Replaces use of UTM with older 2D systems IGN72 Grande Terre, IGN56 Lifou, ST87 Ouvea, IGN53 Mare, ST84 Ile des Pins, ST71 Belep and NEA74 Noumea (CRS codes 2981, 2995-98, 3060, 3164). Replaced by RGNC15 / Lambert New Caledonia 2015 (CRS code 10314).
New Caledonia - Belep, Grande Terre, Ile des Pins, Loyalty Islands (Lifou, Mare, Ouvea).
Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
