In remote regions around the world, where little or no source data is available, the elevation models can be produced from stereo satellite imagery utilizing automatic DSM extraction or photogrammetric techniques (depending on the applications), from satellite sensors.Ģm Digital Surface Model (DSM) produced from Pleiades-1 Stereo Satellite Imagery There is a variety of DEM source data available at various resolutions for developed areas and the suitability of this available DSM's/DEM's or DTM's data is depending on the project objectives and specifications. The tri-stereo acquisition reveal elevation that would otherwise remain hidden in steep terrain or urban canyons in dense built-up areas. and the latest satellite sensor Pleiades Neo can be programmed to collect tri-stereo imagery for the production of high quality 1m-2m DEMs for 3D urban and terrain modeling.

Satellite Imaging Corporation (SIC) provides orthorectified mono and stereo satellite imagery that can be processed for visual of terrain conditions in 2D and 3D production of digital elevation models (DEM) from various stereo satellite sensors including the WorldView-4, WorldView-3, WordlView-2, and the latest Pleiades Neo satellite sensors at 30cm resolution that can support project planners, emergency operation managers, and logistics managers to plan field operations in a computer environment ensuring that the best terrain conditions and access is provided to achieve project objectives.
