Terrain
The Terrain module contains a range of products required for terrain production, such as DEM, DSM, contour line and cross section, etc. of which the Digital Elevation Mode indicates that the bare earth surface (vegetation and other objects are removed), the Digital Surface Model represents the surface characteristics of terrain and other objects (e.g. tree canopy), and Canopy Height Model indicates the normalized height of vegetation and ground objects. Hillshade maps can be created by any digital model for visualization.
