Covered area powered by MapTiler MapTiler logo

Center coordinates
5.20814797 52.22536978

WGS84 bounds:
3.2 50.75

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

Available transformations:

Selected transformation

Netherlands

code 15934

Accuracy 1.0 m
7 parameters

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

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
