Triton eXtended Format files

eXtended Triton Format (XTF) is a file format developed by Triton Imaging, Inc for recording hydrographic survey data.
XTF is the most commonly used format for this type of information in the hydrographic survey industry.

XTF supports sources including sidescan sonar, shallow seismic, singlebeam and multibeam bathymetry,
as well as associated position, time and altitude information.

An XTF file consists out multiple data structures placed sequentially in the file.
This way the file format can easily be extended with new functionality.

At this moment Hydromagic can read and convert the following data structures from an XTF file:


Select file format

The first page of the wizard allows you to set the format of the file(s) we wish to import.
Since this tutorial is about importing XTF data, we select the 'Triton eXtended Format Files (*.xtf)' option from the drop-down list.

Select file format


Select file(s) to import

In the second page of the wizard you can select which files to import.
Click the 'Browse...' button to select the folder on your computer where the files are stored.

After changing the folder the file list is reloaded, and you can use the check boxes to select one or more file(s) to import.

Import options

When the vessel's X and Y positions in the XTF file are projected coordinates rather then WGS84 geographic coordinates,
this page allows you to set the coordinate reference system used in the XTF file.

Starting the import

When the format, the files and the additional options has been set, you can start the import process by clicking the 'Finish' button on the last page of the wizard.

The file currently processed is displayed in the statusbar at the bottom of the screen and the wizard shows a message box stating 'File(s) successfully imported as raw data file(s)' as soon as the process has completed. Click 'OK' to close the dialog and the imported files will be centered in the map view (only when they contain position data).

Checking the imported raw data file(s)

When the import has completed, you can right-click the generated raw data files, and select 'Analyze Data...' to inspect the imported values and timestamps.
