Note:
CartoDEM is generated using Augmented Stereo Strip Triangulation (ASST) - indigenously developed software by Space Application Centre, ISRO. The seamless CartoDEM generation is an automatic process and makes use of limited Ground Control Points (GCPs) in long stereo strip pairs using dense feature matching, Triangulated Irregular Network (TIN) modeling and automatic long strip mosaicing. The generated DEM and ortho images of eachCartosat-1 segment are cut into tiles of 7.5x7.5 extents. The entire Indian region is covered by approximately 500 Cartosat-1segments with a total number of around 20,000 tile pairs.
