The official House Coordinates of Germany (HK-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 HK-DE of the Surveying Administrations of the Laender based on standardized fee and license models. The ZSHH currently provides an updated HK-DE database twice a year. 

• HK-DEs document your individual added value, for example in the following areas:

• Integration in web services for mapping and navigation services on mobile devices,
• Improvement of the bearing district administration and complaints processing for publishers,
• Integration in network documentation and information as well as sales and marketing for utilities and companies from the telecommunications sector.
