EPSG:3368

IGN Astro 1960 / UTM zone 29N

Attributes

Unit: metre

Geodetic CRS: IGN Astro 1960

Datum: IGN Astro 1960

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: EPSG

Information source: OGP

Revision date: 2006-03-16

Scope: Topographic mapping (small scale).

Remarks: Mining title descriptions referring only to "Clarke 1880 ellipsoid, UTM zone 29" should be assumed to be referenced to this CRS. Oil industry considers "Mauritanian Mining Cadastre 1999 / UTM zone 29N" to be exactly defined through tfm code 15858.

Area of use: Mauritania - between 12°W and 6°W.

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