TopPlusOpen - The open maptypeProduct Information

Date 2018.06.08

With TopPlusOpen, the Federal Agency for Cartography and Geodesy breaks new grounds and creates for the first time a consistent web map, completely based on free and official data sources.

For this purpose, the BKG merged, processed and combined many different data sources in order to achieve the best possible map presentation. Among others, free official spatial data of the Federal Government and the Open Data states Berlin, Hamburg, North Rhine-Westphalia and Thuringia are presented in the product. Furthermore, Brandenburg, Mecklenburg-Western Pomerania and Rhineland-Palatinate provide their official spatial data for TopPlusOpen based on a cooperation agreement so that also these states are presented exclusively by official data.

The web map TopPlusOpen has 18 levels of detail - from the worldwide overview map to the detailed city map in Germany. As standard, the product is available in the widespread Web Mercator Projection (EPSG:3857). Via the WMS interface, the web map may also be called in further common projections. The web map is divided into three different display areas:

  • World (small scale)
  • Europe (medium scale)
  • Germany and neighbouring countries (large scale)

Additionally, the TopPlusOpen contains high-resolution Presentation graphics. Thus for the first time free and graphically uniform map data are available with full coverage for the territory of the Federal Republic of Germany and the adjacent areas of neighbouring countries in the scales 1 : 5,000, 1 : 10,000, 1 : 17,500 1 : 25,000 and 1 : 50,000, that are optimally suited for printing.
