GPS map data on golf courses is collected in a database, through a network when necessary. GPS golf-course map data is sent to users through the network. The fee to be paid by each user and the payment to be made to the person or organization that has the right to the map data is controlled. A golf player can obtain GPS golf-course map data on various golf courses in the same way, easily and at a low price, using a user terminal device, making use of GPS golf-course map data for play by manipulating the user's own user terminal device. Optional information is added to GPS golf-course map data, which the user can choose as needed. Optional information can also be presented based on the records of use of a particular user.
