WFS SN ALKIS NAS compliant

The property register is kept in electronic form in the Official Property Register Information System (ALKIS). The present Web Feature Service enables the targeted download of geo-objects in ALKIS based on a search query (direct access download service). The service provides the geo-objects at least to the extent of the nationwide uniform database according to the GeoInfoDok 6.0.1 (http://www.adv-online.de) in the format of the standard-based exchange interface (NAS). The service is designed for use in specialised GIS clients that can exploit geo-objects with complex geometries according to GML 3.2.1 and AdV-URNs (for units of measurement, coordinate reference systems and object references) and have functionalities for processing complex NAS structures.
