Geodetic CRS: HD72
Datum: Hungarian Datum 1972
Ellipsoid: GRS 1967
Prime meridian: Greenwich
Data source: OGP
Information source: Timar and Molnar, "Standardization problems of the HD72 to ETRS89 transformation" in Geodezia es Kartografia 54(12):28-30. www.fomi.hu/internet/magyar/szaklap/geodkart.htm
Revision date: 2008-08-02
Scope: Throughout Hungary the average horizontal error of the transformation is 0.19 m, the maximum is 0.41 m.
Remarks: Derived at 1153 stations of the Hungarian National GPS Network. Values here correct parameter errors given in Hungarian standard MSZ 7222:2002. Replaces HD72 to ETRS89 (1), code 1829. May be taken as approximate tfm HD72 to WGS 84 - see tfm code 1448.
Method: Coordinate Frame rotation (geog2D domain)
Area of use: Hungary.
