EPSG:11480

Amersfoort to ETRS89-NLD [AGRS2010] (8)

Attributes

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, https://www.nsgi.nl/

Revision date: 2026-07-21

Scope: Transformation of coordinates at 0.25m level of accuracy.

Remarks: Approximation to 25cm of the horizontal component of the official transformation (see CT 11481). Used with an ellipsoidal height of 0m in Amersfoort or 43m in ETRS89 and with an additional correction grid (up to 0.25m). Replaces Amersfoort to ETRS89 (5) and (6) (CT codes 4830 and 4831).

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Netherlands - onshore and offshore.
