Abstract
A method and system of infrastructure re-purposed magnetic signatures for mobile device indoor navigation and positioning. The method comprises determining a common spatial region in accordance with a first spatial region partially superimposed upon an at least a second spatial region, the first and at least a second spatial regions associated with a first and an at least a second magnetic signatures respectively; and generating, based at least in part on the first and at least a second magnetic signatures, a re-purposed magnetic signature associated with the common spatial region.
