An example navigation system enables searching for an optimum route through a one-time route searching process where several destination or departure locations exist. The navigation system includes a point of interest (POI) attribute information database for accumulating POI attribute information, a network data edit unit and a virtual node setup unit. The navigation system determines whether there is a plurality of POIs in a certain departure location and/or a destination location by making reference to relevant data in the POI attribute information database. If there are several POIs, the virtual node setup unit sets up a virtual node connected to each node of the plurality of POIs through links having identical link cost. The network data edit unit then adds the virtual node to the searching network data, and a route search unit functions to search for routes using the searching network data containing the added virtual node.

Navigation system, route search server, route search method and route search program

A navigation device performs a route guidance based on a route from a current location to a destination, the navigation device being connected to a server for searching the route. A navigation method for the navigation device includes sending a request for searching the route to the server and receiving information on the route from the server. The method also includes measuring an elapsed time from a start of the route guidance, and performing the route guidance based on the information received. The method further includes cutting off a communication with the server and coming into a standby state, upon a determination that the elapsed time measured has reached a predetermined time and when the route is being guided or a current location is being checked, to decrease a bandwidth usage between the navigation device and the server and to reduce a communication charge associated with the bandwidth usage.

The information distribution system includes an information distribution server, a mobile terminal, and a content DB. The content DB contains content information to be provided to the mobile terminal and information on the area to which the content is provided. The information distribution server distributes the content guide information to the mobile terminal. According to this content guide information, the mobile terminal performs a content distribution request. The information distribution server judges the position of the mobile terminal according to position judgment means. When the mobile terminal is in the distribution area of the content requested, the content is downloaded.

A map display device and a map display method, in which a building in a map is formed as a pseudo three-dimensional figure and arithmetic processing to display the figure as a bird's-eye view is simplified. The map display devicefor displaying map data, formed from vector data, on a display means has a plane figure-for-bird's-eye-view creation means, a shift amount storage means, a building position determination means, and a figure data copying means. The plane-figure-for-bird's-eye-view creation meanscreates, from the map data formed from vector data, a plane figure for creating a bird's-eye view. The figure data copying meanscopies and draws the plane figure to display a bird's-eye view. This is performed based on the positions of buildings determined by the building determination meansand on the shift amounts stored in the shift amount storage means, and in this process, the plane figures are shifted upward on a display screen according to the shift amounts, and the copying and drawing are made one by one from a building positioned on the far side in the bird's-eye view.

Map display device and map display method

A navigation device performs a route guidance based on a route from a current location to a destination. A communication controller sends a request for searching the route to a server. A guidance-information receiving unit receives information on the route from the server. A time measuring unit measures an elapsed time from a start of the route guidance. A guidance controller performs the route guidance based on the information received. The communication controller commands the navigation device to cut off a communication with the server and to stand by upon a determination that the elapsed time measured has reached a predetermined time and when the route is being guided or a current location is being checked by the guidance controller, to decrease a bandwidth usage between the navigation device and the server and to reduce a communication charge associated with the bandwidth usage.
