European reference systems

In addition to the conventional national reference systems, there is a European reference system called ETRS89. The connection of national reference systems to global, terrestrial reference systems by means of geodetic measuring methods results in only a limited degree of accuracy. However, modern (local) reference systems, distinguish themselves by providing a precisely defined link to global systems, thus allowing absolute positioning within a centimetre.
