The Federal Agency for Cartography and Geodesy (, BKG) is Germany's national mapping agency. It is located in Frankfurt, with a branch in Leipzig. It operates the Geodetic Observatory Wettzell.
In July 2024, Germany summoned the Chinese ambassador over a 2021 cyber-attack against the Federal Agency for Cartography and Geodesy attributed to "Chinese state actors" for the "purpose of espionage."
The BKG has the following specific responsibilities:
In addition to its specialist work, the BKG contributes to coordinating geodesy and geoinformation within the German federal system. These include the Central Agency for Geotopography (ZSGT) and the Coordination Office of the German Geodata Infrastructure (GDI-DE). By coordinating the GDI-DE, the BKG also serves as the liaison office with the European Commission within the framework of the EU INSPIRE Directive, which requires all member states to provide public geoinformation online according to uniform professional and technical rules.
Until 2012, there was no legal basis at the federal level to establish terms of use for the provision of geodata and geodata services. Since the last amendment to the Geodata Access Act (GeoZG) came into force on November 16, 2012, federal geodata and geodata services have generally been available free of charge for commercial and non-commercial use.
Due to the technical proximity, the office of the Permanent Committee on Geographical Names and the administrative headquarters of the International Earth Rotation and Reference Systems Service are also located in the BKG.
