qgis – Downloading WFS Data Using QGIS

qgisqgis-3wfs

I tried to download data from WFS server but it doesn´t work with Qgis 3.2.2.
I connected to https://www.wfs.nrw.de/geobasis/wfs_nw_alkis_vereinfacht Then I connect to server and wanted to preselect a specific area by

  1. Query e.g. select * from flurstueck where city= 'köln',
    or:
  2. by tagging the "only request features overlapping with the view extent".

But both doesn´t work for me.

Failure message:

Layer ave:Flurstueck : Download of features for layer ave:Flurstueck
failed or partially failed: Download of features failed: Error

ALKIS-data, especially parcels are usually restricted to be displayed for scale larger than 1:5000, maybe 1:10000, due to the workload they put on the server and the amount of data which needs to be downloaded/transfered.

Try to grab smaller areas, maybe single "Fluren" will work.
