spot height
A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum.〔Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, p. 506. ISBN 0-14-051094-X. 〕 In the UK this is the Ordnance Datum. Unlike a bench-mark, which is marked by a disc or plate, there is no official indication of a spot height on the ground although, in open country, spot heights may sometimes be marked by cairns. == See also ==
