  • Russian Federation - onshore and offshore. , accuracy 1.0 m, code 9773 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: For many purposes GSK-2011 can be considered to be coincident with WGS 84. This approximation ignores the low accuracy of the WGS 84 ensemble and the application of tectonic plate motion to WGS 84 data.
