Method: Geocentric translations (geog2D domain)
Remarks: Parameters values from CH1903 to ETRS89 (1) (tfm code 1646) assuming ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. Replaces CH1903 to WGS 84 (1) (code 1753). Replaced by CH1903 to WGS 84 (3) (code 7788).
