3D city model LoD1-DE Hamburg

The 3D city model of Hamburg is available in two variants, which differ in terms of their level of detail: LoD1-DE and LoD2-EN Areas of application of the data of the 3D city model are urban and spatial planning, architecture and real estate marketing.However, the data of the 3D city model are also suitable as a spatial reference and basic information for the construction of geoinformation systems and for linking with or as background information for spatial subject-specific data for specialist information systems, for computational intersection and analysis with thematic information as well as for spatial planning of all kinds. All tasks for which a spatial reference is required or helpful are also part of the application areas of the 3D city model. These include, among others: » Energy, forestry and agriculture » Administration » Demography » Housing » Land use planning » Regional and route planning » Road construction and roads @-@ management » Facility Management » Traffic navigation and fleet management » Transport » Water science and water management » Ecology » Environmental protection » Geology and Geodesy » Culture, recreation and leisure » Communication Data quality (LoD1-EN): The model in the LoD1 (Level of Detail 1) depicts the buildings in simplified form as blocks. The building heights were calculated by averaging all existing laser data of the building roof surfaces. It is set up for the entire urban area (about 750 km²) and contains about 360,000 buildings. The buildings of the LoD1-DE are also mixed with terrain information of the digital terrain model (DGM) held at the state operation. The data can be submitted in most common 3D data formats. The building floor plan is basically taken from the official digital property map. The building is presented as “blocks”. All buildings are depicted with a flat roof. The location accuracy corresponds to that of the underlying building floor plan. The height accuracy is mostly ± 5 m. Coarse deviations are possible in individual cases with complex roof shapes. Shared geometry is managed redundantly. )* )* Source: ADV “Product Standard for 3D Building Models”
