[0002]

2. Description of the Related Art A digital map system currently used inputs an address of a region to be searched by a computer keyboard or the like, and displays a digital map centered on a point corresponding to the address on a computer display. is there. That is, the digital map system has a built-in database including address data, coordinate data corresponding to the address, building shape and coordinate data, road and river coordinate data, and the like. Then, a digital map of a portion corresponding to a desired address is displayed on a computer display. Alternatively, some digital maps indicate a position corresponding to the input address in the displayed map.

[0003] On the other hand, the land prices of land are published by the National Taxation Bureau as a map shown on a paper medium. A person seeking a valuation of a land finds the portion of the map where the target land is indicated, reads the road value of the road on which the target land faces, and uses the road value to calculate various values. It is necessary to perform calculation work. A digital map of a road price is also available on the market, but it is the same as the case of a paper map that a person must search for a target land.

[0004]

The address may be changed due to merger of municipalities, change of street name, etc.
Image data on a digital map also needs to be updated frequently due to land readjustment and building replacement. However, in the conventional digital map system, the address data and the digital map image data are integrally formed, and the address is not associated with the absolute coordinate data such as the latitude and longitude. There is a problem that it is difficult to combine a database with image data of various digital maps. Therefore, for example, even when a town name is changed in one town, it is necessary to change the database built in the digital map system as a whole. As a result, the work of updating the database of the digital map system becomes enormous, and there is a problem that it is difficult to constantly update the digital map according to the actual situation.

[0005] Further, since the road price is changed every year, it is necessary to update the system every year. However, every time the road price is updated, there is a cost burden for system maintenance in which the entire database is re-created. There is a problem that it becomes larger.

It is an object of the present invention to provide an address position indicating system having a database storing addresses which can be easily combined with image data of various digital maps. A second object of the present invention is to provide a road price display system that can easily update data in accordance with a road price published every year.
