What's New in Triton Software

 

Triton software is continuously in development, upgrading current features as well as adding new functionality to meet
the changing needs of the survey community. Currently most of our software development is focused on adding new functionality to our Perspective data processing software, however we also are adding new sonar interfaces to our
Isis data acquisition software for multibeam, sidescan, and combined sidescan/subbottom systems.

Listed below are some of the new capabilities added to our software.

TRITON PERSPECTIVE

Software Version:  7.7.47.0

Release Date:  2015-08-24

 

Update AutoCAD Libraries

 

Added compatibility with the latest AutoCAD libraries for importing and exporting DXF files. Export format for DXF files is selected n the Program Settings and applies globally to all exports. Supported formats range from R14 through AutoCAD 2013. DXF files generated in Perspective are fully compatible with third party aplications such as Global Mapper for making final plots of the survey results.

New Target Utility

 

Developed completely new target utility that builds small mosaics of the target area from the raw data. Building mini mosaics improves image quality and increases position accuracy by using processed navigation to determine the location of each ping. This new utility uses the same Color and Histogram image enhancement tools used throughout Perspective. Measurements can be quickly made for determining the size of captured objects, with drop down classification options available.

 

New Target Utility

 

Russian Language Version

 

Translated Perspective software into Russian language and characters for use by Russian customers who prefer to work with software in their native language. Additional language packs will be coming soon!

Release Date:  2015-05-03

 

New Patch Test Utility

 

Built new patch test utility inside Perspective for quantifying GPS Latency, Roll, Pitch, and Yaw biases within the measure mounted angles and offsets for the acquisition system. Our new patch test supports both single and dual-head systems, as well as interferometric sonars. It works by looking for the minimum differences between 2 survey lines in the selected area using 'area' differences instead of just along a profile 'line'. Selecting a good area for each phase of the patch test is assisted by showing a DTM of each survey line on a separate map view.

Software Version:  7.6.301.0

Release Date:  2014-10-07

 

Water Column Data Viewer

 

Included water column data viewer in our Swath Editor for replaying XTF files with water column packets recorded. Continual playback options are available in addition to manually panning forward. Anomalies seen in the water column can be captured using our annotation tools to mark locations as well as the shape of the anomaly and sent to the map view for comparison with other data such as Charts, geoTiffs, or sidescan and subbottom data collected from the same location.

Software Version:  7.6.134.0

Release Date:  2014-02-06

 

Mosaic Combine Methods

 

Added ability to combine overlapping data using a root mean square (RMS) algorithm to improve results. Combining data to create a mosaic in Perspective occurs three times. The first option to select is how to combine overlapping survey lines, the second option sets the along-ping downsampling method to reduce the data density and increase processing speed, and the third option is for combining overlap pings within a single line. The image shown here includes examples using MAX, MIN and RMS for all three option, plus a fourth image using the mosaic defaults (RMS, MAX, RMS).

 

Mosaic Combine Methods

 

File Tree Layer Manager

 

This new capability allows users to perform two functions. For individual grid or mosaic files, this tool allows the user to remove multiple survey navigation lines from a grid or mosaic file. For managing layers in the file tree, the Manage Layers tool provides the user with the ability to re-order or remove multiple layers within a particular file tree node. Currently this capability has been added for Imagery file trees (DTM, CUBE, Sidescan) and for the Background/Geotiff file tree. The next release will include this capability for User Annotations, Features, and Vector file tree layers.

Software Version:  7.6.116.0

Release Date:  2014-01-06

 

Norbit WMBS Compatibility

 

High resolution Norbit WMBS multibeam data can be fully processed using Triton Perspective processing software. Processing includes DTM or CUBE gridded results with QC statistical grid layers. The example shown here was collected using Triton Isis MB-Logger by SeaHorse Geomatics. The WBMS-series are ultra compact multibeam sonars designed specifically for use on very small platforms. Norbitís wideband multibeam technology allows long range data collection, while simultaneously achieving very high range resolution.

Software Version:  7.6.088.0

Release Date:  2013-09-30

 

Reson S7K Snippet Processing

 

Significant changes were made to Geocoder for processing footprint time series "snippet" data from Reson S7K data files. If snippet data is present in the S7K files, it will be written into the GSF files for processing in Geocoder. By using the GSF files for processing the snippet data, soundings that have been flagged as 'bad' by the user during manual data cleaning will be excluded from the final snippet mosaic producing cleaner results than starting with the raw unprocessed data files.

 

Reson Snippets

 

Navigation Inserter

 

To support external processing of navigation and motion data as well as supporting "topless" AUV data acquisition systems, Triton has developed a tool in Perspective to allow the user to insert selected navigation and/or motion data from an ASCII text file into raw or duplicate XTF files. While it is possible to process navigation in Perspective, occasionally more advanced processing algorithms are needed. This is especially true for correcting navigation drift in AUV surveys performed without an LBL navigation system.

Software Version:  7.6.004.0

Release Date:  2013-06-18

 

New Release - Version 7.6

 

Significant changes were made to Perspective in the latest release, primarily related to sidescan processing. The biggest change was a redesign of the Mosaic Wizard, with new pages added to accomodate the new options and filters. Options for navigation processing have been made more intuitive and user friendly, both from the file tree and in the processing wizards. Click the image to the right for a detailed list of the changes made.

 

Improvements in v7.6

 

Bottom Tracking Improvements

 

Several new options were added to the bottom tracking module in Perspective including: auto-track from bathy nadir for combined MBSS sonars and interferometric sonars, works from the file tree for tracking all lines at once or from the bottom tracking dialog on a single line; across-track zoom for more precision with manual bottom track corrections; slant range correction in the bottom tracking dialog; and a position link between the sidescan waterfall window and the bottom tracking module.

 

Bottom Track Improvements

 

Mosaic Topo Corrections

 

Typical sidescan mosaics assume the seafloor is flat, and base the ground range from the sonar on the altitude of the towfish and the slant range (or time). When the seafloor is sloped or there is an object on the seafloor, the altitude below the towfish is no longer the same across the swath and errors in position are introduced. In this new release of Perspective, there is an option in the Mosaic Wizard to select an existing DTM in the project to use for correction the mosaic for changes in topography.

 

Mosaic Topo Correction

 

Moving Average Filter

 

For sidescan data that is grainy or contains noise, a moving average filter can help delineate objects or features seen in the imagery. On the Filters/Corrections page of the Mosaic Wizard, there is a new option to apply a moving average filter and to set the filter dimensions.

 

Moving Average Filter

 

Mosaic Range Clipping

 

New options have been added to Perspective's Mosaic Wizard for clipping the range of the sidescan record. Inner and outer boundaries can be clipped by meters (formerly only by %). A new option was added to set a maximum range from nadir for producing a cleaner mosaic from data that changes range during a survey line (such as Reson sidescan data). Also added ability to clip the sidescan record based on towfish altitude for compliance with NOAA 2012 Hydrographic Surveys Specifications and Deliverables.

 

Mosaic Clip

 

Snip/Constrain by Heading Change

 

A new constrain option was added for creating sidescan mosaics or bathymetry grids based on the amount of curvature in the survey line. This tool works in both the Bathy & Mosaic Wizards to constrain the extent of the grid or mosaic that is generated, and also in the Snip Line tool to allow users to snip the survey line based on curvature, or just to test the different parameters to determine what numbers to apply in the processing wizards.

Software Version:  7.5.505.0

Release Date:  2013-04-15

 

Navigation Line Profiles

 

Profiles can be extracted from bathymetry grid files along navigation lines. The extent of the navigation profile drawn will correspond to the extent of the navigation line displayed in the map view, allowing users to zoom into the data and pan along the line.

 

Nav Line Profiles

 

 

Export Mosaic to XYA

 

Sidescan mosaics can be exported to ASCII text files with amplitudes in dB. XYA mosaic exports are set to the same resolution as the original mosaic file and can be exported in any projection supported by Perspective.

Features for SeaClass Samples

 

New capability to auto-load sediment samples into SeaClass training sets. CSV files with sample information are loaded into Perspective into unique 'Feature Groups'. While creating the SeaClass training set, it is now possible to load samples from each feature group to use for the classification process.

Features for SeaClass

 

 

Export Navigation to CSV

 

For advanced navigation processing, Perspective allows the user to export navigation data from each raw data file to CSV formated files for external processing using MatLab or other scripting languages. This is very useful for recalculating AUV survey lines based on known start and end points. Once the navigation data has been reconstructed, it can be reloaded into the raw data files using our NAVinXTF utility. Also for viewing survey navigation lines in third-party GIS software, Perspective can export navigation lines as DXF polylines.

Software Version:  7.5.496.0

Release Date:  2013-03-26

 

GeoTiff Tiled Export

 

To increase the resolution of exported GeoTiff files, it is possible to tile the export into smaller higher resolution GeoTiffs. Tile sizes can be automatically set by choosing the number of tiles to create, or the tile size can be set manually to meet specific project requirements. This new tiling capability is implemented in the imagery exports from the bathymetry grids or sidescan mosaics, and also for the map composite exports for including background images, loaded vectors and feature files, drawn annotations, targets, etc.

Attitude Data Viewer/Editor

 

Motion data recorded to raw data files can be viewed with Perspective's new Attitude Editor. This is the first implementation of this tool with many features to be added for data editing. Currently its more a viewing utility than for editing, however there are some filters available in the Control Panel and some manual editing options for removing known bad points.

Software Version:  7.5.424.0

Release Date:  2012-11-20

 

Multiple Map Views

 

For simultaneous views of overlapping layers in Perspective, users can now open new map views of the same location. Each map view can be set to sync with the primary map display extent and scale. This is very useful for comparing bathymetry grids with corresponding QC layers, comparing repeat surveys, viewing the same object in overlapping sidescan lines having different shadow directions, and many other applications.

 

Multiple Map Views

 

 

Waterfall Annotations

 

For advanced navigation processing, Perspective allows the user to export navigation data from each raw data file to CSV formated files for external processing using MatLab or other scripting languages. This is very useful for recalculating AUV survey lines based on known start and end points. Once the navigation data has been reconstructed external to Perspective, it can be reloaded into the raw data files using our NAVinXTF utility. In addition to the ping location in XY and lat-lon coordinates, included in the CSV export is the sensor motion data and time of the ping. Also for viewing survey navigation lines in third-party GIS software, Perspective also can export navigation lines to DXF files.

Waterfall Annotations

Software Version:  7.5.381.0

Release Date:  2012-08-21

 

Snip Lines/Constrain to Polygon

 

Added ability to snip muliple lines in Perspective using a drawn annotation polygon or an imported DXF file. Dialog allows users to test output prior to snipping the selected raw data files. As an alternate to snipping the data files, the same polygons can be used during the mosaic or gridding process to clip the extent of the processed data.
