Hi Matt, thanks for reading. When doing the comparisons, I exported the geometry from Terragen with the micro exporter, so it does include the added fractal detail. I don't think it would make a huge difference in the result, as I only added a small amount of fractal detail. My intent was to preserve the original geometry as much as possible while still introducing some unique features for the 3D photogrammetry algorithms to latch on to.
I actually presented some of this work to a large majority of the big names in the UAV industry at an NSF meeting yesterday. There was a lot of interest in our use of Terragen as a simulator for UAV mapping, so you may have some folks with questions headed your way.
