The service combines the background maps for the Heinsberg district. It represents the topographic maps of the state of NRW (DTK10, DTK25, DTK40, DTK100) and the district Heinsberg (German Basic Map and its successor the Official Base Map). In addition, current and historical aerial images from own and country flying are included. The map works are automatically displayed and hidden depending on the appropriate scale.
