Technical information:

On the Norwegian continental shelf the European Datum 1950 (ED50) is the de facto and de jure geographic coordinate reference system for the Petroleum Industries licensing and operations. All positional data handled by the NPD is referenced this Datum. The service is also available in WGS84. This is done in the server with a position vector 7-parameter realtime transformation. The vector has been chosen for an overall minimum deviation from the Norwegian Mapping Authorities official algorithm. Observed deviations |dX|<1.8m |dY|<1.7m south of 62° N and |dX|<6.0m |dY|<2.6 north of 62° N.
