EUREF designed and established the European Geodetic Reference Systems. The European Terrestrial Reference System 89 (ETRS89) has a continent-wide significance. It is based on the International Terrestrial Reference System (ITRS), but tied to the stable part of Europe, so that the relationship between the two systems is entirely defined by a similarity transformation formula. ETRS89 unifies national reference systems for surveying, mapping, GIS and navigation in Europe. The benefit of ETRS89 is well demonstrated through its acceptance by several communities, e.g. EuroControl and the European Commission. The European Vertical Reference System (EVRS) is a kinematical height reference system. It is the basis for harmonisation of the vertical reference of spatial coordinates. The development of precise geoid models and monitoring their temporal variations using satellite-based techniques are necessary for the improvement and harmonisation of national height systems. The derivation of a European deformation model and a dense velocity field shall be the next step in order to improve cross-boundary positioning and science applications

Presentations of the session report on legal acceptance, potential usage in geo-referencing applications and benefit for practice of the outlined geodetic reference systems and their practical realisations.
