Height Detection From Top Down?

Hi Guys,

I have a client that is looking to detect the height of a mound of material (dirt, gravel, rocks, etc.). I have yet to find a sonic sensor that can do this accurately at a 25m mounting height.

Normally, we set a camera up at some set distance away to view from the side, but is there a way to look top-down and determine the height? The issue becomes that we would have to erect a tower and run power and data (or use wireless) if we go with the first option.

Thanks very much!
