3D building model LoD1-DE Hamburg

Description

3D building model LoD1-EN ATTENTION: This dataset will no longer be continued, the 2023 download is the most up-to-date and last. For the data set LoD1-DE up to and including 2022, fully automated flat roofs with a medium building height are formed from point clouds (airborne laser scanning or photogrammetry) and assigned to the buildings. Since 01.04.2023 the building model LoD1-DE is derived mathematically from the LoD2-DE building model. The LoD1 roof height is formed as an average of the standard roof shape LoD2. The building floor plan is basically taken from the official digital property map, so the model is compliant with the floor plan. The position accuracy corresponds to that of the underlying building floor plan. The height accuracy is approx. ± 5 m. Rough deviations are possible in individual cases with complex roof shapes. Shared geometry is managed redundantly. In addition, the buildings will be interspersed with site information from the Digital Terrain Model (DGM) held by the state. There is no manual post-processing of the individual models. The modeling complies with the AdV product and quality standard for 3D building models. The timeliness of the data basis is usually from the previous year, in the case of ALS point clouds sometimes also older. (Example: The download LoD2-DE 2023 is based on floor plans and point clouds from 2022). The LoD1-DE building model is available for the entire urban area of Hamburg (approximately 750 km2), including the island of Neuwerk. The data can be downloaded as a complete data set in the format CityGML V.1.0. Further data formats and excerpts can be obtained at 3d-info@gv.hamburg.de for a fee.
