- Q4336080 abstract "In the British Isles, an ordnance datum or OD is a vertical datum used by an ordnance survey as the basis for deriving altitudes on maps. A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. In particular: In Great Britain, OD for the Ordnance Survey is ODN (Ordnance Datum Newlyn), defined as the MSL at Newlyn in Cornwall between 1915 and 1921. Prior to 1921, OD was taken from the level of the Victoria Dock, Liverpool (ODL).
