Direct Known Subclasses:

ConcatenatedTransform, DirectTransform, GeocentricTransform, MatrixTransform, NotSupportedTransformation, ProjectionTransform

public abstract class CRSTransformation
extends Transformation

The change of coordinates from one CRS to another CRS based on different datum is 'currently' only possible via a coordinate Transformation.

The transformation parameters could only be derived empirically by a set of points common to both coordinate reference systems it means by identical points. Choice, allocation, number and the quality of coordinates of the points affect extensive the results and the accuracy. Therefore different realizations for transformations from one datum to another exist.
