Scope: Engineering survey, topographic mapping.
Remarks: Replaces Combani 1950 / UTM zone 38S (CRS code 2980) except for cadastre which uses Cadastre 1997 / UTM zone 38S (CRS code 5879). Replaced by RGM23 / UTM zone 38S (CRS code 10674) with effect from 2023-01-01 except for cadastre.
Area of use: Mayotte - onshore and offshore.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
