GeoClue provides a system service that applications can use to become geo-aware and make reading and writing geographical information as simple as time or date by allowing easy access to location data from sources like GPS, GSM, WiFi and IP addresses. It aims to solve the problem of accessing location data being too difficult by providing a standard interface for applications to query for the user's location and for location providers to publish location updates. The document provides information on the GeoClue architecture and examples of how geographical data could be used in applications and messages.
