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.
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 ...
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 The one-inch maps continued to be produced until the 1970s, when they were superseded by the 1:50000-scale series – as proposed by William Roy more than two centuries earlier.
NSG acts as the authoritative reference dataset for streets in England and Wales. [1] Access is restricted to local authorities and statutory undertakers (e.g. for maintenance or installing services). A public version of the data is made available at FindMyStreet.co.uk, a website by Exegesis which was commissioned by GeoPlace in 2018.
The postcode area is the largest geographical unit used and forms the initial characters of the alphanumeric UK postcode. [1] There are currently 121 geographic postcode areas in use in the UK and a further three often combined with these covering the Crown Dependencies of Guernsey, Jersey and Isle of Man.
Full "ten figure" grid reference Ireland: i888_999: Letter 'i' followed by two decimal numbers - eastings then northings in metres separated by an underscore R: Standard grid references. In each of these cases, the actual coordinates passed to the map sources page will be the centre of the square that the grid ref defines R16 R1267 R123678 ...
The centroid is a mathematically derived point that is in every sense the centre of a two dimensional area like a piece of land. If a straight line is drawn through a centroid in any direction there will be equal length of the line on either side of the centroid as measured from it to the boundary if the line is unbroken on either side.
