3D building model LoD3.0-HH Hamburg untextured

The 3D building model LoD3.0-HH is based on a manual evaluation of the roof landscape. All buildings and structures in Hamburg (except the islands of Neuwerk and Scharhörn) were analysed photogrammetrically and modelled in three dimensions. Not only the buildings from the official cadastral register were used, but all buildings that existed in Hamburg at the time of data collection. The data basis for the evaluation is a nadir and oblique image flight from 2020. A detailed roof landscape was modelled that goes beyond the usual LoD2 classification. Significant roof overhangs were usually recorded as well as roof structures over a size of one square meter. The building models are placed on a digital terrain model, which was calculated with a resolution of five meters taking into account fracture edges. (DGM 5H) The building IDs are essentially identical to the cadastral register (ALKIS), but in individual cases there may be deviations in both the floor plan and different IDs. The building data is available for all five areas: Area 1 with about 34,000 building models mainly from the inner city area, Area 3 in the area of Harburg and Hamburg's southwest (about 80,000 objects), Area 5 with Hamburg's northeast (mainly Wandsbek, about 177,000 objects), Area 2 (Bergedorf, about 80,000 objects) and Area 4 with Altona and Hamburg's west (about 160,000 objects). This dataset is based on the 3D building model LoD3.0-HH. The geometries are identical, the textures are missing.
