Available transformations
to EPSG:4326
EPSG:4326 - WGS 84

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Derived at two points, checked at a third by Stolt Comex Seaway and Geoid for Elf.

Information source: TotalFinaElf

Revision date: 2020-03-14

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: Manoca 1962

Datum: Manoca 1962

Ellipsoid: Clarke 1880 (IGN)

Prime meridian: Greenwich

Data source: EPSG

Information source: TotalFinaElf

Revision date: 2004-01-06

Scope: Geodesy.

Remarks: Replaces Doula 1948 (code 4192). The intent of the Bukavu 1953 conference was to adopt the Clarke 1880 (RGS) ellipsoid (code 7012) but in practice this CRS has used the IGN version.

Area of use: Cameroon - coastal area.

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

Center coordinates
9.43 3.58

WGS84 bounds:
8.45 2.16
10.4 4.99

Cameroon - coastal area.
