*.PCX files, which support color as well as

black and white)

• Microsoft Windows Bitmap (*.BMP files)

• Microsoft Windows Metafile (*.WMF files)

• Enhanced Metafile (*.EMF files)

Those are the only file types that can be opened in TargetPro. If your contact
(CON) or target (TGT) files have been saved as digitized lines and/or polygons,
then TargetPro will display them that way.

To open a file TargetPro can recognize, do any of the following:

• From TargetPro’s main menu, choose File→Open,

• Press <CTRL>+<O>,

• Press [Insert],

or

or

or

• On the taskbar click the Open icon:

Any of those actions displays a standard Windows-based dialog box where you
can specify a file to pen. A typical file opened in TargetPro looks like the sample
shown in Figure 4.

Chapter 2: Using TargetPro 10

June 2004 TargetPro™ User's Manual

Figure 4. Typical file opened in TargetPro

After a file has been opened, the original list of menu items (File, Edit, Tools,
View and Help) expands to include two additional menu choices: Object and
Window.

2.3 Understanding TargetPro’s Windows

Initially TargetPro displays these windows and working areas:

• the Pan window

• the Display-Only Properties window

• the main display area for viewing opened files

Chapter 2: Using TargetPro 11

June 2004 TargetPro™ User's Manual

• the Cursor Status window

• taskbar icons

• Status Bar

In the taskbar area, all icons except for the Open icon and the About icon are
grayed out and unavailable until you open a file in TargetPro. All icons are
explained in “Icons on the Taskbar”.

If you double-click on any of the windows (except for the main display area), the
system displays the windows’ title bars and reveals their identities (Figure 3).
Note that the windows still lack information in them because you have not yet
opened a file in TargetPro. The two windows (Pan and Display-Only Properties
windows) are explained later on.

The Status Bar, where on-going and current status is displayed, is a narrow strip
at the bottom of the TargetPro window (Figure 3).

2.3.1 Repositioning displayed child windows

To reposition a displayed child window, double-click in the child window to
expose the windows title bar. Then, click in the title bar and drag the
window to the new position.

To return an undocked window to its original position, double-click in the
child window and the window moves back to its initial position.

All windows except the Main Display Area are child windows of TargetPro.
You can close or open the child windows from the View menu listed above
the Taskbar icons. The Main Display Area is not redockable (movable).

The individual windows are:

Pan Window. The black window near the upper left corner is a thumbnail

window for the currently active, opened TargetPro image, if any is present.
This window is known as the Pan Window. See ‘Pan and Display-Only
Properties Windows’ for more detailed information on this window.

Display-Only Properties Window. This child window contains four

independent controls for adjusting an image’s brightness, contrast, gamma,

and threshold. See ‘Pan and Display-Only Properties Windows’ for more
detailed information on this window.

Cursor Status Area. The rightmost area contains three panels of attribute

fields that may show information when you open a file in TargetPro,
depending on the type of navigation data and other attributes that may have
been present in the opened file prior to opening. Within the Cursor Status
Area, information is arranged in three panels:

• Cursor Panel

• Target-Debris Panel (or Target – Not Classified, if your opened file is not

a target or contact type of file)

• Towfish Panel

The fields in these three groups are explained in Table 1.

Status Bar. When you open a TargetPro file and that file has the active

focus, text identifying key properties of that file (such as file name, number
of pixels in the x and y axes, file size, zoom level, etc.) appear here.

Chapter 2: Using TargetPro 13

Attribute Field Name and Explanation

Date: This is the Julian date the data were recorded.
Time: This is the time (hh:mm:ss) the data were recorded.
Latitude: These are the degrees north or south of the equator
as measured from the point of the trackball pointer when the
contact was made. The heading of this field changes to
Northings if the data were recorded that way.
Longitude: These are the degrees east or west of the meridian
as measured from the point of the trackball pointer when the
contact was made. The heading of this field changes to
Eastings if the data were recorded that way.
Ping: The nth consecutive ping (shot) of the recorded data at
the point where the trackball pointer was placed when the
Target contact was created.
KP: Kilometers of Pipe or Kilometer Posting. Measure of
distance along a pipe or pipeline route.
Range: This is the range from the towfish to the current point,
either the cursor or the object being measured.

Distance: This is the distance between the end-points of the
rubber-band line drawn from one contact to another.
Pixel: This displays the x (x-axis coordinate), y (y-axis
coordinate), and z data (intensity) of any pixel in the displayed
image.

Target –
Debris
(or Target – Not
Classified for
non-contact
files)

Latitude: Degrees north or south of the equator. This changes
to Northings if the data were recorded that way
Longitude: Degrees east or west of the meridian. This changes
to Eastings if the data were recorded that way.
Range: This is the range from the towfish to the current point,
either the cursor or the object being measured.
Width: Across-track distance of mensuration.
Length: Along-track distance of mensuration.
Height: Height is how far an object stands above the seabed.
Height computation uses the length (width in across-track) of
the shadow, distance of the object from the towfish, and the
towfish altitude.
Depth: This is the vertical distance the target is from the sea
surface.
Pings: Number of pings traversed by a drawn line. Also see
‘Number of Pings’.
Beam W.: Width of the beam at a specific range distance. This
parameter is updated with any length measurements. Also see
‘Beam Width’.

Target –
Debris
(or Target – Not
Classified for
non-contact
files,
cont’d)

L.Rot. (Length Rotation) Rotation angle of the length line
relative to a horizontal line. Angle is computed from a
horizontal line. Also see ‘Length Rotation’ on page 28.
L.Adj. (Length Adjust) is the difference between the length of a
line and its along-track length. In the case of a slanted line,
length is derived from the vertical component of the line, and
the L.Adj. measures the difference between the length of the
line and the along-track length. Also see ‘Length Adjust’.
W.Adj. (Width Adjust) is the difference between the length of
the line and the across-track width. Also see ‘Width Adjust’.
W.Rot. (Width Rotation) Rotation angle of the width line
relative to a horizontal line.

Towfish

Range: This is the range from the towfish to the current point,
either the cursor or the object being measured.
Speed: This is the towfish’s speed.
Altitude: This is the vertical distance the towfish is from the
seafloor at nadir.
Depth: This is the vertical distance the towfish is from the sea
surface.
Note: altitude + depth = total water column depth

Heading: With respect to standard compass bearings, this is
the direction, in decimal degrees, in which the towfish is
pointed.
Beam: This is the horizontal beam angle of the sidescan sonar.

2.4 Icons on the Taskbar

Immediately underneath the menu list is the TargetPro taskbar of icons. They
are shown in Figures 5 and 6. Several of the icons have to do with operating the
cursor, or trackball pointer in the program. Additional icons are associated with
the Measurement Tool and the Zoom Tool. Tool Tips are attached to each icon,
and each icon has a menu equivalent in the Tools menu.

For space reasons, the icons appear in this book in two rows. In the TargetPro
program, the icons are laid out in a single row. Most icons are grayed out until a
contact image is opened. All icons become visible when an image is opened and
as long as the Cursor Tool icon remains clicked. (The Paste icon will be grayed
out if there is nothing in the Windows Clipboard.) All choices within an icon
group are mutually exclusive; you can perform only one function at a time from a
group. Icons in Groups Two, Three and Four are unique to TargetPro. All the
icons are explained in the next few tables.
