Interface ParametricDatum

All Superinterfaces:

Datum, IdentifiedObject

@UML(identifier="ParametricDatum",
     specification=ISO_19111)
public interface ParametricDatum
extends Datum

Identification of a particular reference surface used as the origin of a parametric coordinate system. The identification includes the frame position with respect to the Earth or other planet. It may be a textual description and/or a set of parameters.

Method Details

getDatumDefiningParameter

@UML(identifier="datumDefiningParameter",
     obligation=OPTIONAL,
     specification=ISO_19111)
default Optional<ParameterValueGroup> getDatumDefiningParameter()

Parameters used to define the parametric datum. Each parameter can be a parameter value, an ordered sequence of values, or a reference to a file of parameter values that define a parametric datum.

Returns:

parameter used to define the parametric datum.

Departure from OGC/ISO standard for harmonization between different specifications

ISO 19111 defines a DefiningParameter class. GeoAPI retrofits in the org.opengis.parameter framework.
