Well, Function might be helpful then (and happily ignored by code that assumes
that usual
raster order will be used). However I'm not sure in which way GDAL is involved
in this
discussion :-) Regarding GMLJP2, GDAL will ignore Function on reading it, and
not write it. So
I think that on the read side, that should be OK in practice. So, there could
potentially be
issues on the write side for rasters generated by GDAL and read by other
software that
would assume that a georeferencing with Lat Long order would imply the raster
first axis to
be Lat ? Or perhaps issues in the GDAL WCS client ? Perhaps Jukka could give
more precisions
if there are actual interoperability problems.
