Digital Elevation Models


On demand and off-the-shelf Digital Elevation Models

Digital Elevation Models can be sorted in two general categories: Digital Terrain Models are (DTM) are digitized surface representations that model the “naked” earth, thus eliminating any man-made structures like buildings and bridges, but also natural surface features like trees and entire forests. Digital Surface Models (DSM), on the other hand, use pixels to represent actual surface patterns, which do include the shapes and heights of buildings as well as trees.

Digital Elevation Models have become essential for practically all planning applications, from flood prevention and flood analysis to the viewshed analysis for assessment of wind turbines or landfill sites; they are useful tools in determining the location of radio relay systems and cellular communication towers, for example. While publicly available data may be available for free, those are mostly too coarse, and tend to be unprocessed outdated. On the other hand, commercial products are verified, high resolution, and available on a regional or global basis with homogeneous quality. For the most up-to-date Elevation Models, data can be generated locally on demand. Sources are SAR and stereo satellite images or for most accurate models aerial reconnaissance using Lidar or photogrammetric solutions.
