Digital Surface Models

  • DSMs representing ground and above-ground features including vegetation and man-made features
  • Derived from WorldView-1, WorldView-2, and GeoEye-1 stereo imagery
  • Created using state-of-the-art ATE algorithms
  • Best results over areas of low vegetation and built-up areas without highrise buildings
  • Web-based delivery
