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.

@UML(identifier="operationVersion",

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.
