Frank,
Wouldn't this apply to the netCDF grids as well? GMT has always made the
distinction on the area vs point representation. The grids created by
GMT hold that information on the global attribute "node_offset". As for
other netCDF CF grids created elsewhere it is also possible to find
which model is used by checking the grid limits vs array size because
for the same limits the PixelIsArea model has one less row and column
than the PixelIsPoint.
Joaquim,
The gdal/frmts/netcdf/gmtdataset.cpp code already examines the node_offset
and adjusts the geotransform accordingly. It does not currently attempt
to expose the node_offset via the AREA_OR_POINT metadata item though it
could.
I do not see the GMT format driver being pertinent to the RFC.
Best regards,
