An OD (Ordnance Survey) map are maps that were originally used for the military.
It was produced by following a series of surveys.
Hope this helps.

The name dates back to World War II. Much of the mapping carried out during the war was done by the Department of Ordnance (the guys who take care of munitions, artillery, tanks etc.). Their maps then, were known as Ordnance Survey maps. Today, Ordnance Survey maps are carried out by civilian teams and have nothing to do with ordnance but the name has stuck.

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.

On a UK Ordnance Survey map, a main 'A' road (trunk road, etc) is often shown in red.
Red . On all the many OS maps that I have, motorways are blue.
