Name: Amersfoort to ETRS89 (1)
Method: Coordinate Frame rotation (geog2D domain)
Remarks: Dutch sources also quote an equivalent transformation with parameter values dX=+593.032 dY=+26.000 dZ=+478.741m, rX rY rZ and dS as this tfm. These values belong to a different transformation method and cannot be used with the Coordinate Frame method.

Scope: Topographic mapping (medium and small scale).
Remarks: Used as a common CRS for the Baltic states and for medium and small scale mapping since 1993. For large scale applications see CRS codes 3300 and 3301 (Estonia), 3059 and 10306 (Latvia), and 2600 (Lituania).
Area of use: Estonia, Latvia and Lithuania - onshore and offshore.
Coordinate system: Cartesian 2D CS. Axes: northing, easting (X,Y). Orientations: north, east. UoM: m.
