I have sonar data collected in the format of an edge tech .JSF file, I have gotten the longitude, latitude, depth, and can get some more. I am having issues graphing the data as none of it is coming out the way it should. I am trying to use a contour plot to do it. If someone could help me out or give me a suggestion on what I should try or where I should go from here that would be great. I am programming in python
