REST API NW 3D Mesh (I3S)REST API NRW 3D Mesh (I3S)
REST API providing access to a 3D mesh dataset for North Rhine-Westphalia, produced since 2023 from aerial imagery by Geobasis NRW. The mesh is a textured 3D surface model derived from image correlation of oriented aerial photographs, representing terrain, vegetation, buildings, and other objects as they appeared at the time of survey. Covering the entire land area of NRW, it offers a realistic alternative to oblique aerial imagery and serves as a data basis for digital twins. Applications include urban and spatial planning, monument preservation, environmental management, civil protection support, flood and noise-propagation simulations, shadow casting, 3D navigation, real estate, and public relations.provided in the I3S format for streaming 3D scene layers.Since 2023, an additional 3D mesh for NRW has been produced from the aerial images. 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.

Data access
This API doesn't publish a machine-readable schema (such as an OpenAPI spec) that we can read automatically, so there's no field list to show here. See the documentation for its available endpoints and response formats.
