  • Bulgaria - onshore. , accuracy 5.0 m, code 7806 (default) [7]

Selected transformation

Method: Molodensky-Badekas (PV geog2D domain)

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.
