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? Markus M
