Geodetic CRS: ED50
Datum: European Datum 1950
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: Geodesy Unit, Cartographic Institute of Catalonia (ICC); http://www.icc.cat
Revision date: 2012-03-24
Scope: Transformation of coordinates at 0.05m level of accuracy.
Remarks: ICC publishes as two tfms, code 100800400 for ED50 to ETRS89 and code 800100400 for reverse when ordinate 1 = 129.547m, ordinate 2 = 208.186m, dS = 0.9999984496 and rotation = -1.56504". See ED50 to ETRS89 (14) (code 5661) for emulation using NTv2.
Method: Similarity transformation
Area of use: Spain - Catalonia onshore.
