Abstract
A method and system for deploying a calibrated positioning map of an area. The method, executed in a processor of a server computing device, comprises receiving, at a memory of the server computing device, a first set of fingerprint data acquired within the area by a plurality of mobile devices, generating, using the processor, a distribution of calibrated data points based at least in part on the first set of fingerprint data, the calibrated data points representing respective positions within the area, receiving, at the memory, a second set of fingerprint data acquired by at least one additional mobile device, processing, using the processor, the second set of fingerprint data and the calibrated data points to generate an updated distribution of calibrated data points, and when the updated distribution exceeds a predetermined threshold density of calibration data points, deploying the updated distribution as the calibrated positioning map of the area.
