About a year ago, Apple announced a huge change to Apple Maps. It wasn’t about new features in the Maps app (though there are new features coming in iOS 13), but rather a complete overhaul of the fundamental map data. Buildings, rivers, roads, vegetation; it’s all vastly more detailed and accurate in the new maps.
Apple began rolling out the new mapping data to Northern California just after its announcement, with a promise to continue rolling out new maps to the rest of the U.S. “over the next year.” Southern California and Hawaii followed in late 2018, then parts of the southwest in April 2019.
