• Ordnance Survey Ireland Historic Maps
  Between 1829 and 1842 Ordnance Survey Ireland completed the first ever large-scale survey of an entire country. Acclaimed for their accuracy, these maps are regarded by cartographers as amongst the finest ever produced. As the national mapping archive service of Ireland, OSI has captured this and later mapping data in a digitised format. Ordnance Survey Ireland website also includes access to the important 25” series indexed by parish which was completed in 1913. These maps are particularly relevant for genealogy or for those with an interest in social history.

• Open Street Map
  Open Street Map is a free, editable map of the whole world that is being built by volunteers largely from scratch and released with an open-content license. The Open Street Map License allows access to map images and underlying map data.
