Google Maps has been updated to allow users to access new “photo tours” within the service. The feature uses contributed photos from around the world that are stitched together to give a 3D photo scene of a popular location. Photo tours are available for more than 15,000 popular sites around the world and can be initiated through Google Maps in two ways. “First, when you search for a place, such as Trevi Fountain, the results in the left panel will indicate if there is a photo tour available: click either the thumbnail image or the link to start the tour,” Google wrote on its blog. “Alternatively, if you’re browsing the map and click on the label for a particular landmark, the info window that appears will indicate if a photo tour is available.” The tours require Google Maps with WebGL and are available now. A photo tour demonstration follows below.
