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.
