3D Urban and Terrain Modeling
The Digital Surface Model (DSMs) or DEMs are utilized in support of the pre-planning and lay-out of corridor surveys, aviation, telecommunication, area developments, engineering, construction activities, environmental and cadastre applications.
3D visualization models are essential for many applications, such as military operations, flight simulator development, disaster management, mapping of buildings, updating and keeping cadastral databases current, change detection and virtual reality.

If a 3D terrain visualization application requires good detail pertaining to the terrain features and terrain slopes for critical project decisions, an accurate digital terrain model and a digital surface model must be available to produce a satellite map.
