Method: Coordinate Frame rotation (geog2D domain)
Remarks: Parameter values from Amersfoort to ETRS89 (3) (tfm code 15739) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the transformation. Replaces Amersfoort to WGS 84 (2) (code 1672). Replaced by Amersfoort to WGS 84 (4) (tfm code 4833).
Information source: OGP
Revision date: 2009-11-24
Unit: degree (supplier to define representation)
Geodetic CRS: Amersfoort
Datum: Amersfoort
Ellipsoid: Bessel 1841
Prime meridian: Greenwich
Data source: OGP
Information source: http://www.rdnap.nl/
Revision date: 2015-02-12
Scope: Geodetic survey.
Remarks: Since 1 October 2000 Amersfoort geodetic datum has been redefined; it is derived from ETRS89 by application of the official transformation RDNAPTRANS(TM). Transformation Amersfoort to ETRS89 (7) (code 7000) approximates RDNAPTRANS(TM) to 0.001 m.
Area of use: Netherlands - onshore, including Waddenzee, Dutch Wadden Islands and 12-mile offshore coastal zone.
Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree
