EPSG:6307

Nord Sahara 1959

Attributes

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: OGP

Information source: "Le System Geodesique Nord-Sahara"; IGN Paris

Revision date: 2012-04-18

Scope: Topographic mapping.

Remarks: Adjustment includes Morocco and Tunisia but use only in Algeria. Within Algeria the adjustment is north of 32°N but use has been extended southwards in many disconnected projects, some based on independent astro stations rather than the geodetic network.

Area of use: Algeria - onshore and offshore.
