LUREF / Luxembourg TM (3D)

Attributes

Unit: metre

Geodetic CRS: LUREF

Datum: Luxembourg Reference Frame

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: EPSG

Information source: Administration du Cadastre et de la Topographie (ACT), https://act.public.lu

Revision date: 2022-01-03

Scope: Cadastre, topographic mapping.

Remarks: The height error in assuming that the CS is Cartesian never exceeds 2mm per 100m height in Luxembourg. The ellipsoidal height approximates NG95 height to 5-15cm. For engineering and other applications requiring physical height use compound CRS code 9897.

Area of use: Luxembourg.

Coordinate system: Affine 3D CS. Axes: northing, easting, ellipsoidal height (X,Y,h). Orientations: north, east, up. UoM: m.
