[0029] A second embodiment of the present invention is to provide a map management system in which map data is obtained on an area basis, more specifically, on a county basis, city basis, or the like, and map data for each acquisition unit can be collectively managed. The basic configuration of the map management system according to this embodiment is the same as that according to the first embodiment.

[0030] The map editing and displaying device may request the center to send back map data of an area including a certain county, a certain city, a certain town, or a certain street. For example, the map editing and displaying device may send a request to the center: "We need a map of Saitama Prefecture", "We need a map of Kawagoe City and Tsurugashina City", or "We A map of KAWAGOE City, Shinjukucho (ARAJUKUMACHI) 1 is required." The center compiles and displays map data for all areas requested by the device to the map, each area including a county, city, town or street.

Abstract

The county names and several city names of the address index data of the area where the map data has been obtained are compared with those of the address index data of the entire country. Based on the comparison result, a map name corresponding to the range of the obtained map data is automatically assigned to the obtained map data. By displaying these maps in a list or the like, the user can easily recognize the maps. Furthermore, an area whose address index data includes all address index data of the requested county, requested city, or the like is calculated, and the map data of the area is submitted. This allows the user to obtain only necessary map data without performing a complicated operation of determining an area. Thereby, there is provided a map editing and display device which, when partial map data has been obtained on an area basis, allows the user to easily recognize the area of ​​the obtained partial map data, and also allows the user to easily identify the desired map data.
