If you are in a rush and have only 2 days (or if you are feeling adventurous and have lots of time) to spare, which landmarks can you visit? This application helps answer that question.
That is, it automatically builds an itinerary of travel photos for a given city.
Users typically click more than a couple of pictures when they visit a landmark.
Usually when they arrive at the landmark, sometime later and maybe when they leave.
The duration of a visit to a particular landmark is estimated as the time difference between
the photo uploader's last and first clicked pictures at the landmark.
We then aggregate the time spent at all the landmarks to build an itinerary for the user.
We used Flickr EXIF data to build the application.
