Method: Geocentric translations (geog2D domain)
Remarks: Parameter values from CH1903+ to ETRS89 (tfm code 1647). In EPSG db v5.2 to v8.9 given to 1dm; the difference in output of cms is considered by swisstopo to be insignificant given the tfm accuracy. Superseded by CH1903 to ETRS89 (2) (tfm code 7674).
