What does ordnance survey map mean?

Answer 1

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.

Answer 2

An Ordnance Survey WAS an exact survey of an area for Ordnance (Artillery).

A castle would survey the area in front of it, and often Mark the limits of their artillery with large stone pillars. An armed soldier walking past those pillars would be inside the range of their artillery. Since there are different artillery, there would be a set of stone pillars, and as you walked past each, you became vulnerable to THAT artillery piece.

This methodical marking off of range, turned out to teach cartographers how to make maps more accurate, as they actually started marking out accurate distances to each map feature, the maps got steadily more accurate.

The term is almost more a map making and charting feature term, than the original military one.

Answer 3

it means ......

The Ordnance Survey National Grid reference system is a system of geographic grid references used in Great Britain, different from using latitude and longitude.

You would use an ordnance survey like you would use any map. It also has the necessary information a person would need to fire artillery pieces over long distances using range and bearing calculations.

Answer 5

They map all of Great Britain, creating both paper and digital maps that are used by consumer, businesses and government for leisure activities, planning construction and engineering works, predicting flooding and much more.

While most people think of the paper maps initially, most of their income comes from licencing data to businesses, local and central government.

Answer 6

so they can see the most likely routes (e.g. public foot paths) to avoid contact

Answer 7
