EPSG:7806

Pulkovo 1942(83) to BGS2005 (1)

Attributes

Geodetic CRS: Pulkovo 1942(83)

Datum: Pulkovo 1942(83)

Ellipsoid: Krassowsky 1940

Prime meridian: Greenwich

Data source: EPSG

Information source: Ministry of Regional Development and Public Works instruction № RD-02-20-12 of August 3, 2012
