Implements the wish of #6195 to assume a regular grid NetCDF in a reasonable longitude/latitude range adopts the
OGC:CRS84
crs, when all prior attempts to find one have failed.GDAL_NETCDF_ASSUME_LONGLAT
default NO, set to YES to apply the crsASSUME_LONGLAT
same as config optionGDAL_NETCDF_ASSUME_LONGLAT
There is a python test on
netcdf/trmm-nc2.nc
that invokes the use of the setting (this file otherwise doesn't have a crs set).What are related issues/pull requests?
#6195
Example
here on a remote file, provides a CRS OGC:CRS84 only if the config option is set
examples to invoke option control and overrides
Note that this flollowing file doesn't benefit from the assumption, because its geotransform puts it (just) outside the required range. A possible offshot TODO for me for the VRT driver 'vrt://...?a_ullr', or we could expand the bounds allowed.
