Having left this "News" section empty for a while, I thought I'd post something fun. I've purchased AgiSoft Photoscan to reconstruct 3D surfaces from photogrammetry. Here's my first attempt at reconstructing the top of a landslide that's active at Dorsey's Knob Park in Morgantown.
The 3D image is a bit incomplete, but what you're looking at is a series of fault scarps where each break in the asphalt marks a series of "fault cutoffs". Notice that you can see a yellow parking line in the middle block that was connected to the bock above. Also notice the series of poles (originally vertical and in a row) that have been transported and locally rotated due to the internal deformation of the slide. I hope to return and get the whole scarp when I've perfected the technique.

I plan to use this technique to reconstruct fracture geometries in 3D, similar to the LiDAR based technique including this excellent study: Wilson, C.E., Aydin, A., Karimi-Fard, M., Durlofsky, L.J., Sagy, A., Brodsky, E.E., Kreylos, O., Kellogg, L.H., 2011. From outcrop to flow simulation: Constructing discrete fracture models from a LIDAR survey. AAPG Bulletin 95, 1883–1905. doi:10.1306/03241108148
