WFS NW ALKIS Floor Plan Data AAA Model Based

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 in a format defined on the basis of the norm-based exchange interface (NAS) in accordance with the GeoInfoDok 6.0.1 (http://www.adv-online.de) at least to the extent of the nationwide standard database. The encoding is adapted to the user by using geometries according to the OGC-Simple feature standard (http://www.opengeospatial.org/standards/sfa), units of measurement based on UCUM (http://unitsofmeasure.org/), OGC-URIs for EPSG coordinate reference systems, HTTP-URIs for reference of objects (http://www.w3.org/Protocols/Specs.html) and additional inverse relations. In this case, WFS-getFeature requests are usually used with a query that selects the referenced object, unless otherwise stable URIs are offered for the objects. The service is designed for use in practical GIS clients that can exploit the customised geo-objects as well as have functionalities for processing complex NAS structures.
