    Abstract: Disclosed are systems, methods and devices for application of measurements obtained from a compass or magnetometer in estimating a location of a mobile device. In specific implementations, expected signatures of local magnetic fields at locations are provided to a mobile device as positioning assistance data. In other implementations, magnetic measurements obtained by multiple mobile devices at identifiable locations in an indoor area may be combined for deriving expected signatures of local magnetic fields for use in positioning assistance data.
