Source cadastre — Sources in NRW (reference database) — WMS

This service represents all sources in the source cadastre of North Rhine-Westphalia, independently managed by five institutions, or their sampling points based on the country’s water stationing map (gsk3c). The attribute table provides information about the number, location and data holders of all objects displayed within a source area and shows the reference source. Sources from Geobasis NRW — i.e. from the state survey — are always reference sources. All objects captured in a radius of 10 m around the reference source are merged under a source NRW_ID. Overlapping radii are combined into a larger contiguous source area. If there is no reference source of Geobasis NRW in an area, the source closest to the area centre of gravity represents the reference source.
