Apple has been deploying the enhanced maps up the northeast United States over the last few months, with the rollout recently extending to New York state . Now it has expanded west to cover West Virginia, Ohio, Michigan, Indiana and North Illinois.

You can spot the updated regions by looking for more landscape details like sports fields, parking lots, ground cover, foliage, pools, pedestrian pathways and the like.

The data is gathered by Apple's own fleet of sensor- and camera-equipped vehicles, as well as first-party data gathered from iPhones using Apple's differential privacy. The combined data is also being made to ensure search results are more relevant.



The improvements initially rolled out in Northern California in July 2018, followed by Hawaii and Southern California in November 2018, and Arizona, New Mexico, and the Las Vegas metropolitan area in April 2019.

At WWDC 2019, Apple said the updated maps will roll out to the entire United States by the end of the year, followed by additional countries in 2020.
