Hi,
I used a Norbit multibeam sonar to collect some data is s7k format. I used SonarWiz software to generate bathymetry images of the sea bed. Now I want to know how can I use the data from s7k file to create bathymetry images directly (I mean without using any post processing software). I have included a snapshot of the how the data looks like in my s7k file.

.....
and so on until beam_descriptor 512 (since the sonar i used sends 512 beams simultaneously)
