🌳 Object heights (nDSM) worldwide
Height of buildings, trees and other objects above the ground, precomputed as DSM1 minus DTM1 on a 1-metre grid — as Cloud-Optimized GeoTIFF in EPSG:25832, loadable tile by tile or as a merged extract. Currently in Germany 338,820 tiles, 394,843 km² (245.79 GB).
Same tiles as the DSM1, 1 km² each, 4 km² in MV/SN/ST; 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?
- Object heights — Float32 raster, 1 m resolution, metres above ground, open ground 0, at most 5 cm off the exact difference (LERC compression)
- On the DSM1 grid — roof edges and tree crowns stay sharp; where DTM and DSM are not aligned (Brandenburg, Mecklenburg-Western Pomerania, Saxony, Berlin), the terrain is resampled onto it
- Two flights per tile —
aktualitaetis the date of the surface model,dgm_aktualitaetandabstand_tageshow how far the terrain is from it; plusquelle_typ(laser/bild) andhoehe_max, the tallest object in the tile
An nDSM is only as good as its two sources: if several years lie between the DSM and DTM flights, objects built or felled in the meantime may appear wrong, and over water or at the state border, where there is no DTM, the nDSM is missing. Negative differences (measurement noise) are set to 0.
