Geodetic datum transformation examples (NZGD1949 to NZGD2000)

The following table provides examples of the transformation of 3 points using the different datum transformation methods. These show the transformation from NZGD1949 to NZGD2000 but they can also be used to transform from NZGD2000 to NZGD1949. These example points can be used to verify that the transformation between datums has been performed correctly.
