Digital Surface Model with generalized textures, generated automatically without editing using WiMap DSM. This DSM was generated from two Z/I DMC vertical aerial images, 0.25 m resolution, 2500 m flying height. See more examples here.
WiMap® DSM creates Digital Surface Models (DSM:s), ortho photos and 3D virtual models from stereo images, either aerial images or Very High Resolution (VHR) satellite scenes like WorldView, GeoEye, QuickBird and Ikonos. WiMap DSM uses the full bit depth and number of bands of the input images. ReVisitor can produce DSM:s and ortho photos for you at your request or you may license the WiMap DSM software.The DSM:s capture sharp changes well, e.g. vertical walls, and the overall quality is high with few mismatches.
DSM:s may be exported as raster or as TIN. For raster based DSM:s, the export format is either 16-bit integer or 32-bit floating point GeoTIFF:s. For TIN export, the ISO ratified X3D format is used.

Digital Surface Models with generalized textures, generated automatically without editing using WiMap DSM. This DSM was generated from a demo set provided by the National Land Survey, Sweden. The demo set contains two Z/I DMC vertical aerial images, 0.50 m resolution, 5000 m flying height.
