Political Boundaries are available here - "The County, ED’s and Townlands are digitised from OSi large scale data at 1:1,000, 1:2,500 and 1:5,000 scale and are available on a county or national basis (Republic Only) in DXF, SHP and TAB formats. All boundaries are available in both Irish National Grid (IG) and Irish Transverse Mercator (ITM) projections.

Small Areas are a national boundary dataset, which subdivides the existing Electoral Districts (ED) boundaries into substantially smaller units, with each small area having a minimum of 65 households."

The OSI is governed by the ORDNANCE SURVEY IRELAND ACT, 2001, which means that it is the states NMO but also a commercial enterprise.

There is an interactive map Viewer,588882,739883,0,10 that allows the public to visualize the data.

Data are available via webmapping service called MapGenie with additional information provided here Data are accessed this way via an institutional agreements between clients and OSI. MapGenie is not open to the public on a free basis.

The data are machine readable as just explained but for a fee and the same is true for data available in bulk.

Reviewer comments

This is still under review. I have a note out to the OSi re-roads and water features. The OSi may be the distributor but they may not be the data owners. SOme data are also available on GeoDirectory.
