EUREF

• is the key organization for the support of theis the key organization for the support of the geodetic GNSS ground based infra-structure in Europe- GNSS, Height and Gravity reference frames –

• established a working group to for definition and realization of continental geodetic reference system

• takes over geodetic tasks of EuroGeographics – the European legal entity of more than 50 European NMCA’s i th 40 t tin more than 40 states

• supports the IAG (IGS, GGOS, …) items in EUROPE and ill t i l b i t t t i thwill certainly be an important partner in the

implementation of INSPIRE (EC), GGOS (IAG), GEOSS (GEO)
