Interface Transformation

All Superinterfaces:

CoordinateOperation, IdentifiedObject, Operation, SingleOperation

@UML(identifier="CC_Transformation",
     specification=ISO_19111)
public interface Transformation
extends Operation

An operation on coordinates that usually includes a change of Datum. The parameters of a coordinate transformation are empirically derived from data containing the coordinates of a series of points in both coordinate reference systems. This computational process is usually "over-determined", allowing derivation of error (or accuracy) estimates for the transformation. Also, the stochastic nature of the parameters may result in multiple (different) versions of the same coordinate transformation.

Method Detail

getOperationVersion

@UML(identifier="operationVersion",
     obligation=MANDATORY,
     specification=ISO_19111)
java.lang.String getOperationVersion()

Version of the coordinate transformation (i.e., instantiation due to the stochastic nature of the parameters). This attribute is mandatory in a Transformation.

Specified by:

getOperationVersion in interface CoordinateOperation

Returns:

The coordinate operation version.
