Apple is also conducting surveys with portable systems in select pedestrian areas (for example, certain streets in San Francisco that cannot be driven). We may periodically revisit and re-collect data in some of those locations in an effort to maintain a high-quality, up-to-date map. Vehicle surveys may use equipment mounted on the outside of vehicles as well as iPhones, iPads, or other devices inside of vehicles. Apple is conducting ground surveys with vehicles around the world to collect data to improve Apple Maps and to support the Look Around feature.
