3D mesh (SLPK)

Since 2023, a 3D mesh for NRW has also been produced from the aerial photographs. A 3D mesh is a representation form of a 3D surface model generated from aerial image information. It shows 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 emerged in the municipal context, which are used as a planning basis for spatial analyses in three-dimensional space and for public relations work. The 3D mesh of Geobasis NRW is generated for the entire state 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 base map, planning basis (e.g. in urban planning, monument preservation, environmental management), assistance for civil protection, economic development or tourism, visualization of computer-aided analyses (e.g. for flood simulations, visual axes, shadow throwing, noise spreading or wind currents), use in 3D navigation, real estate industry, public relations work
