Global Photo Database

The Global Photo Database (GPDB) would really work if camera makers started building GPS receivers into cameras, but it can be done now if people enter the metadata.

The idea is something like Expedia or Mappoint or Google Maps. The difference is that the world's pictures are indexed to the map at the time/date they were taken. Lets say you took some pictures at Niagara Falls on a certain day/time. You upload your photos to the GPDB, the metadata is collected and indexed and added to the database of photographs.

Now on the web you can look up a map of Niagara Falls then select the day/time you were there, and little triangular icons show where photos were taken. You could easily find other pictures of yourself if any were taken from different angles, and so could other people who happened to be there at the same time/date.

Photos that were not taken at the exact moment are shown, but are of increasing transparency the farther in the future or the past that they are. Click on the picture icon (a small wedge indicating the picture angle perhaps), and you see the picture that was taken.

A slider (or some other control) allows you to expand the time range, so that picture icons are visible from a just a minute, to over a great range of time.

You could go over all the trips in your life and see if anyone took any pictures of you or of the places you were in that are better than the ones you took.
