Apple is quietly working on a new indoor mapping system
Apple has discreetly released an RF-based interior positioning app called Indoor Survey, as spotted by developer Steve Troughton-Smith. It appeared recently on the App Store, and the description says you can "drop 'points' on a map within the Survey App [to] indicate your position within the venue as you walk through. As you do so, the Indoor Survey App measures the radio frequency (RF) signal data and combines it with an iPhone's sensor data." That lets you find your position inside a mall, arena or other venue "without the need to install special hardware," according to Apple.
