EPSG:9882

RGF93 v1 to RGF93 v2 (1)

Attributes

Geodetic CRS: RGF93 v1

Datum: Reseau Geodesique Francais 1993 v1

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: IOGP

Revision date: 2021-11-04

Scope: Transformation of coordinates at 0.05m level of accuracy.

Remarks: Maximum differences are 0.1m in both horizontal and vertical. Distortions in RGF93 v1 are irregular and IGN considers that no systematic transformation to the improved v2 adjustment is possible.

Method: Geocentric translations (geog2D domain)

Area of use: France - onshore and offshore, mainland and Corsica (France métropolitaine including Corsica).
