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. The data providers respond to requests by using searching and sorting schemes to interrogate databases (245) and then automatically transmitting data responsive to the requests to the requesting PCD.
