Apple recently expanded the indoor mapping feature first introduced in iOS 11 to new locations, including the Sydney Kingsford Smith Airport and indoor malls located in Dallas and Houston, Texas. The additions were noted on Apple's Feature Availability page for iOS 11.
At launch, indoor maps were only available in a handful of airports and malls around the world, but Apple has been steadily adding additional mall and airport maps.
Indoor maps are now available in more than 35 of the largest airports in the world, while indoor mall maps are available in a select number of cities in the United States and Europe, including Baltimore, Boston, Chicago, Dallas, Houston, London, Los Angeles, New York, Philadelphia, San Jose, San Francisco, and Washington, DC.
Apple's indoor mapping feature provides full layouts of each mall or airport location with icons for restaurants, elevators, bathrooms, shops, and other notable landmarks. Different floors are clearly marked, making it easy to navigate through unknown areas.
At airports, Maps users can see the location of gates, terminals security checkpoints, check-in desks, and baggage claim areas, which can be helpful when in a new location. As for malls, stores can be filtered by categories like clothes, beauty, food, and shoes, making it quicker to find what you're looking for.
A full list of all of the airports and mall locations where the Apple Maps indoor mapping feature can be used is available on Apple's website.
