EPSG:4237

HD72

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Parameter values taken from HD72 to ETRS89 (1) (code 1829) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the transformation. OGP recommends use of newer MSZ 7222 equivalent (tfm code 1448) in preference to this transformation.
