While most media attention about Apple Maps has centered on bridges on dry land, landmarks that don’t exists and other oddities, the digital cartographers at Cupertino, Calif. have been stuffing the app with some amazing features, like offline browsing. Unlike maps in iOS 5, Apple’s vector-based Maps are cached and GPS navigation work even without an Internet connection.

By comparison, Google Maps, which use bitmap tiles, would let you navigate offline for about a 10 mile radius before complaining.
