摘要 |
A prefecture name and names of cities of address index data of map-data-acquired area are compared with those of address index data of the whole country. A map name corresponding to the range of the acquired map data is assigned automatically to the acquired map data on the basis of a comparison result. A user can easily identify a map by displaying such map names in list form or in a like manner. Further, an area whose address index data include all address index data of a requested prefecture, a requested city, or the like is calculated, and map data of that area are delivered. This allows a user to acquire only necessary map data without the need for performing a complicated operation of determining an area. Thus it is provided a map editing-and-displaying apparatus that allows a user to easily recognize an area of acquired partial map data when the partial map data have been acquired on an area basis and that also allows a user to easily identify desired map data.
