Mapping Geotagged Photos in Public Spaces

For any city, thousands of geotagged photos are available online. This  project by Philipp Schmitt maps these photos in the places where they were taken.

A custom-built camera flash + smartphone setup queries the Flickr and Panoramio APIs for photos taken at the current geographical position. Whenever there’s a photo available, a flash is triggered. Long-exposure photography captures multiple flash lights — each representing one geotagged photo — and situates them in the place of their origin.
