Geodetic CRS: ED50
Datum: European Datum 1950
Ellipsoid: International 1924
Prime meridian: Greenwich
Data source: OGP
Information source: Rijkswaterstaat report 9635 "Coordinaattransformaties en kaartprojecties", September 1996.
Revision date: 2009-05-15
Scope: E&P operations in the Dutch sector of the North Sea.
Remarks: Parameter values from ED87 to WGS 84 (32) (tfm code 3905), assuming that ED87 is identical to ED50. Errors caused by this assumption can reach 3-5m. Used by NAM for offshore operations until mid 2004, then replaced by tfm code 1311.
Method: Position Vector transformation (geog2D domain)
Area of use: Netherlands - offshore North Sea.
