Available transformations
to EPSG:4644
EPSG:4644 - NEA74 Noumea

Selected transformation

Method: NTv2

Grid Files: RGNC1991_IGN72GrandeTerre.gsb

Remarks: Emulation using NTv2 method of tfm NEA74 Noumea to RGNC91-93 (3) (code 15943). Note reversal of sign of parameter values in grid file.

Unit: metre

Geodetic CRS: RGNC91-93

Datum: Reseau Geodesique de Nouvelle Caledonie 91-93

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Revision date: 2023-03-31

Scope: Engineering survey, topographic mapping.

Remarks: Used for EEZ and uninhabited islands. For Grande-Terre, Isle de Pins, Belep and Loyalty Islands (Lifou, Mare, Ouvea) use RGNC91-93 / Lambert New Caledonia (CRS code 3163) rather than this CRS. Replaced by RGNC15 / UTM zone 58S (CRS code 10316).

Area of use: New Caledonia - between 162°E and 168°E onshore and offshore.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
