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…
EVRF2000 (archived) The EVRS is realized by a certain adjustment of the United European Leveling Network (UELN). The data handling and adjustment are carried out at the UELN data and computing centre at the Bundesamt für Kartographie und Geodäsie (BKG) in Leipzig.…
Height Datum Relations The vertical datum of a height reference system is usually determined by the mean sea level, which is estimated by one or more tide gauges of an adjacent sea. The tide gauge stations of the national height systems in Europe are located at…
Results and products Some projects were initiated to establish the European Vertical Reference System. In the respective sub-topic these projects are described in detail: Height Datum Relations between national height systems and the European Vertical Reference…
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…
