Nathan Lambert has extended the work that Possum has done in mapping election results by booth. He has produced excellent Google Earth maps showing vote levels, which you can access here. I’ll probably spend all day playing with them.
Update: Lambert’s go great with my Google Earth maps showing electoral boundaries. You can download them from my maps page, and you can overlay the boundaries and the booths.
Thanks for sharing these maps. They’re fantastic and quite detailed for the areas covered. Plus they provide an awesome way of visualising voter groupings.
