A method provides real-time location tracking with the feature of map-in-map for multiple people. According to this method, when a person is tracked by another person on the map shown on another person's mobile device, the tracked person sends his or her location information to a server. The server will save a copy of it to a mailbox of another person and send this information to another person whenever he or she is available, i.e., his tracking application is running on mobile device's foreground. The information will be used to mark the tracked person's location on the map. On a single map, multiple persons can be tracked. And the annotation of each person is clickable and then a small sub-map pops up to show a local map having just that person and track that person's moving, so as to offer a map-in-map function. |
