Geodetic CRS: ED50
Datum: European Datum 1950
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: EPSG
Information source: OGP
Revision date: 2007-03-27
Scope: Transformation of coordinates at 1m level of accuracy.
Remarks: Parameter values from ED50 to ETRS89 (11) (code 15895). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. NOTE: Parameter file is non-conformant with NTv2 specification - replaced by ED50 to WGS 84 (41).
Method: NTv2
Area of use: Spain - mainland, Balearic Islands, Ceuta and Melila - onshore.
