Building geometry API

Fetch building geometry data from a building with the address as the input

Dataset

The building geometry dataset (3D BAG) is an up-to-date dataset containing 3D building models of the Netherlands. It contains 3D models at multiple levels of detail (LOD), which are generated by combining two open data sets: the building data from the BAG and the height data from the AHN.

There are data attributes describing a building: the number of floors and the area but also information about the surfaces of a building: surface type, area, perimeter, geometry. The goal of the Building geometry API is to expose this information to be able to fetch the geometry data of a single object.

Use case

• Use building geometry data in the addition to the Sustainability API for improved calculations

• Retrieve roof surface area's, its orientation and sloping

• Extract the orientation of the walls and its (shared) wallsurfaces

• Extract the object polygons in GeoJSON format
