The center device 21 reads out information of courses on a golf course and the courses, where a player 2 plays, from the information of the courses beforehand stored and managed. Based on the information of the courses specified, distances from one's own positioning data to registered points, for example, pins, ponds or sand traps, which are beforehand appointed, are transmitted to the portable terminal 1 for transmitting one's own positioning data. Thereby, the player 2 who owns the portable terminal 1 can individually and precisely grasp the location from a playing point to each point in the golf course.</p> |
