IGN Astro 1960 / UTM zone 30N to Mauritania 1999 / UTM zone 30N (1)

Attributes

Geodetic CRS: IGN Astro 1960

Datum: IGN Astro 1960

Ellipsoid: Clarke 1880 (RGS)

Prime meridian: Greenwich

Data source: EPSG

Information source: "Resultats des calculs de la campagne geodesique realisee dans le cadre du projet du cadastre minier", Direction de la Topographie et de la Cartographie, July 1999.

Revision date: 2006-03-16

Scope: Minerals management (including oil and gas exploration and production).

Remarks: Parameter values consistent with the OGP Affine parametric transformation method derived by OGP from the published Helmert 2D parameter values. May be used for transformations to WGS 84 - see tfm code 15863.

Method: Affine parametric transformation
