SonarTRX Pro (x64)

SonarTRX Pro (x64) has the ability to import sonar files from several sonar manufacturers and generate geo-referenced images from the sidescan data. It can extract depth-along-track as estimated by the sonar, at various time-intervals (1, 2, 5, ...) from the default sonar channel, for bathymetric processing. It can also calculate the "first echo return" based on the recorded sonar data, and allows for digitizing the seabed manually to define the depth used for slant range correction, should that be necessary.

SonarTRX Pro (x64) requires a 64 bit Windows operating system, which compared to a 32 bit system is capable of better utilizing available physical memory. This allows for loading larger sonar recordings and creation of larger MasterImages.

SonarTRX-PlusPack v2A

PlusPack v2A is an add-on product license that activates additional depth-export, track-line correction and export functionality within SonarTRX v20 and newer:

  • Import/Export of alternate data (corrected trackline, absolute elevations, transducer altitude...)
  • Export of a more detailed along-track depth-profile (XYZ data) for bathymetric processing of data from specific channel. The exported depth can be values estimated by the sonar itself, or values as calculated/digitized via SonarTRX. The exported data also includes time-stamps and water temperature, if available in sonar recording.
  • When used with SonarTRX v21 and newer, PlusPack v2A also enables option to Batch-export depth-along-track from multiple recordings. Depths are as estimated by sonar, from default sonar channel, and the export-interval is limited to a point every 2 seconds.

Please see the tutorials page for various PlusPack usage scenarios.

SonarTRX-PlusPack v2B

PlusPack v2B is an add-on product license that activates additional raster image-generation features within SonarTRX. The following additional image-tile types can be generated when PlusPack v2B is used with SonarTRX v23:

  • Raw images for each image-tile. The raw images contains one pixel-row per sounding, similar to a waterfall display without any speed correction. These images are saved to a separate output-folder, along with a CSV file containing image-attributes.
  • Rectangular speed corrected images for each image-tile, similar to a speed corrected waterfall display. The images has an along-track scale equivalent to the scale of the corresponding geo-referenced image-tile. This is the preferred image-tile format for down scan channels. The images are saved to a separate output-folder, along with a CSV file containing image-attributes.
  • Mosaic images with constant segment-heading, at location of each image-tile. These images are rendered to the appropriate side, but with no variation in heading. This is to expose features seen in the original data, but not necessarily visible in the geo-referenced images. If bottom-features are discovered during sharp turns, these images might be useful for further inspection and cross-checking with other images on a map. These images are referenced by the default KML output file and are saved in the same folder as the standard image-tiles.

Please see the tutorials page for various PlusPack usage scenarios.

Common functionality (all versions)

Data Import

The various SonarTRX file importers (for each type of sonar file) have several common features:

SonarTRX import dialog

View and edit data

SonarTRX has a built-in viewer / editor:

Cursor status and measure information and mini map

The cursor status information is shown below the view. Differential values are shown in brackets when carrying out a click & drag operation. The birds-eye map in the lower-left corner provides information about the location of cursor (small circle), targets (cross), selected target (circled cross) and active tile with respect to the trackline of the sonar recording (red line or circle). The location of the "page" (group of image tiles) currently loaded in the viewer is shown as the gray portion of the trackline. The above sample recording was obtained from available online xtf-samples. The sonar type was not specified.

The following is a summary of the sonar viewer / editor functionality that is common to all versions of SonarTRX:


Navigate within available data

Correction of data

Change view preferences

Measure, inspect and define targets and clips

Generating images

Having imported data and made any corrections using the viewer, SonarTRX can generate geo-referenced images for viewing with Google Earth or import to Geographic Information Systems (GIS). The SonarTRX Mosaic creation dialog includes many options to customize the output:
