digital elevation models
with 5 m or 10 m post spacing

Euro-Maps 3D DSM is a homogeneous, 5 m spaced digital surface model product including detailed flanking information consisting of several pixel-based quality and traceability layers.

The Euro-Maps 3D Basic DEM for Ortho product consists of a 10 m digital elevation model and a 2.5 m ortho layer in the same geometry. Buildings were automatically removed from the DSM, whereas the heights of most forest areas are present in the product. Major water bodies were detected based on Sentinel-2 data and flattened. In urban areas, it is a very good approximation to a digital terrain model (DTM). This dataset is a perfect x, y and z reference for the orthorectification of HR and VHR images.

Ortho layer, for visualisation here with 5 m instead of 2.5 m resolution to match the 5 m post spacing of the DSM. Click to enlarge. DSM, hill-shaded. Click to enlarge. Number layer: red to lime = 0 to 12 = number of Cartosat-1 stereo pairs used for the generation of the height value. Click to enlarge. Source layer: green = derived from Cartosat-1 stereo data, red = filled with another DEM, yellow = edited manually and derived from surrounding values, blue = detected as water body and edited accordingly. Click to enlarge. Quality layer: green = meets or exceeds the quality described in the product specification, red = may not meet the quality described in the product specification. Click to enlarge. Accuracy vertical layer: green = 5 m for slopes < 20%, yellow = 7 m for slopes 20% - 40%, purple = 10 m for slopes > 40%. Click to enlarge. Subset of Euro-Maps 3D. Click to enlarge
