Building heights from LoD2 and terrain from DGM1
Building heights and terrain are the basis for the massing model, section, shadows and sun hours.
Building heights
Berlin: LoD2 3D building models from Geoportal Berlin; where LoD2 is missing or implausible, the ALKIS height or storeys × 3.2 m (estimated). Cologne: LoD2 3D building model from Geobasis NRW. Stuttgart and Karlsruhe: LoD2 3D building models from the LGL.
The building outlines come from ALKIS. The massing model extrudes the outlines to the assigned height. The roof geometry of the LoD2 model is not used.
Terrain
DGM1 is averaged to 5 m. The sources are Geoportal Berlin, Geobasis NRW and the LGL. Missing areas are filled with Copernicus DEM GLO-30. Narrow structures such as bridges are filtered out.
Limitations
- Heights can be missing or estimated
- Terrain grids do not capture walls, steps and small landforms in full
- The exported terrain is relative to the centre of the site
