EPSG:15939

NTF to WGS 84 (2)

Attributes

Geodetic CRS: NTF

Datum: Nouvelle Triangulation Francaise

Ellipsoid: Clarke 1880 (IGN)

Prime meridian: Greenwich

Data source: OGP

Information source: OGP

Revision date: 2010-03-30

Scope: For applications requiring an accuracy of better than 1 metre.

Remarks: These parameter values are taken from NTF to RGF93 (1) (code 1053) as RGF93 may be considered equivalent to WGS 84 within the accuracy of the transformation. May be emulated using NTv2 method - see tfm code 15960.

Method: France geocentric interpolation

Area of use: France - onshore - mainland and Corsica.
