The official Building Polygons of Germany (HU-DE)

The "Central Office House Coordinates and Building Polygons" (ZSHH), set up at the Agency for Digitisation, High-Speed Internet and Surveying in Bavaria, merges and provides the HU-DE of the Surveying Administrations of the Laender with standardized fee and license models. ZSHH currently provides an updated HU-DE database once a year.

• The HU-DE document their individual added value e. g. in the following areas:
• Visual appreciation of road maps for internal company use, in Internet services or mobile applications
• Data basis for 3D city models
• Detached house representation, especially for large map scales, alternatively also in combination with the official House Coordinates
• Reference data for professional geographic information systems - e.g. for calculating the floor area of buildings or sealed surfaces

Customers include companies from the navigation sector, the telecommunications and geo marketing segment as well as utilities, network operators and companies in the real estate sector and, in addition, a wide variety of users from public administration, science, research and education.

• Contents of the HU-DE:
• The polygons of the Shape files do not contain any design geometries, roofs, or underground buildings.
• The HU objects have three mandatory attributes:
  • "AGS" (Amtlicher Gemeindeschlüssel – official Municipality Key)
  • „OI“ (Objektidentifikator – objectidentifier)
  • „GFK“ (Gebäudefunktionskennung – building function).
• Information about building age or its owner are not included.
• The coordinates are issued by default in the spatial reference system ETRS89 / UTM.
