Device positioning via device-sensed data evaluation

The subject disclosure is directed towards a technology by which data sensed at a device (102) may be used to determine the likely location of the device, independent of whether GPS data is also available. In one aspect, information representing the sensed device data is sent to a remote service (132), where it is compared with similar information for known locations to find a matching location. In another aspect, the information is locally processed against locally cached information to find a matching location.
