Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Parameter values from BD72 to ETRS89 (2) (code 15928) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the tfm. Scale difference is given by information source as -1.0000012747; given in this record in ppm to assist application usage.

Attributes

Unit: metre

Geodetic CRS: BD72

Datum: Reseau National Belge 1972

Ellipsoid: International 1924

Prime meridian: Greenwich

Data source: EPSG

Information source: IGN Brussels; www.ngi.be/

Revision date: 2021-06-17

Scope: Engineering survey, topographic mapping.

Remarks: Replaces 21500 (BD50 / Belge Lambert 50). An alternative - BD72 / Belgian Lambert 72 (code 31370) - was introduced in 2000 to use the standard Lambert Conic Conformal (2SP) projection method (code 9802). EPSG recommends this alternative.

Area of use: Belgium - onshore.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (X,Y). Orientations: east, north. UoM: m.
