Fly your own Black Ops or alien craft right out of AREA 51.
This model has been created combining actual satellite imaging and Digital Elevation Models (DEM).
So that the terrain you see here IS the terrain that is there.
The hi resolution image map has been painstakingly built from more than 130 images. And represents a square 110 miles on a side giving 1,110 Square miles with Area 51 at the center.
NOTE: The models and scenes were constructed in LW 8.5. The scene will work in in LW 7.0 and up, but you will need to adjust all surfaces to be double sided (as LW 7-7.5 see some of the polys as flipped, though they are not)
