A system and method provides data representative of geographical information to equipment for providing weather-related information, such as a NOAA weather radio (NWR). A telephone call is placed over a telephone network from the equipment to an information server, which receives information corresponding to an origin of the telephone call in conjunction with the telephone call. The received information is processed to generate data representative of geographical information, which is then sent to the equipment in conjunction with the telephone call. The equipment is then programmed using the data representative of geographical information to provide geographically based weather-related information.
