Ordnance survey maps are maps that show altitude in relation to a 'known' ordnance datum. An ordnance datum is a point of particular altitude. In the UK, that ordnance datum for ordnance survey maps is the mean sea level at Newlyn in Cornwall. Ordnance survey maps typically show topography, by means of contour lines and spot heights. General land detail, such as grass-land, forest, marsh. In addition roadways, railways, footpaths and bridleways are shown. This makes ordnance survey maps of particular use for anyone wishing to navigate on foot. And this remains one of the most popular uses for this type of map.
