EPSG:4199

Egypt 1930

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: Egypt 1930

Datum: Egypt 1930

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: EPSG

Revision date: 2004-01-06

Scope: Geodesy.

Remarks: Note that Egypt 1930 uses the International 1924 ellipsoid, unlike the Egypt 1907 CRS (code 4229) which uses the Helmert ellipsoid. Oil industry references to the Egypt 1930 name and the Helmert ellipsoid probably mean Egypt 1907.

Area of use: Egypt - onshore.

Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
