The Specialized Information Service Cartography and Geodata (German: Fachinformationsdienst Kartographie und Geobasisdaten, abbr: FID Karten) belongs to the Berlin State Library (German: Staatsbibliothek zu Berlin Preußischer Kulturbesitz) which has a wide range of topographical maps in its holdings. These are referenced in the Topo-Liste.
The FID Cartography and Geodata supports researchers by providing global geodata. Links for researching geodata via global national geoportals are also included in the Topo-Liste. These web portals are mainly operated by official institutions and provide corresponding geodata or digital maps.
As a special service, the FID Cartography and Geodata also offers an overview of the options for accessing geodata on Africa.
