TIMELAPSES ARE AWESOME, BUT THEY ARE unfortunately pretty difficult to put together, especially over long periods of time. The photographer must set the camera up and remain by it for the duration to make sure everything is going well. So it’s pretty much impossible for a single person to do a timelapse over a period of years.

Fortunately for us, Google and the University of Washington got together and built an automated program that catalogues 86 million internet photos, categorizes them by location, warps them into a single viewpoint, and sorts them by date. The result? A massive, crowdsourced timelapse of some of the world’s great landmarks over time. You can get a full explanation of the process here.
