Sample MPEG video presentations made with TNTmips Description NASA space shuttle image draped on a USGS Digital Elevation Model. This fly over displays the active 3D north arrow feature added to 6.1 of the TNT products simulator. The north arrow adjusts direction according to flight direction. At the bottom of the first two you can see the plan and profile view of your path. Vegetation appears green, bare soil and rock in nearly natural gray, white, brown and magenta.
Ice is visible as cyan on lakes of black.
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.
