What is the XTF Format ?

In 2009, ECA GROUP acquired Triton Imaging, Inc., which is a world-renowned specialist in sonar post-processing and underwater imaging software.

Developed by Triton Imaging, Inc, the XTF format stands for eXtended Triton Format. It is an open source format used for recording hydrographic data.

The XTF file format is now widely used to store data produced by many different types of sidescan sonars, single beam and multi beam echo sounders and navigation systems. The format is regularly evolving with new needs.

As the XTF community leader, ECA GROUP makes the link to the manufacturers’ record types and data formats specificities, will maintain the XTF format for the years to come and has decided to publish its description on its website for all to download.

This document is intended to address file format and suggested ways to process XTF files.
