Abstract

Methods and systems for updating altitude information for a location by using terrain model information to prime altitude sensors are disclosed and may include determining an altitude of a wireless device including one or more altimeters. The determination of altitude may include determining a location of the wireless device, receiving an altitude value for the location from an altitude database, and measuring a change in the altitude using the altimeters. The database may include a worldwide terrain database that may be stored on a remote device, such as a server. Part of the database may be stored on the wireless device and may be updated as the wireless device moves. The location may be determined utilizing a global navigation satellite system, which may include GPS, GLONASS, and GALILLEO. The location may be measured utilizing cellular service triangulation or by utilizing one or more access points with known locations.
