A personal location system including signal-transmitting RFID tags associated with various landmarks, such as hallways of buildings. The system's personal receiver is preloaded with information about the building, equivalent to a map, and receives the RFID signals. These signals, in conjunction with the stored map, allow the environment to be displayed, and the location of the user to be identified. The receiver may be loaded with the map information by means of a device(s) located at the entrance(s) of the building.
