EUREF, the IAG (International Association of Geodesy) Reference Frame Sub-commission for Europe, deals with the definition, realization and maintenance of the European Reference Frame. EUREF works in close cooperation with the pertinent IAG components and EuroGeographics, the consortium of the NMCA (National Mapping and Cadastre Agencies) in Europe. This paper presents an overview of EUREF and describes its missions, activities and the recent developments, aiming at upgrading European-wide geodetic reference systems to support both scientific and continental geo-referencing activities.@en
