public interface Transformation
extends SingleOperation
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.

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.

Returns:
The coordinate operation version.
