Is there any technology that I can use to create a 3D underwater map of a lake/river? Ideally I need to be able to sail around the lake and the data needs to be stored so that when I have completed the navigation the appropriate software can translate the data in an electronic map showing depth, underwater structure, objects and other features hidden under the water.
Your forum seems to have the most related topics and you seem pretty swithced on.

You could use sonar I guess but consumer grade I have no idea
