WebThe terrain dataset is then generated within this feature dataset and can encompass much more than just the lidar data. Terrain datasets will help you with the following: Represent and model the terrain of study areas by integrating 3D-based mass point observations with other data sources such as 3D features captured using stereophotogrammetry. WebDigital Terrain Elevation Data (DTED) DTED is a uniform matrix of terrain elevation values. It provides basic quantitative data for all military systems that require terrain elevation, slope and gross surface roughness information. Data density depends on the level produced. DTED0 post spacing is 30 arc seconds (approximately 1000 meters).
