How-to-FMGT - Caris HDCS Import as Bathymetry source

FMGT has the ability to work with many different types of data, one of them being the HDCS format from Caris. 

This how-to brings you step-by-step through the process of how to properly bring Caris data into FMGT. 

 Step-by-step How-to: 

Step 1: Ensure Licensing is set up correctly:

FMGT must be able to find your Caris license in order for your HDCS data to be brought in, or you will receive a Caris licencing error when trying to bring in your HDCS data. If you use a dongle, ensure it is connected and that all dongle drivers are up to date. 

If you use a license file, follow the steps outlined below.   

In FMGT, open the Preferences window from the File dropdown menu:

In the shared preferences tab, set the Caris licence path to your license file. 

Please note: FMGT looks for either a .dat or a .sit licence file in this path.

If FMGT doesn't recognize your license file, please rename a copy of it to correct the suffix.

Step 2: Import files: 

To import your data, access the 'Add Source/Paired Files' from the File drop down menu: 

A window will appear, asking you to specify the type of backscatter data you would like to pair with your HDCS data. 

Once you have selected your backscatter files, FMGT will then ask you to specify which bathymetric files you would like to bring in. This is where you will select your HDCS files. 

You will then be prompted to specify which files to pair, the merge options, and timing options:


The files to be paired must have the same name to be paired automatically. For example, in the image above the folder that the bathy file is in has the same name as the .7K Snippet file, so FMGT was able to match them automatically.

The pairs can be set manually as well.

Next FMGT will ask for the coordinate system of the imported data. Once that is set, select finish. 

FMGT will now merge each pair of files into a single merged.gsf file to work with.
