Abstract: A location service and method provides a location aware computing device that is extensible by allowing different types of location awareness providers operate with the service. The method includes receiving a request for a location context, acquiring data associated with a current location from one or more location detection devices, reconciling the acquired data for any inconsistencies concerning the current location by applying either or both of a hierarchical and a metric process, and generating a location object accessible to applications. The service includes a location management component configured to route location data, a fuser engine configured to receive one or more location reports generated from the location data, reconcile conflicts between the location reports and generate a location object, and one or more location application programming interfaces (APIs) coupled to the location management component to transmit the location object from the fuser engine to an application.
