Interface GeodeticCRS

All Superinterfaces:

CoordinateReferenceSystem, IdentifiedObject, ReferenceSystem, SingleCRS

All Known Subinterfaces:

GeocentricCRS, GeographicCRS

@UML(identifier="GeodeticCRS",
     specification=ISO_19111)
public interface GeodeticCRS
extends SingleCRS

A 2- or 3-dimensional CRS used over the whole planet or substantial parts of it. This is used to describe large portions of the planet's surface up to the entire planet's surface. If the geodetic reference frame is dynamic then the geodetic CRS is dynamic, else it is static.

Permitted coordinate systems

This type of CRS can be used with coordinate systems of type CartesianCS, SphericalCS or EllipsoidalCS. In the latter case, the GeographicCRS specialization should be used.

Method Details

getDatum

@UML(identifier="datum",
     obligation=CONDITIONAL,
     specification=ISO_19111)
GeodeticDatum getDatum()

Returns the reference frame, which shall be geodetic. This property may be null if this CRS is related to an object identified only by a datum ensemble.

Specified by:

getDatum in interface SingleCRS

Returns:

the reference frame, or null if this CRS is related to an object identified only by a datum ensemble.

Condition:

Mandatory if the datum ensemble is not documented.

getDatumEnsemble

@UML(identifier="datumEnsemble",
     obligation=CONDITIONAL,
     specification=ISO_19111)
default DatumEnsemble<GeodeticDatum> getDatumEnsemble()

Returns the datum ensemble, whose members shall be geodetic reference frames. This property may be null if this CRS is related to an object identified only by a single datum.

The default implementation returns null.

Specified by:

getDatumEnsemble in interface SingleCRS

Returns:

the datum ensemble, or null if this CRS is related to an object identified only by a single datum.

Since:

3.1

Condition:

Mandatory if the datum is not documented.
