European terrestrial reference system 89 (ETRS89)

recommended terrestrial reference system for Europe and coincident with ITRS at the epoch 1989
NOTE: Unlike ITRS, ETRS is centred on the stable part of the European plate and not subject to change due to continental drift in most of Europe.

identifier” is preferred to better align with the activities of ISO/TC 211.
