Mapping the Streets of Ireland With R and ggplot2

Earlier today an interesting article about plotting the streets of france appeared in my feed. What Simon does in his blog post is essentially read OSM street-lines-data for France and displays it in what I find to be a rather traditional and elegant way.

The first thing I immediately though of was: "I'd love to see this for Ireland". As an OSX user, it took a few tricks to get the article replicated for Ireland therefore I've decided to share my notes.

Should you wish to replicate this for your country, here are some notes I've taken.

Get The Data
