摘要:
A map displaying apparatus is provided with: a memory device for storing map data including road data and name data;. a map displaying device for displaying a map within a map display range by using the map data; a point determining device for determining one point or a plurality of points within the map display range; and a searching device for extracting the name data related to the specified point or points by searching the map data stored in the memory device. The map displaying apparatus is also provided with a name displaying device for displaying the extracted name data by superimposing the extracted name data on the map displayed by the map displaying device.
