In general, neither Ireland nor Great Britain uses latitude or longitude in describing internal geographic locations. 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 ...
ITM coordinates on an OSi map from 2006. In this example the easting and the northing are separated by a comma. An illustration of ITM coordinates over a map of Ireland. Eastings are on the top/bottom. Northings are on the right/left. Irish Transverse Mercator (ITM) is the geographic coordinate system for Ireland.
The exact location lies at the Irish Transverse Mercator (ITM) coordinates 633015.166477, 744493.046768, and at Latitude: 53.4494762 and Longitude : -7.5029786. [1] It sits in the townland of Adamstown within a National Monuments Zone, on the location of an ancient graveyard and near the remains of Kilbride church.
Given that every projection gives deformations, each country's needs are different in order to reduce these distortions. These national projections, or national Coordinate Reference Systems are officially announced by the relevant national agencies. The list below is a collection of available official national projected Coordinate Reference ...
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.
This implementation is of great importance since it is widely used in the U.S. State Plane Coordinate System, [5] in national (Great Britain, [6] Ireland [7] and many others) and also international [8] mapping systems, including the Universal Transverse Mercator coordinate system (UTM).
Photographs in the Geograph collection are chosen to illustrate significant or typical features of each 1 km × 1 km (100 ha) grid square in the Ordnance Survey National Grid (of Great Britain and Northern Ireland) and the Irish national grid reference system. [3] There are 331,920 such grid squares containing at least some land (at low tide). [4]
EirGrid's primary purposes are the daily management of the Irish national grid, the operation of the wholesale power market, and the development of high voltage infrastructure to serve Ireland's economy. The Irish National Grid is a 3-phase wide area synchronous grid that is not synchronised with the GB's National Grid. The high voltage ...
