Name: Pulkovo 1942 to Georgia Geodetic Datum (1)
Method: Coordinate Frame rotation (geog2D domain)
Remarks: Derived at 16 stations. Replaces transformation derived at 9 stations given in "Methodology and Parameters for Datum Transformation between the New and Old Reference Systems", European Union ENPI Programme for Georgia National Agency of Public Registry (NAPR), Ministry of Justice of Georgia, November 14th 2013. Note: information source states that the Helmert formula use the Position Vector convention, but using the station coordinates tabulated in the report IOGP believes that the parameter values are consistent with use of the coordinate frame rotation convention.
