[gdal-dev] WFS Axis order issue with projected coordinate system

Thanks Even.

So does this ticket account for this problem?


Or do changes need to be applied in the WFS driver as well?

Yes the ISO/OGC people have made my job very hard here in NZ. As NZ's leading geospatial government department LINZ is tasked with pushing OGC standards to get interoperability going. But with all of NZ's 50+ projections being defined as Northing, Easting it's making it very hard to push with users. Because most WFS service talk the highest available version by default, it hard to get users to use and understand why they must use version 1.0.0. BTW it was a mistake that the axis order was set as North, East for NZ projections. In the EPSG submission it was not explicitly specified, rather EPSG inferred it!

This is http://trac.osgeo.org/gdal/ticket/4329

In short, the WFS/GML drivers can deal with geographic SRS that have
latitude/longitude ordering and do the coordinate swapping, but not yet for
projected SRS that have northing/easting ordering.

The return of the driver is somehow correct.  It reports a SRS in
northing/easting ordering and presents coordinates in that order. But I agree
it would be nicer for it to behave like geographic SRS with inverted axis

Another way of working around that is to force VERSION=1.0.0, since GeoServer
only honours EPSG axis order from WFS 1.1.0. Remembers me
