Abstract
Methods, program products, and systems for monitoring a location fingerprint database are described. A location fingerprint database can store location data associated with multiple signal sources. A mobile device can use signals of the signal sources and the location data to determine a current location. A location server can monitor the location fingerprint database, including detecting if any one of the signal sources has moved or otherwise becomes unsuitable for location determination. The location server can prevent location data associated with the unsuitable signal source from being used by the mobile device to determine the current location of the mobile device
