WMTS TopPlusOpen

Presentation Service (WMTS) for a freely usable worldwide uniform web map based on free and official data sources. The product presents, among other things, free official geodata from the federal government and the open data countries Berlin, Brandenburg, Hamburg, North Rhine-Westphalia, Saxony and Thuringia. In addition, Mecklenburg-Western Pomerania and Rhineland-Palatinate provide their official spatial data for the TopPlusOpen as part of a cooperation agreement, so that these countries are presented exclusively by official data. In the other Länder and abroad, OSM data are mainly used in the corresponding zoom levels, which, from the BKG’s point of view, meet all quality requirements and can be combined almost seamlessly with official data.
