cf.CoordinateReference.identities

CoordinateReference.identities(generator=False, **kwargs)[source]

Returns all possible identities.

The identities comprise:

  • The standard_name coordinate conversion parameter, preceded by 'standard_name:'.

  • The grid_mapping_name coordinate conversion parameter, preceded by 'grid_mapping_name:'.

  • The netCDF variable name (corresponding to a netCDF grid mapping variable), preceded by 'ncvar%'.

New in version (cfdm): 1.7.0
