Welcome to Triton Perspective!

Triton Perspective™ is a new product line from Triton Imaging that takes advantage of the

latest in software technologies including: multi-core parallel processing, indexed cache files,
workflow wizards, XML project files, multi-resolution tiling, and dB-based rendering to
develop products that are fast, accurate, efficient, easy to use, and that provide the tools
necessary for a broad range of real-world marine applications.

Perspective Map™, a GIS-based mapping package, forms the foundation of Perspective by
integrating the Triton BathyOne™, MosaicOne™, TargetOne™, and SeaClass™ software
modules into a cohesive suite capable of processing, fusing, and displaying sidescan and
multibeam data. Each module is controlled from the Perspective Map environment via
common, embedded user-interface, tools, and displays. Perspective Map displays the output
from these modules as multi-layer, co-registered survey tracks, sidescan sonar images,
bathymetry DTMs, target icons and images, and seabed classification areas and boundaries.
These seafloor image data can be easily combined with other available geo-coded data such
as S-57 electronic nautical charts, coastline maps, and satellite or other GeoTIFF imagery as
required. Output of individual and fused data products in standard formats for processing by
third-party applications is supported.

BathyOne™ will process raw multibeam data
and combine it with vessel position, pitch, roll,
heave, and heading; tides; sound velocity; draft;
and other data to produce accurate corrected
bathymetry grid files. Total Propagated Error
(TPE) of the gridded data is calculated and made
available for review and display. Gridded results

are displayed as layers in Perspective Map along
with other survey data such as coastline vector maps, electronic charts, sidescan mosaics, etc.
A variety of display options are provided for bathymetry layers, including profiling, color­coding gridded data by depth, relief shading, and transparency adjustment. With these tools,
comparing recently collected bathymetry with other sensor data and historical data sets is a
simple and intuitive process.

ii | P a g e February 2011

MosaicOne™ makes the production of high quality
geo-registered sidescan mosaics a simple process.
Mosaic images of sidescan or multibeam backscatter
data are created by simply dragging and dropping raw
XTF data files into the Perspective Map multi-layer
map view. Processing options such as nadir delete,
far range clipping, and single-channel select, coupled

with a comprehensive set of navigation processing
tools, result in superior quality mosaics suited to specific application needs and collection
regimes. MosaicOne images are displayed in Perspective in correct registration with other
survey data such as shaded or color-coded bathymetry, electronic nautical charts, coastline
vector data, survey tracks, target icons, annotation, seabed classifications, etc. Data fusion is
facilitated by adjusting the transparency of mosaic images allowing visual comparison of
sidescan features with underlying data elements. Fine adjustments to line position are easily
made with the new Move Line feature and high-resolution waterfall displays of sidescan data
direct from source XTF files cab be invoked with point and click at any position on the
mosaic.

TargetOne™ is a collection of target
processing tools that enable the acquisition and
analysis of objects seen in the sidescan data.
Targets are acquired with point and click on a
sidescan mosaic displayed in Perspective Map
or from the raw sidescan data viewed in
Perspective's embedded waterfall viewer. The
TargetOne module displays target images and
provides for a variety of image manipulation
and measurement tools to facilitate object recognition and classification. Target positions are
recorded as icons displayed on the mosaic with easy access to any target by clicking on an
icon of interest. Object measurement tools are provided that exploit sonar parameters.
Output of target information is in standard XML format to support processing by other
applications.

iii | P a g e February 2011

SeaClass™ is an advanced seabed
segmentation/classification module that
automatically characterizes bottom types based
on statistical properties of sidescan mosaics or
multibeam backscatter imagery. SeaClass is
based on a multi-layer perceptron supervised
neural network. The classification procedure
consists of two stages: a learning stage and a
classification stage. Training is accomplished
by the operator selecting areas in the mosaic of differing bottom type (e.g. sand, rock,
mud, etc.). Training of the classifier neural network then proceeds thru an automated
statistical analysis of the selected samples and a characterization of each type. The
following classification stage is a completely automated process where the entire mosaic
image is segmented into the different classes. Results of the classification are displayed
overlain on the mosaic image with each area colored or optionally with vector/line
boundaries around each area. Output from SeaClass can be the DXF boundary vectors or
a GeoTIFF mosaic image with the displayed color-coded areas.

1.2 Information Displays

Perspective Map has four tab-controlled information displays in the upper left corner of the
software window, located to the left of the Map View and above the File Tree.

Cursor Tab: This the default display, which shows the cursor position and the map.

Measure Tab: Shows the results of measurements made in the map view.

Offset Tab: Shows the amount a sidescan line has been moved for feature alignment.

Contact Tab: Indicates the target capture size and next target number.

Custom Cursor: In addition to the 4 tabs of information, there is another cursor information

display below the File Tree for setting a custom cursor position display.

For Custom Cursor Tab details go to Section 1.4.

1.2.1 Cursor Tab

The cursor display is where position values can be viewed dynamically as the cursor is
moved across the Map View.

The current project projection is displayed in gray at
the top of this tab.

North and East, Lat and Lon display the current
cursor position in the Map View. It is updated as the
cursor moves.

The button beside 'Lat' and 'Lon' is used to change
the format of latitude and longitude from 'degrees
minutes decimal seconds' to 'degrees decimal
minutes' to 'decimal degrees'.

The button beside 'Depth' is used to change the depth value from meters to feet.

The slider button is used to change the Map View resolution from meter/pixel to cm/pixel.
Acts like a zoom.

1.2.2 Measure Tab

Selecting the 'Measure' toolbar button in Perspective map will switch the information

6 | P a g e February 2011

display to the 'Measure' tab to show the results of measurements made in the map view.

When using the 'Measure' tool, select a starting point on the map by left clicking on the spot
and holding the button down while the distance to measure is spanned. Once the end point is
reached, release the mouse button. The measurement results are displayed dynamically in the
'Measure' tab. Units are always in meters.

The following image shows the results of the most recent measurement:

Horiz. Dist.: the distance covered by the
measurement in the horizontal or "X" direction.

Vert. Dist.: the distance covered by the
measurement in the vertical or "Y" direction.

Distance: the direct distance along the line drawn
in Perspective Map.

1.2.3 Offset Tab

When a sidescan line is moved with the 'Move Line'
function (see topic for move line), the amount the line
was moved in order to align it with the rest of the
mosaic is stored in the cache file.

When a line is moved using the ‘Move Line’ tool, the
amount the line was moved will be displayed in the
‘Offset’ information tab as shown in the image to the
right.

For this line the total amount of displacement was

7.93m, with the horizontal (X) displacement of 3.12m and vertical (Y) displacement of

7.29m.

1.2.4 Contact Tab

Selecting the 'Contact Generation' toolbar button in
Perspective map will switch the information display
to the 'Contact' tab.

Size (in meters) indicates the size of the screen
capture to be made when a target is selected from

7 | P a g e February 2011

the Map View.

Contact Number is the number to be assigned to the next target selected.

Also shown is the 'Contacts Color Legend' to visually distinguish between the types of
contacts displayed in the Map View.

1.3 File Tree

The file tree organizes project layers by
grouping similar items. The layers can be
toggled on or off by clicking in the box next to
the layer. A green check-mark appears next to
the items in the map root that are displayed in
the Map View. The order the items are arranged
in the map tree dictates the display order in the
Map View.

1.3.1 Map Root Layer

Layers organized under the heading of Map
Root include:

 Annotation
 SeaClass
 Contacts
 Vectors
 Navigation
 Imagery
 Background

All layers in the File Tree can be toggled on/off by checking or un-checking the box next to
the layer. If a box is unchecked, all sub-layers will also be unchecked. Conversely, by

checking a box that is not already checked, all sub-layers will
also be checked.

The image above shows the basic File Tree structure and the
check boxes for toggling the display of that layer:

Right-clicking on ‘Map Root’ will bring up the following menu
for user-defined controls of the map root dialog.

8 | P a g e February 2011

Selection Color: Allows the user to identify the color which the selected line will change to,

in order to identify it as being successfully selected in the map directory

Collapse to Roots: Quickly collapse the tree to the major headings. A plus sign will be
assigned in front of those headings which have additional data in their hierarchy.

Expand All: Allows the user to quickly expand all directories within the map root. A
negative sign will be assigned in front of those headings which are fully expanded.

Open Project: Allows the user to open a project from the tree diagram. This has the same
functionality as the “File > Open Project” pathway.

New Project: Allows the user to create a new project from the tree diagram. This has the
same functionality as the “File > New Project” pathway.

Info: Gives the user a “Window” on the Project File contents. The project file has the file
extension .proj xml and is an XML file. Advanced users could edit this file directly using
any XML file editor.

1.3.2 The Annotation Tree

This layer includes information that is user-defined in the Map View. The annotation layer
has three sub-layers: Regions, Grid, and User.

The Regions layer provides one-click access to different preset map zoom levels that are
commonly used for quickly navigating around the Map View.

The Grid layer provides options for changing the projection grid color and resolution settings.

Text and drawing annotations made by the user are stored in the User layer.

1.3.2.1 Regions

Regions are predefined zoom extents that
are useful for quickly moving around in
the map window.

To add a region, zoom the map window
to the area that is to be considered a
region, right click on “Regions” and
select ‘Add Viewport’ as shown below

This is will give a user dialog window to

9 | P a g e February 2011

name the selected region.

A dashed outline will appear in the Map View
delineating the area as being selected. The
region name will appear as a node under the
‘Regions’ layer node.

Right-clicking on the region name gives the following options:

Color Settings: The user can change the color and characteristics of the outline, as well as
color, opacity, thickness and character of the line.

Rename: The name of the region can be changed by selecting “Rename…”

Move To Top, Move Up, Move Down: Allows the used to move the region up and down

within the region file tree node.

10 | P a g e February 2011

Remove: The region can

be removed by selecting
“Remove…”

Info: Allows the user to
view the datum/projection
and coordinates of the
region.

1.3.2.2 Grid Overlay

This is an overlay graph of the lines of
Easting and Northing, which are
automatically displayed in the Map View. It
can be modified in resolution and in color.

Right-clicking on the ‘Grid’ layer will give
the following options:

Resolution: Allows the user to change the resolution of the grid overlay to a user-defined
distance.

Color Settings: Allows the user to change the
color of the grid overlay.

Info: Allows the user to view the resolution,
datum/projection and coordinates of the grid.

1.3.2.3 User Annotation

Drawing tools are available under the Modality > Annotation menu or by selecting the 'Pen'
toolbar button. When annotations are created using the drawing tools, they appear in the
Annotation > User file tree menu.

The following options are available by right­clicking on the individual annotation:

Color Settings: Allows the user to change the
characteristics of the annotation

Rename: Allows the user to rename the user­defined annotation.

Move To Top: Moves the corresponding
annotation to the top of the Tree View within

11 | P a g e February 2011

the ‘User’ heading.

Move Up: Moves the corresponding annotation above the previous annotation within the
‘User’ heading.

Move Down: Moves the corresponding annotation below the successive annotation within
the ‘User’ heading.

Remove: Allows the user to remove the annotation from the Map View and Tree View.

Info: Provides the projected position of the annotation.

1.3.3 SeaClass Tree

The SeaClass layer contains three sub-layers as shown in the image below:

Manual Training - where training data points are stored
Neural Nets - for displaying the neural nets generated

from the training data
Classification - includes the results of the classification

process

Right-clicking on the Manual Training layer or any of its
sub-layers will give the following options:
