European Terrestrial Reference System 1989The European Terrestrial Reference System 1989, usually referred to as ETRS89, is a mapping coordinate system used as the standard high accuracy system for GPS in Europe. It coincided with the World Geodetic System 1984 in 1989, hence the name, and is based on the same GRS80 ellipsoid. Unlike WGS84 or ITRS it is centred on Europe and diverges from them with the movements of the tectonic plates associated with this landmass.
