A SPOT DEM is a digital elevation model produced by automatic correlation of stereopairs acquired by the High Resolution Stereoscopy (HRS) instrument on SPOT 5. Unlike a digital terrain model (DTM), which describes the distribution of terrain or "bare earth" heights, a DEM includes "first surface" elevations with vegetation and man-made structures. A SPOT DEM has a post spacing of one arc second or 20 meters.
With more than 100 million square kilometers already covered across 2/3 of the globe's land surfaces, SPOT DEM is the ideal solution to ensure rigorous registration of all your data.
SPOT DEMs significantly improve registration of data layers in digital mapping. They also are therefore widely used in geographic information systems (GIS) for land management and terrain modelling. Applications include: impact studies, rail and road infrastructure studies, mobile telecommunications engineering, structural geology surveys, oil exploration, erosion studies, mapping, flight simulation. A SPOTView Ortho can be draped over a SPOT DEM for a more realistic 3D view of terrain, which helps multidisciplinary teams to work more closely together.Why SPOT?
- Easy to use cartographic or geographic projection
- Priced per square km. and framed to match your exact region of interest
- Quick turnaround of 2 weeks for areas < 20,000 square km.
