🏙️ Surface models (DSM) worldwide

Unified surface model on a 1-metre grid: per tile the laser-based DSM, where unavailable the iDSM averaged to 1 m — as Cloud-Optimized GeoTIFF in EPSG:25832, loadable tile by tile or as a merged extract. Currently in Germany 338,942 tiles, 394,965 km² (1070.25 GB).

Tiles of 1 km² each; small areas can be merged into a single file on demand.

🇪🇺 Europe

Outside Germany we deliver nothing ourselves but link the open tiles directly at the source — the map shows the link list as soon as the rectangle lies over the country. Each country has its own page with source and licence; all countries at a glance under Europe.

What is included?

• Surface elevations — Float32 raster, 1 m grid, elevations in metres above sea level (NHN), including buildings and vegetation
• Source per tile — true laser DSM where available, otherwise an image-based surface model averaged to 1 m (BB, HH, SH and Bavaria's DOM20); the tile list carries quelle_typ (laser/bild), quelle_gsd (native resolution of the source) and original_laser_1m (true only for genuine, unmodified 1 m laser DSM)
• Currency per tile — survey or publication date according to the state, plus the survey period (befliegung_von/befliegung_bis) where the state provides it

Difference from the DTM1: the DTM shows the bare terrain surface, the DSM additionally buildings, trees and other structures.

Where does the data come from, how is it processed?

Each state supplies its surface model differently: most deliver a true laser-based DSM already on a 1-metre grid — that is copied unchanged on the server. A few states have no laser DSM (yet) or only a finer iDSM; such tiles are averaged to 1 m during merging with gdalwarp -r average (see dgm.tiles.meta.quelle_produkt and quelle_gsd per tile).
