Parameter: geodeticDatum

Short Description: Geodetic Datum (spatial reference system) for coordinates

Short Name: geodeticDatum

Official Name: geodeticDatum

Description

Definition The ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geographic coordinates given in latitude and longitude.

Notes Recommended best practice is to use the EPSG code of the SRS, if known. Otherwise use a controlled vocabulary for the name or code of the geodetic datum, if known. Otherwise use a controlled vocabulary for the name or code of the ellipsoid, if known. If none of these is known, use the value unknown. This term has an equivalent in the dwciri: namespace that allows only an IRI as a value, whereas this term allows for any string literal value.

If this term is used in DarwinCore (dwc:geodeticDatum) is the ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geographic coordinates given in dwc:decimalLatitude and dwc:decimalLongitude are based.
