WFS ammonia background concentration

Ammonia background concentration is needed for a. the assessment of the degradation of ecosystems in Baden-Württemberg with the help of critical levels and b. for the design of ammonia pollution zones. Please note the following information on the completeness and quality of the data provided: due to inaccuracies in the acquisition of subject objects, non-valid geometries according to OGC schema validation occur occasionally. As GIS servers such as ArcGIS servers, GeoServers or UMN MapServer need to use/process more and more accurate data bases, the test routine is always further developed and encourages inaccuracies (e.g. by third-party software) in the tolerance range as well as in topological detection. This means that geometries can no longer be represented or captured. The contested geometry errors include, among other things, self-intersections (self-intersections) or double support points. The LUBW therefore cannot guarantee the completeness and stability of the Download Service (WFS). Therefore, if necessary, please check the completeness based on the presentation services (WMS) also offered.
