044 * The change of coordinates from one CRS to another CRS based on different datum is 'currently' only possible via a
045 * coordinate <code>Transformation</code>.
046 * <p>
047 * The transformation parameters could only be derived empirically by a set of points common to both coordinate
048 * reference systems it means by identical points. Choice, allocation, number and the quality of coordinates of the
049 * points affect extensive the results and the accuracy. Therefore different realizations for transformations from one
050 * datum to another exist.
