Name: HD72 to WGS 84 (2)
Method: Geocentric translations (geog2D domain)
Remarks: Derived at fundamental point Szolohegy and tested at 99 stations throughout Hungary. Accuracy better than 1m in all three dimensions throughout Hungary. OGP recommends use of newer transformation (tfm code 1242) in preference to this transformation.
