DEM

Summary

Digital Elevation Model (DEM), is the digitized simulation of terrain through limited topographic elevation data (i.e. the digitized representation of terrain surface). It represents the ground elevation with a set of ordered numerical array. It is a branch of the digital terrain model, which can be used to generate all other terrain feature values.

Usage

Before you can generate a digital elevation model, first Classify Ground Points. Click on the Terrain > DEM.

Based on DEM, a myriad of products including Slope, Aspect, Roughness and Contour can be generated.

Note: Point clouds that are used to generate DEM need contain ground points.
