Here’s an experimental Google map made using some excellent software from UCL Centre for Advanced Spacial Analaysis (Casa). The application slices up a large digital image – the one used here is 8000 x 8000px 30mb into a 256 x 256 pixel tiles (you might have noticed the how the map image builds up from these unit blocks).

The tiles correspond to the magnification of the map. At the lowest level the entire image is contained within a single 256 pixel square repeated left and right – this is the maps initial state. As you zoom in the tile samples are closer to the original image resolution.

The plan for the map is to lay a data layer on top of the map corresponding to each individual badge. This will hook up to the eBay API so when it comes time to sell the badges we can see a live data feed.
