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.
