1. A map editing apparatus for editing partial map data acquired from a map database, the map editing apparatus comprising:
- a control section connected to a map data storing section which stores address index data of a whole country, wherein the map data storing section comprises a recording device, andwherein the address index data of the whole country has a tree structure, and includes name data of states, name data of cities which are children of each of the states, name data of towns which are children of each of the cities, and name data of streets which are children of each of the towns; and
wherein the control section executes;
a checking process for checking the name data of cities related to the partial map data by using address index data appended to the partial map data;
an obtaining process for obtaining a number of cities included in the address index data appended to the partial map data per state, for each of the states corresponding to the name data of the cities obtained by the checking process, by using the address index data of the whole country and the name data of the cities obtained by the checking process;
an obtaining process for obtaining a total number of cities per state for each of the states by using the address index of the whole country; and
an assigning process for assigning the name data of a state, in which a proportion of the number of the cities included in the address index appended to the partial map data per said state to the total number of the cities per said state is equal to or greater than a predetermined ratio, to the partial map data.

Abstract
Provided is a map editing-and-displaying system that acquires partial map data from a database that contains map data. The partial map data includes appended index data. The system automatically assigns a map name to the partial map data based on the appended index data. A user can then identify and select the map according to the assigned map name.
