<p>A location tagged data provision and display system. A personal communication device, or PCD (20), with electromagnetic communication capability (29C, 29D, 29E, 29N) has a GPS receiver (243) and a display (28a). The PCD requests maps (219) and location tagged data from data providers and other for display on the PCD.
