Engineering survey, topographic mapping.
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.
New Caledonia - Grande Terre - Noumea district.
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
