The Geotaggers’ World Atlas is my long-term project to discover the world’s most interesting places and the routes that people follow between them. Five years ago I first started retrieving photo locations from the Flickr search API and drawing lines between them to make the first version of the Atlas.

Today I’m able to launch the full Geotaggers’ World Atlas covering every city in the world. Thanks to Flickr’s API, it exposes over 10 years of photo locations, and as a web map it lets you explore not just the largest centers of activity but also their context, anywhere on earth.

As an exercise in coding, this is interesting. As a visualization of data, it’s utterly fascinating. The only downside is the interactive map doesn’t have details like street names so it may be hard to find out what is so fascinating about that particular location but look up your own city on the map and see if you can spot “the most interesting places”.
