Dienstleistungszentrum BKG-Homepage


With the product TopPlus-Web-Open, the BKG breaks new grounds and creates for the first time a consistent web map, completely based on free or open data sources. For this purpose, the BKG merged, processed and combined many different data sources in order to achieve the best possible map presentation.

The web map TopPlus-Web-Open has 18 predefined 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)
At present, no further maps are available in the service beyond the mentioned display areas.
