Which is higher SRTM DSM or DTM dataset?
For the associated built up areas the SRTM DSM dataset is in average about 2.5 meters higher than the official DTM for the Cologne Region and the Ruhr Basin. Depending on the relief the overestimation is higher for the Rhineland Slate Mountains. The computed mean value for the associated forested areas was very different.
How is a Digital Elevation Model ( DEM ) derived?
Digital Elevation Model (DEM) is a digital cartographic dataset in three ( XYZ) coordinates and has been derived from contour lines or photogrammetric methods.
What is a Dem, DSM or DEM in opendem?
If you want know what a DEM, DSM or DEM is, please visit the Definitions Section. First the processing of an enhanced SRTM Digital Surface Model (DSM) is explained. This step is also necessary for the following processing of a Digital Terrain Model (DTM) on the basis of OpenStreetMap vector data.
How is SRTM Digital Terrain Model ( DTM ) processed?
SRTM Digital Terrain Model (DTM) Processing The SRTM mission mapped the structure of the earth´s surface including builtings and vegetation. OpenStreetMap data was used to correct the height values for forested and built up areas. The resulting DTM is only an approximation, depending on many factors: 1.
