Central Office for Geotopography

The Central Office for Geo-Topography (ZSGT) provides centrally digital cross-border spatial data of the Federal Republic of Germany to economy, science, administration and all citizens. The ZSGT is operated at the Service Centre of the Federal Government for spatial information and geodesy (DLZ) at the Federal Agency for Cartography and Geodesy (BKG) at the branch office Leipzig. The licensing of the spatial data is carried out on behalf of and on the basis of the conditions and product specifications of the Working Committee of the Surveying Authorities of the Laender of the Federal Republic of Germany (AdV).

Users profit from a comprehensive spectrum of Internet services that conveniently can be tied into custom applications and that continuously access the most current spatial base data. For this purpose, the DLZ operates highly available and high-performance web servers. Furthermore, the traditional provision of data in spatial and content selections, various georeferencings and data exchange formats is possible.

The data of the federal states (Laender) are merged and technically harmonized at the DLZ. Formal completeness and format consistency are also checked. Accompanying metadata and overviews of topicality provide the user transparently with information on the quality of the spatial data.

You can learn more about the free product portfolio of geospatial data of the federal states on the respective websites. Please find a list of all contacts on the website of the AdV.
