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
Revision date: 2016-04-27
Scope: Geodesy, engineering survey, topographic mapping.
Remarks: Official transformation for converting existing geodetic and cartographic materials to BGS2005. Older CRSs (CS30, CS50, CS70) must first be transformed to Pulkovo 1942(83) before this transformation is applied.
Method: Molodensky-Badekas (PV geog2D domain)
Area of use: Bulgaria - onshore.
