WFS NW ALKIS Owner Data Simplified Schema

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 only provides the following geo-objects limited to the essential properties in the format of a simplified data exchange scheme defined in the “AdV product specification ALKIS-WFS and output formats (Shape, CSV)” (see www.adv-online.de): Land plots [including owners], buildings, actual uses, administrative units, cadastral districts. The service is designed for use in simple, practical GIS clients without complex functionalities. Output formats are Shape and XML. If multiple attributes are present (e.g. actual uses or addresses), these are listed by defined separators separately in the corresponding attribute. The service includes personal data and is secured (in the LVN NRW), registration is required for access. Status of the data used: 01.01.2023.
