Interface TemporalCRS

All Superinterfaces:

CoordinateReferenceSystem, IdentifiedObject, ReferenceSystem, SingleCRS

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

A 1-dimensional CRS used for the recording of time. Any CRS can be associate with a temporal CRS to form a spatio-temporal CompoundCRS. More than one temporal CRS may be included if these axes represent different time quantities.

Permitted coordinate systems

This type of CRS can be used with coordinate systems of type TimeCS only.

Since:

1.0

Method Details

getCoordinateSystem

@UML(identifier="coordinateSystem",
     obligation=MANDATORY,
     specification=ISO_19111)
TimeCS getCoordinateSystem()

Returns the coordinate system, which shall be temporal.

Specified by:

getCoordinateSystem in interface CoordinateReferenceSystem

Specified by:

getCoordinateSystem in interface SingleCRS

Returns:

the temporal coordinate system.

getDatum

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

Returns the datum, which shall be temporal. 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 temporal datum, 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="datum",
     obligation=CONDITIONAL,
     specification=ISO_19111)
default DatumEnsemble<TemporalDatum> getDatumEnsemble()

Returns the datum ensemble, which shall have temporal datum members. 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.
