A few weeks ago we released our shapefiles via the API, and while most people were excited, some folks were a bit confused about what it all meant. Which is why Tom Taylor’s beautiful Boundaries application is so exciting. It helps you visualize the Flickr community’s twisty changing complex understanding of place.

You throw in a place name and it’ll attempt to find that place’s neighbours, using Yahoo GeoPlanet. For each of those neighbours, it uses the WOE ID to fetch and render the polygon from shapefile that Flickr returns. – Tom Taylor: Flickr boundaries, now free to play with
