Abstract
A server unit () recognizes a travel route search request together with a current position information and a destination information from a terminal unit () over a network () and searches for a travel route with use of a matching data of a map information. The server unit () sends a matching mesh information including a node and link that represent a road corresponding to the travel route and a display mesh information for areas other than the areas represented by the matching mesh information together with the information for the travel route to the terminal unit () over the network (). The terminal unit () displays a road based on the matching mesh information and the information excluding the road based on the display mesh information on a terminal display. Thus, the information amount of the map information to be processed can be reduced thereby improving the processing efficiency.
