This data category requires a high level national map. To satisfy this category, the following minimum criteria must be met:
- Scale of 1:250,000 (1 cm = 2.5km).
- Markings of national roads
- National borders
- Marking of streams, rivers, lakes, mountains.
- Updated at least once a year.
Political Boundaries are available here - http://www.osi.ie/products/professional-mapping/boundary-data/ "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 http://www.irishstatutebook.ie/2001/en/act/pub/0043/, which means that it is the states NMO but also a commercial enterprise.
There is an interactive map Viewer http://maps.osi.ie/publicviewer/#V1,588882,739883,0,10 that allows the public to visualize the data.
Data are available via webmapping service called MapGenie http://www.osi.ie/Services/MapGenie.aspx with additional information provided here http://www.osi.ie/Services/MapGenie-Learn-More.aspx. 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.
In terms of Intellectual Property OSI data are protected under the Copyright and related Act 2000 as discussed here it data are not available under an OPEN LICENCE, all OSI data are protected under the Copyright and related Act 2000 as discussed here http://www.osi.ie/Services/Copyright.aspx, and Copyright Permit CP1 and there are Licence Fees. For example "copyright Ordnance Survey Ireland and Government of Ireland and are protected under the terms of the Copyright Acts. Anyone wishing to reproduce OSi material, or use it as a basis for their own publications, must obtain prior permission from OSi. The permit covers reproduction of OSi mapping data in facsimile form and also the use of copyright material in a new compilation based on OSi mapping. The permit requires that an acknowledgement to Ordnance Survey Ireland and Government of Ireland copyright and a permit number must appear on the final reproduction".
The OSI has allowed some academic institions to display and use their data via MapGenie here is one example (http://airo.maynoothuniversity.ie/datastore/private-households-t5-sa) however this is for non commercial use only
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.
