Regional Reference Frame Sub-Commission for Europe

Regional Reference Frame Sub-Commission for Europe (EUREF) is the sub-commission of the IAG (International Association of Geodesy) that deals with the definition, realization and maintenance of the European Geodetic Reference Frame. The goal of EUREF is to establish a unified geodetic datum for Europe (ETRS89) and a consistent network of reference stations (EPN) throughout Europe. EUREF was founded in 1987 at the IUGG General Assembly held in Vancouver.
