This was a snippet of my presentation at Sydney GeoRabble explaining what my team did at the 2012 GovHack event. It is only two slides, but covers some of the GIS trickery we needed to do as part of the analysis for the event. Slides are with limited context, unfortunately, as I presented most of the information.
