Good evening SB,
---
The Short - Looking for knowledgeable people to help me learn/set up a sonar system to create 3d bathymetric maps.
The Long -
One of my pet projects for years has been mapping dive sites wherever i work, just very general lap and long and potions etc.
Now i am in a position where i have access to vessels, the knowledge of NMEA systems and lots of space to explore for diving...
A lot of modern depth sounders and chartplotter produce amazing picture clarity, im looking for a way to either save the side scan tracks from a charplotter so i can stitch together, or more ideally, save the depth, position co-ordinates from a depth sounder and import into a program to create a bathymetric map (i used Surfer back in Uni). I know some garmins and humingbirds have an option to create your own maps. Is this just a outline or using the side scan sonar images i cant seem to find out.
In a perfect world i would love a small towed array that can save the data for processing later on a land based machine. Tritech offered a good system at one point for about $4000 USD but that was a few years ago and tech has moved on so quick that an off the shelf garmin chartplotter with CHIRP transducer seems just as good resolution! Otherwise i can T hardware into the NMEA backbone if a vessel already has the right transducer.
Ive seen what seem to be some great programs like ReefMaster, if anyone has any experience?
Pretty much all of the work i would do would be less than 100 foot and a majority at less than 60.
There seems to be so much out there to use im getting my self confused, if some one can straighten me out a bit it would be greatly appreciated!
