On the one hand, the municipal boundaries of the association (for the city of Krefeld as well as the districts of Kleve, Viersen and Wesel and their affiliated municipalities) on the other hand, the regional service for ALKIS floor plan data in a simplified scheme (for the city of Bottrop as well as the district of Mettmann and its affiliated municipalities). Since the underlying data has a very high level of detail, and the point amount is too high for many other applications, the data is generalized (simplified) via a Douglas-Peucker filter with a tolerance of 20m and then output as an OGC WKT string in text files.
