WebIrish 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. The name is derived from the Transverse Mercator projection it uses and the fact that it is optimized for the island of Ireland.

WebUniversal Transverse Mercator (UTM) is an internationally recognised and widely available standard projection in mapping and GIS software. It was adopted in 1947 by the US Army, and used for military maps throughout the world. It divides the earth into sixty zones, between latitudes 84° North and 80° South. WebThe transverse Mercator projection, also known as the Gauss-Krüger projection, is similar to Mercator except that the cylinder touches the sphere or ellipsoid along a meridian instead of the equator. The result is a … WebThe Universal Transverse Mercator (UTM) coordinate reference system has its origin on the equator at a specific Longitude. Now the Y-values increase southwards and the X-values increase to the West. The UTM CRS is a global map projection. This means, it is generally used all over the world. grand theft auto achievements
