[Qgis-user] Problem with axis order of WMS

[Robert Nuske]

Hi Bernhard

The bug report you cite seems to describe the same problem but for QGIS web 
client and QGIS Server. Looking again in the bug tracker I just found 
http://hub.qgis.org/issues/9345 
There is even recent work on that issue:  Alvaro Huarte offered a patch and 
Jürgen Fischer added  it to master 6 days ago


I tested it using packages from ubuntugis-nightly on ubuntu quantal and the 
WMS http://sg.geodatenzentrum.de/wms_dtk_bkg with EPSG:31467.

It works nicely  -> Thanks a lot for fixing!
Now awaiting eagerly Version 2.2 to point my colleagues to


If just someone would have droped a line on qgis-user list...


cheers,
  robert
