Abstract
A method and system of updating a crowd-sourced data repository. The method is executed in a processor of a server computing device 108 and comprises storing a fingerprint map of an indoor facility in the crowd-sourced data repository, the fingerprint map having positioning fingerprint data that includes barometric fingerprint data, receiving, at the crowd-sourced data repository, at least one of mobile device signal data and mobile device sensor data correlated with a sequence of positions describing a movement of a mobile device along a trajectory relative to the indoor facility, the sensor data including mobile device barometric pressure measurements for at least a pair of contiguous positions in the sequence of positions. Then, based on identifying a pattern match between the mobile device barometric pressure measurements and the barometric fingerprint data over the at least a pair of contiguous positions, automatically updating, using the processor, the crowd-sourced data repository by adding the mobile device barometric pressure measurements to the barometric fingerprint data of the crowd-sourced data repository.
