driving, public transportation, walking, or biking. Google has partnered globally with over 800 public transportation providers to adopt GTFS (General Transit Feed Specification), making the data available to third parties. The app can indicate users' transit route, thanks to an October 2019 update. The incognito mode, eyes-free walking navigation features were released earlier. A July 2020 update provided bike share routes. Traffic conditions In 2007, Google began offering traffic data as a colored overlay on top of roads and motorways to represent the speed of vehicles on particular roads. Crowdsourcing is used to obtain the GPS-determined locations of a large number of cellphone users, from which live traffic maps are produced. Google has stated that the speed and location information it collects to calculate traffic conditions is anonymous. Options available in each phone's settings allow users not to share information about their location with Google Maps. Google stated, "Once you disable or opt out of My Location, Maps will not continue to send radio information back to Google servers to determine your handset's approximate location". Street View On May 25, 2007, Google released Google Street View, a feature of Google Maps providing 360° panoramic street-level views of various locations. On the date of release, the feature only included five cities in the U.S. It has since expanded to thousands of locations around the world. In July 2009, Google began mapping college campuses and surrounding paths and trails. Street View garnered much controversy after its release because of privacy concerns about the uncensored nature of the panoramic photographs, although the views are only taken on public streets. Since then, Google has blurred faces and license plates through automated facial recognition. In late 2014, Google launched Google Underwater Street View, including of the Australian Great Barrier Reef in 3D. The images are taken by special cameras which turn 360 degrees and take shots every 3 seconds. In 2017, in both Google Maps and Google Earth, Street View navigation of the International Space Station interior spaces became available. Immersive View It was announced at the Google I/O 2022 event that 3D images would be created using Street View. It was to be initially in five cities worldwide, with plans to add it to other cities later on. Immersive View was to be available initially in the following locations: Landmark Icons Google added icons of city attractions like on Apple Maps on October 3,
