Ellipsoid: Clarke 1880 (RGS)
Prime meridian: Greenwich
Data source: OGP
Information source: Various industry sources.
Revision date: 2006-01-03
Scope: Coastal hydrography.
Remarks: A variation of this datum has been adopted by the oil industry but incorrectly using the International 1924 ellipsoid and not tied to the official Portuguese triangulation - see Mhast (onshore) and Mhast (offshore) (codes 6704 and 6705).
Area of use: Angola - Cabinda.
