Digital Elevation Models

Digital elevation models are derived from SAR (such as ERS, ASAR, JERS, Radarsat, Palsar) data using SAR interferometry. The product quality depends on terrain type and surface cover. For well suited terrain a height accuracy on the order of 10m is feasible.

The product is available in digital, as raster file, or in printed format.

DEM Example

Digital Elevation Model (DEM) generated with ERS-1/2 Tandem interferometry. Color scale and contour lines were used to indicate the terrain heights; the SAR backscattering is used as image brightness, UTM Zone 34, WGS-84, 20m pixel spacing. (ERS Data Copyright ESA, Processing by GAMMA)
