IGN Astro 1960 / UTM zone 30N to WGS 84 / 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: OGP

Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Remarks: Transformation taken from IGN Astro 1960 / UTM zone 30N to Mauritania 1999 / UTM zone 30N (1) (tfm code 15859) assuming that Mauritania 1999 is equivalent to WGS 84 within the accuracy of this tfm.

Method: Affine parametric transformation

Area of use: Mauritania - east of 6°W.
