| MolodenskiTransform | | public class MolodenskiTransform extends AbstractMathTransform implements Serializable(Code) | | Two- or three-dimensional datum shift using the (potentially abridged) Molodensky transformation.
The Molodensky transformation (EPSG code 9604) and the abridged Molodensky transformation (EPSG
code 9605) transform two or three dimensional geographic points from one geographic coordinate
reference system to another (a datum shift), using three shift parameters (delta X, delta Y,
delta Z) and the difference between the semi-major axis and flattenings of the two ellipsoids.
Unlike the Bursa-Wolf 3 parameter method (which acts on geocentric coordinates),
this transformation can be performed directly on geographic coordinates.
