Apple is ready for Apple Maps to stop being a joke. The company plans to introduce completely overhauled mapping data in the US over the next year, all using information that Apple gathered itself, according to TechCrunch, which got a behind-the-scenes look at the new pursuit.

The new data will begin to roll out in the coming weeks in a very limited fashion. It’ll start first for people enrolled in the iOS 12 beta, and the updated mapping data will only be available for San Francisco and the Bay Area. The report says it’ll grow to cover all of Northern California by fall and eventually come to all versions of iOS.
