1. A locating and map downloading system comprising:
- a personal digital communicator comprising;
a display for the display of may information and selectable waypoints, the selectable waypoints being displayed with respect to the map information;
a receiver for receiving GPS signals;
means for processing the GPS signals whereby location of the personal digital communicator may be determined;
a first transceiver;
a first modem coupled to the transceiver and to a first digital processor;
communicator input means for formatting a request for map information, and for selecting a waypoint, the communicator input means coupled to the first digital processor;
the first digital processor being programmed to cause display of may information and selectable waypoints by the display, and to cause transmission via the first modem and the first transceiver of requests for map information and requests for additional data associated with a selected waypoint; and
a map storage and transmitting device comprising a second transceiver, a second modem coupled to the second transceiver and a second digital processor, memory accessible by the second digital processor for storing map information, waypoints, and additional data associated with the waypoints, the second digital processor being programmed to determine which map information stored in the memory is responsive to the request for map information and to cause transmission via the second modem and the second transceiver of map information responsive to the request.

Abstract
A location tagged data provision and display system. A personal communication device (PCD) with electromagnetic communication capability has a GPS receiver and a display. The PCD requests maps 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 data bases and then automatically transmitting data responsive to the requests to the requesting PCD.
