Spatial Properties Some entities are of spatial nature, in these cases, the entity will have a set of properties related to the coordinate system used by the entity. The following table lists these properties: coord_hdatum Contains the horizontal datum for the Coordinate Reference Systems (CRS). These are the types currently supported:   wgs72 World Geodetic System 1972 (WGS 72) wgs84 World Geodetic System 1984 (WGS 84) grs80 Geodetic Reference System 1980 (GRS 80) nad27 North American Datum 1927 (NAD27) nad83 North American Datum (NAD83) nad83_2011 North American Datum (NAD83 2011) nad83_harn North American Datum (NAD83 HARN) nad83_csrs North American Datum (NAD83 CSRS) gda94 Geocentric Datum of Australia 1994 (GDA94) etrs89 European Terrestrial Reference System 1989 (ETRS89) agd66 Australian Geodetic Datum 1966 (AGD66) clarke80 Modified Clarke 1880 coord_origin_x Contains the coordinate of axis X for the origin of the project. coord_origin_y Contains the coordinate of axis Y for the origin of the project. coord_origin_z Contains the coordinate of axis Z for the origin of the project. coord_projection Contains the data projection for the Coordinate Reference Systems (CRS).
