A 3D mesh is a representation form of a 3D surface model generated from aerial image information. It represents the terrain surface including vegetation, buildings and other artificial objects (e.g. standing cars). For this purpose, adjacent three-dimensional points from the image correlation of the oriented aerial images are connected to a mesh. The mesh surface is then textured with the underlying aerial images. In recent years, 3D city models have been created in the municipal context, which are used as a planning basis for spatial analyses in three-dimensional space and for public relations work, among other things. The 3D mesh of Geobasis NRW is generated for the entire land area of NRW and represents a realistic model at the time of the survey. It serves as an efficient alternative to oblique aerial images and is suitable as a data basis for digital twins. Possibilities of use: Exploration for the continuation of the official basic map , Planning basis (e.g. for urban planning, monument preservation, environmental management), assistance for civil protection, economic development or tourism , visualization of computer-based analyses (e.g. for flood simulations, visual axes, shadow casting, noise propagation or wind currents), use in 3D navigation, real estate industry, public relations.","free_access_class":"FREE_NO_AUTH","auth_type":"NONE","homepage_url":null,"docs_url":null,"repo_url":"https://www.gis.nrw.de/geobasis/3D_mesh/SceneServer","status":"ACTIVE","verification_state":"VERIFIED","tags":["geospatial","housing","environment","construction"],"logo_url":"https://www.google.com/s2/favicons?sz=64&domain=gis.nrw.de","primary_source_url":"https://www.gis.nrw.de/geobasis/3D_mesh/SceneServer","extraction_confidence":"0.16","created_at":"2026-06-24T18:57:40.760Z","updated_at":"2026-10-12T20:48:49.623Z","last_verified_at":"2026-10-12T20:48:08.467Z","deprecated_at":null,"ranking_score":34,"last_ranked_at":"2026-10-11T12:17:34.553Z","last_seen_at":null,"last_validated_at":null,"last_uptime_at":null,"search_vector":"'2023':14B,249B,366B,601B
