Deriving a digital surface model

A high resolution digital surface model (DSM) can be derived from the edited high density point cloud. The DSM will represent the height, above mean sea level, of the features in your image (e.g. crops, buildings, trees, etc.). The DSM can further be processed to derive crop canopy height and 3D models of the mission area. Figure 5.12 is an example of a DSM generated for a UAV mission area in Bangladesh
