EUREF

EUREF is a network of European geodetic reference points. It was established to provide a unified and consistent geodetic reference system for Europe, ensuring accurate and reliable spatial data across the continent. The primary goal of EUREF is to maintain and disseminate the European Terrestrial Reference System (ETRS89) and the European Vertical Reference System (EVRS). ETRS89 is a geocentric, time-dependent coordinate system that is fixed to the stable part of the Eurasian tectonic plate. EVRS is a vertical reference system based on a common height datum.

The EUREF network consists of a dense distribution of permanent GNSS (Global Navigation Satellite System) stations, precisely measured leveling lines, and other geodetic control points. These stations are continuously monitored, and their data is used to define and maintain the ETRS89 and EVRS. This ensures that coordinates derived from different national geodetic networks are consistent and can be seamlessly integrated.

The establishment and maintenance of EUREF have significant implications for various applications, including geographic information systems (GIS), land surveying, navigation, environmental monitoring, and scientific research. By providing a common spatial reference framework, EUREF facilitates cross-border cooperation, enhances data interoperability, and supports the development of pan-European spatial data infrastructures. The EUREF Technical Secretariat, based in Brussels, Belgium, plays a central role in coordinating the activities of the network and disseminating its products.
