Going Places on Flickr: The Significance of Geographical Information in PhotosEvery photo has a location—it was taken somewhere. For photo-sharing communities like Flickr, geotagging enriches the database with location metadata and makes digital photos more useful and relevant to users, allowing them to not only easily search and organize their own photos but better browse images from around the world. With nearly 50 million geotagged photos on Flickr, around 32 million of which are public, Flickr senior engineer Dan Catt was able to use Flickr’s open API to create a new feature called Places. Places is a zoomed-in view of a particular location and allows Flickr members and visitors to explore that location through iconic photos.

Since 2004, the Where 2.0 Conference has been the place where the grassroots and leading edge developers building location aware technology intersect with the businesses and entrepreneurs seeking out location apps, platforms, and hardware to gain a competitive edge. In the O'Reilly conference tradition, Where 2.0 presents leading trends rather than chasing them.
