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 side scan sonar, shallow seismic, single beam 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 export single beam (sub bottom) data as XTF. The following XTF records are supported when writing XTF files:
The XTF export tool can only be started from the "Raw Data File Manager" in Hydromagic Survey. This option is not available in Hydromagic Dredging, since no raw data files are used in this application. First open the "Raw Data File Manager" by right-clicking the "Raw Data" folder in the "Project Explorer". From the pop up menu which appears, select the "Manage Files..." option.
Right click the "Raw Data" folder and select "Manage Files...".
In the "Raw Data File Manager", multiple export options are offered, including HYPACK, SEG-Y and XTF format. Using the exporting tools, you can export one or more files. Select the raw data files you want to export and click the "Export XTF" button to start the XTF export tool.
The raw data files manager shows a list of raw data files in the project.
Click the "Browse..." button to select in which folder the XTF files will be written. By default the "Exports" folder in your project map will be used, unless you selected another folder in the past. When one or more files already exist you will be notified. To force replacement of existing files, check the "Overwrite existing files without warning" check box.
When you didn't select any file from the "Raw Data File Manager" tool before opening the XTF export tool, you can select the files to export by clicking the "Select..." button. From the windows that opens, you can select the files to be exported by setting the checkboxes.
Select which raw data files will be included in the export.
Check the channels you want to include in the export. You can choose the regular echo sounder channels (low and high frequency) as well as sub bottom data channels. When the echo envelope samples are available they will be stored in the generated XTF files as well. You can click the "OK" button to start the export process. When the export did not complete successfully, you can refer to the "Processing" tab of the activity view for more details on the error shown.
Select which channel(s) to export, and click OK to start the export process.
