1. A method for deploying a calibrated positioning map of an area, the method executed in a processor of a server computing device and comprising: 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 at least one of a predetermined and a dynamically updated threshold density of calibration data points, deploying the updated distribution as the calibrated positioning map of the area.
