This publication of geoinformation provides download links for GetCapabilities documents via WMS. The platform also runs a WFS service as can been seen here.

I wonder if it is possbile to compose a download link for ShapeFiles/GML or another format which can be converted ... from the given WMS information. I managed to display the street tree information in QGIS and could load details for individual features. However, this is pixel data and I would like to download vector data if possible.

The second GetCapabilities document defines layers named pflanzstandorte2011 and pflanzstandorte_aktuell. It would be nice if these were accessible via the platform's WFS API.

FYI not all WMS implicitly deploy WFS. Having said this, there are a couple of approaches to help:

1./ scan the Capabilities XML for (optional) Layer/DataURL elements. If they exist, DataURL/@xlink:href should point to a download of the data

2./ Use the WMS DescribeLayer operation to examine whether there are associated WFS or WCS endpoints (ref: http://docs.geoserver.org/stable/en/user/services/wms/reference.html#operations) to the given layer

  • Which of the two Capabilities XML should I scan? Can you tell what the DescribeLayer URL is for this server? This and this are not valid. – JJD Jan 27 '14 at 13:06

    Looks like this WMS does not support the DesribeLayer operation, then, nor has any Layer/DataURL. The two approaches above are supported by the WMS specification, however appears not to be implemented by the service provider, in this particular case. – tomkralidis Jan 28 '14 at 11:46
