EPSG:4833

Amersfoort to WGS 84 (4)

Attributes

Geodetic CRS: Amersfoort

Datum: Amersfoort

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: OGP

Revision date: 2023-01-17

Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.

Remarks: Parameter values from Amersfoort to ETRS89 (5) (tfm code 4830) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the transformation. Replaces Amersfoort to WGS 84 (3) (code 15934).

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Netherlands - onshore, including Waddenzee, Dutch Wadden Islands and 12-mile offshore coastal zone.

Description: (565.4171, 50.3319, 465.5524, 1.9342, -1.6677, 9.1019, 4.0725)
