<p>The invention concerns a system for providing distance information in which a portable terminal (I) transmits its own positioning data obtained from a GPS receiver (5) to a central apparatus (21) via a communication system (22). The central apparatus (21) reads out course information pertaining to a golf course where a player (2) is playing from a course information stored in advance. Then, in relation to this specified course information, distances between the portable terminal (1) and preassigned registered points, for example pins, ponds, bunkers, etc. are transmitted to the portable terminal (1). Consequently, a player (2) holding the portable terminal (1) can determine his relative position to any point of the golf course, accurately and on a personalized basis. <IMAGE></p> |
