next stop: semantic metaverse ï¿½ Mapping flickr Photos discusses Mappr - an application that overlays flickr photos on a map.
I love the concept - while surfing the net it's always struck me that things like travel descriptions, isolated pictures etc. feel disconnected. I'm a very visual person, and can often "picture" large interconnected systems, but picturing the web is hard - structural relationships are not obvious.
Mapping data found online to geographical locations is a great way of creating a visual relationship that makes the structure easier to picture. And photos are ideal for this kind of application because photos are "connected" to the geographical locations - knowing where they were taken will help us fill in our mental image of what context they belong in.
While you're at it, take a look at the rest of next stop: semantic metaverse too.
