Every day, Google’s Street View cars capture massive amounts of data and the company then publishes them on Google Maps at regular intervals. Until now, the only images you could see on Google Maps were the latest images. Starting Wednesday, however, you will also be able to go back in time and see older images. When you’re in the Street View interface, you will now see a small clock icon on the page. Once you click that, a preview image with a timeline underneath it will appear and allow you to see the older images. It looks like Google’s Street View cars pass by most locations about twice per year. There is a bit of variation here, however, and some urban areas especially have more historical images available while some rural areas may have fewer. In many regions of the world, Google only started collecting this imagery in the last few years (it launched in the U.S. in 2007), so that may also limit the availability of historical images.
