All Implemented Interfaces:

CoordinateOperation, WithEpsgGOperationMethod

public class PositionVectorTransformation
extends Object
implements CoordinateOperation, WithEpsgGOperationMethod

The Position Vector transformation ( a 7-parameter Helmert Transformation in the geocentric domain). This implements the EPSG 1033 method It is used to perform the TOWGS84 transforms. Created by Karel Maesen, Geovise BVBA on 21/07/17.
