[gdal-dev] NetCDF config option for west > east?

[Markus Metz]

I have a NetCDF file with west > east, gdalinfo reports
Corner Coordinates:
Upper Left  (     335.257,      70.000)
Lower Left  (     335.257,      30.000)
Upper Right (  44.7424710,  69.9999970)
Lower Right (  44.7424710,  29.9999954)
Center      (     190.000,      50.000)

west =  335.257 > east = 44.7424710

The reason is that west has been wrapped such that it is in the range [0,
360], and GDAL thinks that columns need to be read from right to left
instead of left to right.

The fix is to convert west with west -= 360, then assign corrected extents
with gdal_translate -a_ullr

There is a config option GDAL_NETCDF_BOTTOMUP. Could something similar be
implemented for west > east, something like GDAL_NETCDF_LEFTISLEFT? Or is
it a corrupted file and manual correction is the only option?
