Name: NEA74 Noumea to RGNC91-93 (4)
Method: NTv2
Grid Files: RGNC1991_NEA74Noumea.gsb
Remarks: Emulation using NTv2 method of tfm NEA74 Noumea to RGNC91-93 (3) (code 15943).
Information source: ESRI
Revision date: 2007-07-06
Unit: metre
Geodetic CRS: NEA74 Noumea
Datum: NEA74 Noumea
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: Service Topographique de la Nouvelle Caledonie, Direction des Infrastructures, de la Topographie et des Transports Terrestres. www.dittt.gouv.nc
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.
