My friend asked me recently: "Can I get global coordinates printed on the picture I take with my phone." I said "I dunno ... but I could quickly build an app for you."
Now the idea borne out of that convo was to create something like a global repository -- graph of pictures, connected together by coordinates of where they were taken.
One cool use I thought was to see/explore photos of areas I would like to visit (like fiji or amsterdam for e.g.).
I am interested in ... * whether anyone thinks this is a good idea, useful and fun? * other cool uses for this * or, if it already exists in some form -- I assume there are photo sharing apps with these capabilities but in the extrapolated form I presented?
