Apple in December began testing an expansion of its more detailed Apple Maps app in the Central and Southeastern parts of the United States, along with Alaska, and that updated Maps content is now rolling out to all customers.

The revamped Maps app features more extensive geographical details, with updated buildings, roads, parks, sports fields, parking lots, foliage, pools, pedestrian pathways, and bodies of water.

To get its mapping data, Apple uses its own vehicles equipped with LIDAR sensors and cameras. Apple has been using this method to collect mapping information for years now.

Apple began rolling out its updated mapping app to customers starting in iOS 12, and at the 2019 Worldwide Developer Conference, Apple said all customers in the United States would receive the improved Maps app by the end of the year.

Apple has made good on that promise with the rollout of the new mapping terrain to large swathes of the United States, and the updated Maps are now becoming available across most of the country. It could still take some time for all users in the Central and Southeastern areas of the U.S. to see the new content. Apple plans to bring the new Maps app to additional countries in 2020.

Update: Though Apple has begun releasing the new mapping updates across the United States, updated Maps features are not yet showing up for all users in the Southeast at this time.

Update 2 — Jan 30, 2020: The rollout of revamped ‌Apple Maps‌ in the Southeast and Central United States now appears to be complete. This includes the addition of traffic lights and stop signs in ‌Apple Maps‌ on CarPlay.
