Geodetic CRS: ELD79
Datum: European Libyan Datum 1979
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: TotalFinaElf
Revision date: 2020-03-14
Scope: Oil and gas exploration and production.
Remarks: Derived by Geoid in 2000 from ITRF connection by NAGECO for TotalFinaElf. For historic compatibility TFE use the 1994 tfm ELD79 to WGS 84 (3) (code 1861) rather than this transformation.
Method: Position Vector transformation (geog2D domain)
Area of use: Libya - Mabruk field.
