From a building point to a 3D model
An address tells us where a building is located. However, for many planning and analysis tasks , that is not enough. After all , the exact location of the building and the area it actually occupies are much more important.
Let's take a look at energy and heating planning: Whether analyzing a neighborhood’s heating demand or planning a new heating system, the location of a building must be known as precisely as possible.
- Where is the building located on the property?
- How large is its footprint?
- How dense is the development?
- And which buildings are right next to each other?
Building coordinates provide a precise spatial reference point for a building. Building outlines also depict its actual floor area and shape. Together, they create a location-specific foundation on which further information—such as building type, use, households, or heating demand—can be spatially mapped and analyzed.
This is relevant not only for energy planning. The same principle applies to site analyses, infrastructure and grid planning, real estate appraisals, and building utilities: the more accurate the spatial data, the more precise the analysis.
In short: “Location-accurate” means not only knowing that a building exists at a certain address, but also knowing as precisely as possible where and in what form it actually stands.

Intelligent Placement: Nexiga house coordinates are intelligently placed within the official house boundaries and supplemented with additional house coordinates for approximately 28 million houses.
-
Corrective Placement: Nexiga building outlines are georeferenced polygons representing building floor plans and can be ideally combined with Nexiga building coordinates.
ZSHH = The “Central Office for Building Coordinates and Building Boundaries” consolidates official building data from the federal states and makes it available nationwide in a standardized manner with regard to data formats, fees, and licenses.
Nexiga House Coordinates
Precise Location of Buildings
Building coordinates map the locations of approximately 22.7 million buildings with addresses in Germany using X-Y coordinates and the corresponding mailing addresses.
Depending on the specific application, various levels of positional accuracy are available—ranging from official building coordinates to supplementary or interpolated coordinates.
Nexiga House Perimeters
Buildings as Exact Areas
Building outlines represent the floor plans of over 59.8 million buildings as polygons. They are derived from data in the real estate cadastre and provide a detailed representation of building shape, size, and development structure.
When combined with building coordinates, this creates a precise spatial data foundation for numerous analyses and planning efforts.
3D Building Models (LoD2)
The 3D building models depict buildings and structures throughout Germany at Level of Detail 2 (LoD2). The buildings are represented as simplified 3D shapes with flat roofs, based on their floor area and height.
The data is based on official information regarding the property boundaries, building height, and building use, as well as the correct mailing address. With up to 250 use categories —ranging from barns to single-family homes—building structures can be distinguished and analyzed in detail.
Building blocks
Approximately 3 million building blocks represent urban areas nationwide. They are generated using geoprocessing techniques based on data from the BKG (Federal Agency for Cartography and Geodesy) and serve as small-scale units of analysis for a wide range of applications.
