It sure is. The key I found to it was that you'll need to zig zag over structure a couple of times and then you'll have the most detailed maps.

I uploaded another recording from Kempenfeldt Bay and I had drove over the structure several times while recording. When the map was produced the detail of contour lines was amazing. That was on the free program so it had 5 foot contour lines. With some of the paid subscriptions you can get 1 foot detail!
