Abstract
A method and system of localizing a mobile device having a processor and a memory. The method comprises monitoring, using the processor and the memory, mobile device barometric data along a sequence of positions describing a route being traversed, accessing, using the processor, a repository of barometric fingerprint data associated with respective positions along the route, and using the processor, localizing the mobile device based at least in part on matching a mobile device barometric pattern segment with a correlating pattern segment of the barometric fingerprint data of the repository, the mobile device barometric pattern segment derived at least partly based on ambient barometric pressure measurements associated with at least a pair of contiguous positions in the sequence of positions describing the route.
