EPSG:4326 - WGS 84

Selected transformation

Remarks:

Information source:

Revision date: 2020-03-14

Steps of transformation: 1881 1130

Attributes

Unit: kilometre

Geodetic CRS: Carthage (Paris)

Datum: Carthage (Paris)

Ellipsoid: Clarke 1880 (IGN)

Prime meridian: Paris

Data source: EPSG

Information source: OGP

Revision date: 2013-06-12

Steps of transformation: 1881 1130

Scope: Minerals management (including oil and gas exploration and production).

Remarks: CAUTION: Carthage datum did not exist when the 1953 decree was issued and an inference is that grid should be applied to the Voirol 1875 geogCRS. Common practice assumes that the current Tunisian geodetic datum of Carthage applies.

Area of use: Tunisia - onshore.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: km.
