Yahoo! Research Berkeley has released Tag Maps. Tag Maps aims to add a psycho-geographic overlay to any location. By aggregating geo-located Flickr tags, Tag Maps visually shows what people think (or have tagged ) any given area. Pretty cool. Unlike the Lamp/Lamp project mentioned earlier last week, Tag Maps has a public API which makes it even cooler. More information can be found on the Yahoo! Research Berkeley web site.
