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.
[2] [3] There are 332,216 such grid squares containing at least some land or permanent structure (at low tide), of which 281,131 have Geographs. [4] Geographs are being collected for all parts of Great Britain, Isle of Man and Ireland. The Channel Islands fall outside Britain's grid system, but may be geographed using their local UTM grid.
Up to 1879 the 1:2500 maps were accompanied by Books of Reference or "area books" that gave acreages and land-use information for land-parcel numbers. After 1879, land-use information was dropped from these area books; after the mid-1880s, the books themselves were dropped and acreages were printed instead on the maps. [ 2 ]
The metric national grid reference system was launched and a 1:25000-scale series of maps was introduced. The one-inch maps continued to be produced until the 1970s, when they were superseded by the 1:50000-scale series – as proposed by William Roy more than two centuries earlier.
English: Map of the National Grid in Great Britain, featuring all transmission lines and substations at 220 kV and above. Derived from OpenStreetMap data in February 2023, which is, as far as I am aware, an accurate representation of the current grid.
A typical map with grid lines. The Ordnance Survey National Grid (United Kingdom) and other national grid systems use similar approaches. In Ordnance Survey maps, each Easting and Northing grid line is given a two-digit code, based on the British national grid reference system with an origin point just off the southwest coast of the United ...

Map of centres of UK and England by various methods Put simply, the centroid is the point at which a cardboard cut-out of the area could be perfectly balanced on the tip of a pencil. [ 4 ] Islands are assumed fixed to the mainland in their precise position by invisible rigid weightless wires.
