What is ITM grid reference?
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.
What is ITM projection?
ITM is the Irish Transverse Mercator Coordinate System, based on a Transverse Mercator projection and optimised for the entire isle of Ireland, jointly created by the Ordnance Survey of Ireland and the Ordnance Survey of Northern Ireland (OSI & OSNI).
What is a UTM grid?
UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width.
What is the difference between UTM and WGS84?
The difference is that WGS 84 is a geographic coordinate system, and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees).
Is grid an Irish reference?
The Irish grid reference system is a system of geographic grid references used for paper mapping in Ireland (both Northern Ireland and the Republic of Ireland). The Irish grid partially overlaps the British grid, and uses a similar co-ordinate system but with a meridian more suited to its westerly location.
What are ITM maps?
1.1 What is ITM ITM is a newly derived GPS compatible mapping projection that is associated with the ETRS89 and the GRS80 ellipsoid. It takes advantage of the accuracy of GPS whilst minimising mapping distortions.
What UTM zone is Ireland?
UTM Zone 29
Ireland is situated in UTM Zone 29, which has a central meridian 9° West of Greenwich, resulting in a small part of Counties Antrim and Down in the east of Northern Ireland extending outside the nominal zone width boundary of 6° West of Greenwich.
