EPSG:6704

Mhast (onshore)

Attributes

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: OGP

Information source: ChevronTexaco.

Revision date: 2006-01-03

Scope: Oil industry exploration and production. From 1979, offshore use superseded by Mhast (offshore) (code 6705).

Remarks: Adopted by oil industry with intention of being Mhast 1951 (code 6703) but incorrectly (for Mhast 1951) used the International 1924 ellipsoid. This datum differs by about 400 metres from the Portuguese Mhast 1951 and Camacupa datums.

Area of use: Angola (Cabinda) - onshore and offshore; The Democratic Republic of the Congo (Zaire) - onshore coastal area and offshore.
