I try to load a WFS including a bbox parameter via PyQGIS. The WFS is loaded without problems, but unfortunately the bbox parameter does not work. If the bbox parameter is added to the query I get all the results, including the results that are outside of the bbox range. When I start the request in the browser or using the QGIS GUI, I get the correctly filtered features. It looks like PyQGIS does not take into account the bbox parameter.

My code looks like this:

vl = QgsVectorLayer("https://wxs.ign.fr/administratif/geoportail/wfs?VERSION=2.0.0&TYPENAMES=ADMINEXPRESS-COG-CARTO.LATEST:arrondissement&COUNT=1000&SRSNAME=EPSG::4326&BBOX=42.374778,-2.109375,47.115000,2.856445", 'water', 'WFS')

Is this a known bug or something missing in my request?

As already said, in the browser or via the QGIS GUI the request works, but not with PyQGIS.

  • QGIS Version is 2.18.18

  • It's difficult to see how PyQGIS doesn't take BBOX into account, since the request is processed on the server and results returned to you. Looking at the WFS 1.0.0 spec, it appears that SRS is not used on a BBOX, and I have a feeling that only one CRS is supported too, which is why there's no need for CRS/SRS in the BBOX! You say the query works in QGIS so perhaps QGIS is sending a WFS 1.1.0 request?

You must give the bbox srs as well.

vl = QgsVectorLayer("http://geoserver_url/ows?style=&request=GetFeature&service=WFS&version=1.0.0&typeName=dataset:water&bbox=3562017.31020000018179417,5679733.8194363797083497,3563253.31000480009242892,5681088.4972945200279355,EPSG:31467&srsname='EPSG:31467'", 'water', 'WFS')
  • Thanks for the tip, unfortunately that does not work either.
