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

Available transformations:

Selected transformation

NO DEFAULT TRANSFORMATION

Attributes

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
