EUREF Working Group "European Unified Height Reference" The working group was established at the EUREF Symposium 2021 by resolution 2021/1. Its goals comprise to complement EVRS with an official height reference surface (hybrid quasigeoid model), to improve…
Activities EUREF Working Group "European Unified Height Reference" The WG was established in 2021 to provide improved information about national realizations of the integrated geodetic reference and to establish a unified European height reference surface for…
National reference frames and geoid models It is a well-known fact that the national height systems in Europe refer to different datums and standards and therefore differ at the decimeter or meter level (see the example in the Figure below or Height datum…
Realization of EVRS Over the years, three realizations of the EVRS have been published. The current version is EVRF2019. The national height systems of some countries as well as previous activities such as EUVN / EUVN-DA are based on the older realizations EVRF2000…
