Abstract
Embodiments of the present disclosure related to methods and systems of determining the floor and location of a device in an indoor space having multiple floors. A map importing module takes a floor map of an indoor space and processes it for further use. A calibration module creates a fingerprint map of the indoor space described by the floor map. A floor localization module searches the fingerprint map of each floor to determine the most likely location for each floor. A floor detection module determines the floor and location by comparing the most likely locations for each floor and utilizing device movement history data.
