EPSG:7445 DEPRECATED

CGRS93 to WGS 84 (1)

Attributes

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.
