OSI Maps

Ordnance Survey Ireland Discovery Series Maps

OSI arose from the original Ordnance Survey of Ireland, which was founded in 1824 as part of the British army. OSI was established to survey the entire island of Ireland as part of land valuations for taxation purposes. OSI now produces some of Ireland's most detailed maps to date.
