3D Landscape (DSM/DTM) Service.

by Rohit Kumar
Our earth has a vast range of landscapes including mountains, valleys, densely forested or wooded landscapes and also man-made infrastructure. SATPALDA Geospatial Services provides 3D landscape services to our esteemed customers. 3D landscape include DSM (Digital Surface Model) & DTM (Digital Terrain Model) of 60cm, 1m, 2m, 3m, 4m, 5m and 10m resolution. At SATPALDA, we provide both relative DSM/DTM (no ground control) and absolute DSM/DTM (with ground control) as per the customers requirements. DSM reflects the top of the structures and vegetation and DTM represents bare earth which can be derived from a number of sources such as topographic maps, high-resolution stereo satellite imagery, medium resolution stereo pairs, radar satellite imagery and manned aircraft stereo imagery.

Topographic data is very critical for different scientific, technical and other applications. It is frequently utilized in preparing visualization tools such as perspective or stereoscopic views of the terrain. Topographic data includes all the basic aspects of land surface research including-
  • Archaeology
  • Base Mapping
  • Orthorectification
  • Civil Engineering
  • Topographic Mapping
  • Climate Impact Studies
  • Radio and Telecommunications
  • Watershed Modeling
  • Geological Exploration
  • Geomorphology and Landscape Analysis
  • Geophysics
  • Risk and Disaster Management
  • Intelligent Transportation Systems
  • Precision Farming and Forestry
  • Simulation & Training- Military, Aviation, Urban Planning
