I have been looking online for maps of Dáil Constituencies and have found most of them are quite poor. The Oireachtas publish a National Map (Available here – 720k PDF ) which is of debateable quality.  To be fair the constituency profiles they publish are quite a decent analysis of basic population census data.

Following a request from Robert Cassidy I have created a couple of basic maps for the Galway East constituency. The base data is sourced from OpenStreetMap and is overlaid onto a backdrop of terrain data from the NASA SRTM project. The District Electoral Division boundary files are from the Central Statistics Office.

I did a quick statistical analysis of the total population in the Constituency to derive the classes below.
