Abstract
A portable terminal apparatus which can communicate one's current location on a map and an associated message to the party on the other end of a cellular phone line. In the apparatus, a positional information acquiring device acquires positional information. Then, a transmitting device transmits the acquired positional information along with an associated message to other portable terminal apparatuses. Further, a receiving device receives the positional information and message transmitted from other portable terminal apparatuses. Then, a map data acquiring device acquires the map data in a predetermined range including the location shown by the received positional information. A displaying device displays the map data together with a mark that indicates the position shown by the received positional information.
