Geodetic CRS: CGRS93
Datum: Cyprus Geodetic Reference System 1993
Ellipsoid: WGS 84
Prime meridian: Greenwich
Data source: EPSG
Information source: Cyprus Department of Lands and Surveys (DLS).
Revision date: 2015-10-17
Scope: Hydrography and aeronautical charting.
Remarks: Parameter values from CGRS93 to ETRS89 (1) (code 7444). Approximation at the +/- 1m level assuming that ETRS89 is equivalent to WGS 84.
Method: Position Vector transformation (geog2D domain)
Area of use: Cyprus - onshore.
