The Ordnance Survey (OS) devised the national grid reference system, and it is heavily used in its survey data, and in maps based on those surveys, whether published by the Ordnance Survey or by commercial map producers. Grid references are also commonly quoted in other publications and data sources, such as guide books and government planning ...
A reference to a definite grid square with variable, explicit precision (size), rather than to a point with (usually) unspecified precision implicit in number of decimal places. All of the above also lead to USNG references being typically very succinct and compact, with flexibility to convey precise location information in a short sequence of ...
The Ordnance Survey maps of Great Britain use the Ordnance Survey National Grid The Ordnance Survey's original maps were made by triangulation . For the second survey, in 1934, this process was used again and resulted in the building of many triangulation pillars ( trig points ): short (c. 4 feet/1.2 m high), usually square, concrete or stone ...
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 ...
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 OS MasterMap is the premier digital product of the Ordnance Survey. It was launched in November 2001. It is a database that records every fixed feature of Great Britain larger than a few meters in one continuous digital map. Every feature is given a unique TOID (TOpographical IDentifier), a simple identifier that includes no semantic ...
The Unique Property Reference Number (UPRN) is a unique number (a geocode) for every addressable location—e.g., a building, a bus stop, a post box, a feature in the landscape, or a defibrillator—in Great Britain. [1] Over 42 million locations have UPRNs, which can be found in Ordnance Survey's AddressBase databases. [1]
Instead grid reference systems are used for mapping. The national grid referencing system was devised by the Ordnance Survey, and is heavily used in their survey data, and in maps (whether published by the Ordnance Survey of Ireland, the Ordnance Survey of Northern Ireland or commercial map producers) based on those surveys. Additionally grid ...
