The Ordnance Survey National Grid reference system (OSGB), also known as British National Grid (BNG), [1] [2] is a system of geographic grid references, distinct from latitude and longitude, whereby any location in Great Britain can be described in terms of its distance from the origin (0, 0), which lies to the west of the Isles of Scilly.
England prints its own banknotes which are also circulated in Wales. The economy of England is the largest part of the United Kingdom's economy. Regional differences: A map of England divided by the average GVA per capita in 2007 showing the distribution of wealth. The strength of the English economy varies from region to region.
Module:Location map/data/United Kingdom is a location map definition used to overlay markers and labels on an equirectangular projection map of the United Kingdom. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Indicate the cardinal directions, especially on map projections in which these directions vary across the map (e.g. conic, pseudocylindrical, azimuthal) where a north arrow or compass rose would not be appropriate [5] These are usually secondary to the main purpose of the map, so graticules are often drawn to be relatively low in the visual ...
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
The distance between two points 1 degree apart on the same circle of latitude, measured along that circle of latitude, is slightly more than the shortest distance between those points (unless on the equator, where these are equal); the difference is less than 0.6 m (2 ft).
The difference between the direction of a plumb line or vertical, and a line perpendicular to the surface of the ellipsoid of revolution – a normal to said ellipsoid – at a particular observatory, is the deflection of the vertical.

The grid lines point to a Grid North, varying slightly from True North. This variation is zero on the central meridian (north-south line) of the map, which is at two degrees west of the Prime Meridian, and greatest at the map edges. The difference between grid north and true north is very small and can be ignored for most navigation purposes.
