The present invention provides technologies for mapping the locations of federated devices, such as their physical locations. Individuals carrying mobile devices on their person may make use of such devices to determine their relative physical location or the relative physical location of others carrying such devices, such as family or friends. Such devices may send out relative and/or absolute location information to other devices in a federation or the like, such information being used to create a map of relative and/or absolute locations of the devices. Typically, the more devices that send out location information, the more accurate the location mapping. If one or more of the devices is able to provide absolute location information, such as longitude, latitude, altitude, or the like, then the mapping may include absolute locations of at least some of the devices accurate to some degree.
