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
