This registers the exact coordinate value on the map at the position specified on the map displayed on the screen in S3 as the X coordinate value and the Y coordinate value of the corresponding item of the ledger file 7 in FIG. . As a result, the item (for example, Co., Ltd.) and the accurate coordinate value on the map are automatically registered in the ledger file 7 in association with each other.

In step S5, color-coded display is performed on the screen. In this method, the accurate coordinate values on the map obtained in S2 to S5 are color-coded and highlighted on the map on the screen to prompt the user to confirm.

As described above, the user simply designates the position of specific information (for example, “Co., Ltd.”) on the map on the screen by using a mouse or the like, and the information on the map is accurately associated with the information (item). It is possible to automatically register various coordinate values. In particular, when the coordinates of each point of the map displayed on the screen are not equally divided, and it is necessary to interpolate the coordinates inside the four corners of the reference block from the accurate coordinate values, conventionally, Although a skilled user has visually input accurate coordinate values on the map, in the present embodiment, the designated coordinate values on the screen are automatically changed to four of the blocks on the map including the designated point. Interpolation based on the exact coordinate values of corners to obtain accurate coordinate values and automatically register them in the ledger, or display them on the map on the screen and prompt confirmation to simplify more accurate coordinate values on the map In addition, automatic registration can be reliably performed.
