Hello!

I'm in a project where I'm supposed to make a bathymetric map of a flooded crater. I'm testing how to do it and I had a few problems.

A remote controlled boat collects the data by a GPS (location and depth). At my office, I take the SDCard from the boat and the file is a text format. The information on the file is like this:

 

 

$GPRMC,174859.000,A,4505.1729,N,06420.5123,W,1.75,28.53,080513,,,A*46
$SDDBT,6.6,f,2.0,M,1.1,F*04
 
I tried to use 2 programs to import the data - Undersee Explorer and ArcMap but none of them were able to recognize this format (.txt). I also tried GPSBabel to convert but it didn't work.
I need a file in sonar log (.slg or .sl2). I'm pretty sure that is not a hard issue, but I can't figure it out - I've never done this before.
 
Any suggestion will be welcome!
 
Thank you!!

Looks like a comma-separated file format - do you know what the columns mean - most importantly the coordinates and the depth? Maybe you could reformat this in e.g. Excel (or using something like python).

Looks like it's NMEA 0183 data, GPS Babel should be able to read that.

Thank you for reply! I'm trying to convert at GPS Babel as a NMEA data...
