Photos from flickr.com (“almost certainly the best online photo management and sharing application in the world”) are often tagged with information that can be used to make educated guesses about their locations in the world. Mappr uses this data, which is provided by Flickr users and made available via the Flickr API, to place their images on a map.

Starting late 2004, we began collecting images from Flickr and comparing them against a U.S. Postal Service database of place names. Photos with consistent, informative tags are assigned a location and shown via Mappr. A certain amount of fuzziness is built into the project. Not every photo is tagged in such a way as to allow us to accurately determine exactly where it is. We make educated guesses, based on the information available in the tags.
Mappr was built to explore the idea of a collaborative mapped photo space, without having to wait for cameras to come with automatic GPS locators in them. The project is open to Flickr users, has mapped over a million photos, and continues to query Flickr’s collection of photos on a daily basis.
Mappr has been featured in publications such as Barron’s, The Wall Street Journal, and Peter Morville’s recent book, Ambient Findability. We first publicly described the motivations and strategies behind Mappr in a talk at CodeCon in San Francisco.
Note: As of 2007, Mappr is no longer processing images from flickr. Take a look at flickr to find images on maps.
