Name: NEA74 Noumea to RGNC91-93 (3)
Method: Geocentric translations (geog2D domain) by grid (IGN)
Grid Files: gr3dnc03a.mnt
Remarks: Developed in July 2002 and officially adopted in August 2005. May be emulated using NTv2 method - see RGNC91-93 to NEA74 Noumea (4) (code 1295).

Revision date: 2020-03-14
Unit: metre
Geodetic CRS: NEA74 Noumea
Datum: NEA74 Noumea
Ellipsoid: International 1924
Prime meridian: Greenwich

Revision date: 2006-07-21
Scope: Engineering survey, topographic mapping.
Remarks: Replaced by RGNC91-93 / Lambert Caledonie (CRS code 3163). Variant of NEA74 Noumea / Noumea Lambert (CRS code 3166) with defining parameters at integer seconds: gives identical conversion results.
Area of use: New Caledonia - Grande Terre - Noumea district.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
