Anyone coming to my blog looking for Dail constituencies, I don't have em.
The official Constituency Commission has images and detailed reports on the boundaries and changes.
Go here for the 2012 boundaries in google-kml http://www.tallyroom.com.au/maps (freeif credited to Ben Raue ) or here for more detailed ones with Electoral (sub) Divisions http://icampaigned.com/blog/dail-constituency-maps/ (not free) or go Ordnance Survey Ireland for commercial use files.
Of course I think digital boundaries files of useful detail should be information should be free for non-commercial reuse.
A lot of outer Dublin wasn't very clear in GE but they updated some areas like the Dublin mountains so I can trace the border more accurately, but not the very northwest of county Dublin.
So I've updated them here I consider it still a draft until more eyes have been on it to spot any mistakes I may have made. I had hesitated on publicising them more because I thought maybe bad maps are worse then no maps. But along as have caveats about their accuracy people may still find them useful. At some point I saved an old map over a newer ones I had double checked which so I wasn't sure which I had double checked which browned me off on the whole thing. As new higher resolution photos of Dublin appear the lines no longer match exactly...:/ And the commission maps doesn't stretch and match over the GE satellite image either. I don't think they'll ever be perfect.
I'll add links descriptions, TD's, election result and other constituency stats.

PS. The creator of itison.tv has pointed there the OSI have new web service called Smartmaps He shows us some different views of Tara, Rath Lugh and Lismullin. There have couple of different types of maps you can buy but you can't seem to preview them. Also strangely there are earlier maps then the ones at the NPWS with maps from ~2003 that shows the scar of the M3 going through Tara, these aerial photos are very different a step clearer and brighter feel 70's.
PPS. Eirepreneur continues to jump start Irish uses of new mapping apps by giving an example of a collaborate google mymap, he has started one on wifi hotspots. I hope to find a project to create my own and get people involved. I was wondering would it be efficient to use this collaborative method to create maps for the constituencies for the rest of Ireland and the European and local elections, but I don't know whether hand traced maps data would eventually be useful for anybody to use and mash up to display other information. Any other ideas for useful Irish collaborative maps?
