Hi all, PROJ.4 trunk supports a new parameter "+axis" for projection strings to define axis orientation. With this you can, for example, create an "upside-down" projection by specifying "+axis=wsu" in your projection string. (See http://trac.osgeo.org/proj/wiki/GenParms#Axisorientation )
I am trying to use this to create south-up hillshade images. I compiled PROJ.4 trunk and GDAL using --with-static-proj4=/usr/local (where my PROJ.4 is installed), but gdalwarp seems to just ignore the new parameter - the result is the same as with the north-up projection. Can anyone tell me if this is supposed to work and there's just something wrong with my build, or if there is a limitation in GDAL that prevents it from working with upside-down projections? Also if you can give me any pointers to code where this limitation may be fixed I may be able to contribute a patch, if the solution is not too involved.
