Using stereoscopic imagery (two satellite images taken of the same scene from different acquisiton angles) elevations may be computed to a degree of accuracy which rivals LIDAR (air-borne radar). Digital elevation models (DEM) serve the purpose of providing the user with a correction table when orthorectifying a satellite image and for constructing a 3D earth model.
For clients in need of an elevation map with a high degree of accuracy, satellite imagery provides many advantages over other methods, in terms of cost and ease of acquisition.

Water Shed Analysis

Stereoscopic satellite imagery allows computation of vector flow paths so that drainage patterns can be determined.
