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. It was implemented jointly by the Ordnance Survey Ireland (OSi) and the Ordnance Survey of Northern Ireland (OSNI) in 2001.
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]

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 The one-inch maps continued to be produced until the 1970s, when they were superseded by the 1:50000-scale series – as proposed by William Roy more than two centuries earlier.
Geograph Britain and Ireland is a web-based project, begun in March 2005, to create a freely accessible archive of geographically located photographs of Great Britain and Ireland. [1] 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 ...
