EPSG:1053

NTF to RGF93 (1)

Attributes

Geodetic CRS: NTF

Datum: Nouvelle Triangulation Francaise

Ellipsoid: Clarke 1880 (IGN)

Prime meridian: Greenwich

Data source: OGP

Information source: Institut Geographique National (IGN) document NTG_88.pdf, "Grille de parametres de transformation de coordonnees". http://www.ign.fr

Revision date: 2010-03-30

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

Remarks: May be used for transformation of NTF to/from ETR89 and WGS 84 as RGF93 may be considered equivalent to ETRS89 or WGS 84 within the accuracy of the transformation. See tfm codes 1054 and 15939. May be emulated using NTv2 method - see tfm code 15958.

Method: France geocentric interpolation

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