Set up your own routing web application using OpenStreetMap data and open source software

Did I mention that I love OpenStreetMap? It’s not just the map that looks more beautiful and complete every day, but also all the neat things it allows people to do with the raw data which is free for anyone to pick up and use. This is not usually something I engage in myself – suum quique – but it does feel good to get your hands dirty with some open data and open source software once in a while.
