Color stereo airphotos taken at 2000 meters and a digital photogrametric work station were used to generate land surface, building base and heights and outlines for buildings. These were imported into TNTmips as 3D vector objects and a raster DEM was produced from them. The original orthophoto was then draped over the DEM in TNTmips' 3D simulation process. The results are quite impressive and well worth the download. This flight approaches and turns following the San Andreas Fault line.
Vegetation appears green, bare soil and rock shown in nearly natural gray, white, brown.
This fly over follows the surface of the irregular terrain of the Grand Canyon. Vegetation appears green, bare soil and rock in pink and magenta, most urban features in dark blue to purple, and water as black.
