Remarks

In 2024 the horizontal component of this compound CRS, EWR2 Grid (ETRS89 / EWR2 SnakeGrid), was extended eastwards as the EWR3 Grid (ETRS89 / EWR3 SnakeGrid) (CRS code 10851). To the west of Bedford the EWR2 Grid is an exact subset of the EWR3 Grid; over this extent EWR3 Grid + ODN height (CRS code 10852) replaces EWR2 Grid + ODN height.
