Name: Amersfoort to ETRS89 (1)
Method: Coordinate Frame rotation (geog2D domain)
Remarks: Replaced by Amersfoort to ETRS89 (3) (tfm code 15739). Dutch sources also quote an equivalent transformation using the Molodenski-Badekas 10-parameter method (M-B) - see tfm code 1066.
Information source: http://www.rdnap.nl/ Also Nederlandse Commissie voor Geodesie publication 30; 3rd edition 1997. Also with change of method and parameter units at EuroGeographics; http://crs.bkg.bund.de/crs-eu/
Revision date: 2023-01-17
Unit: metre
Geodetic CRS: Amersfoort
Datum: Amersfoort
Ellipsoid: Bessel 1841
Prime meridian: Greenwich
Data source: EPSG
Information source: NSGI: Netherlands Partnership of Kadaster, Rijkswaterstaat and Hydrographic Service, http://www.nsgi.nl/.
Revision date: 2026-01-06
Scope: Cadastre, engineering survey, topographic mapping.
Remarks: Replaces 28991 (RD Old). Since 2000-10-01 has been redefined as derived from ETRS89 by application of the official transformation RDNAPTRANS(TM). Since 2008 use has been extended from onshore to offshore through the RDNAPTRANS(TM) transformation.
Area of use: Netherlands - onshore and offshore.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (x,y). Orientations: east, north. UoM: m.
