Geodetic CRS: KKJ
Datum: Kartastokoordinaattijarjestelma (1966)
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: National Land Survey of Finland; http://www.maanmittauslaitos.fi
Revision date: 2025-01-21
Scope: Transformation of coordinates at 0.03m level of accuracy.
Remarks: Recommended transformation between KKJ and EUREF-FIN. Use this in preference to transformation KKJ to EUREF-FIN (2) (code 10098).
Area of use: Finland - onshore.
