I've done all of it by hand with a little assistance from grasshopper. I started from this image:
(This was originally a PDF which I've flattened to upload). Essentially I extracted the contour lines, reassembled them (all 2,000+ were discontinuous, annoyingly) and then placed them at the correct elevation. Then I used a reasonably simple delaunay mesh triangulation component to break the contours into basically a point cloud and then triangulate a surface from it. I was worried this was going to be a really heavy process, but my computer did it in about 5 seconds. (32gb of ram). If there had been an easier way, I would have gladly done it. This took probably 60+ hours all told.
Next up is to do a lay up with some hardwood (not sure, maybe poplar) and mill the model on the 3 axis CNC.
By the way, here is a photo of the real site:
Here is the terrain as extracted from google earth
The google earth terrain is fairly accurate, but the resolution is only about 200'
Here is roughly the same shot of my new model, with 40' resolution
Not totally finished yet, but getting close.
The site is Yucca Mountain, Nevada
