摘要： PROBLEM TO BE SOLVED: To easily set points such as destinations or the like by selecting telephone number information in which position information corresponding to received telephone number information is stored, and displaying the information to a screen. SOLUTION: A navigation apparatus 1 receives telephone number information including at least telephone numbers of a portable telephone 20 via a communication I/F 21-a communication I/F 11 from the telephone 20 having a memory 26 in which the telephone numbers inputted by a user are stored. The apparatus distinguishes telephone numbers and telephone numbers having position information stored by the received telephone number information from guide information stored in a memory device 5, stores searched guide information to a memory of an operation process part 2 and sets a display mode. When the user selects the mode when setting a destination (a bypass point), a list of telephone numbers or related names is displayed to a screen. When the user selects the telephone number or name as the destination (bypass point) from the screen, position information corresponding to information on the selected telephone number is set as the destination (bypass point).

摘要： PROBLEM TO BE SOLVED: To erase the hidden surfaces of map data fast without special hardware by controlling a process for dividing the map data in mesh units according to whether or not there is a hidden surface in a three-dimensional map. SOLUTION: The map data of a map, roads, character strings, etc., are divided into geographical meshes 2001 constituting a geographical surface and the geometrical meshes and divided map data are drawn in order from far away from a viewpoint to nearby the viewpoint to display a three-dimensional map on an output device 2. A geometrical mesh arithmetic means calculates a visible area of the map displayed on the display screen from the viewpoint position and elevation angle and generates rectangular geometrical meshes representing the geometrical surface from altitude data present in the visual area. A hidden-surface presence/absence decision means performs projection conversion by a projection converting means for the generated geometrical meshes and decides whether or not a geometrical mesh which becomes a hidden surface from the conversion result, and when the geometrical mesh which becomes the hidden surface is present, a map data dividing means divides road data and background data included in the map data in geometrical mesh units.

摘要： PROBLEM TO BE SOLVED: To selectively provide advertisement information of high use value that a user desires on the spot in addition to information that the user specially designates so that the user in movement can obtain information having high usability. SOLUTION: This system is equipped with a server 2 which provides service information such as weather information and traffic information, and a mobile terminal 1 which outputs the service information provided by the server 2 to a user. The mobile terminal 1 sends individual information including current position information to the server 2 through a communication line 3. The server 2 receives the individual information sent from the mobile terminal 1 and detects advertisement information stored on the server 2 by relating to the inside of a specific range from the point specified with the current area information. Then the detected advertisement information is sent to the mobile terminal 1 through the communication line 3.

摘要： PROBLEM TO BE SOLVED: To enable a three-dimensional scenic view with a guide crossing always indicated to be displayed by enabling direct bird's-eye viewing of the guide crossing to be displayed and by setting a visual point at a position on a guide path. SOLUTION: If the three-dimensional scenic view 2007 of a crossing to be guided and a guide arrow 2006 overlapping the view are displayed on a display, a scenic view the same as a scene which a driver has a bird's-eye view of the guide crossing from a road where he passes is displayed on the display, whereby the driver can easily determine a guided direction. Parameters to be predetermined at the time of having a bird's-eye view of the guide crossing include a visual point position 2003. When the three-dimensional scenic view is to be displayed, in order to inform the driver of a shape of the guide crossing in advance, the visual point position may be desirably set at an own vehicle position 2004 or on the guide path 2001 closer to the guide crossing 2002 than the own vehicle position. Thus it is always possible to display the three- dimensional scenic view with a bird's-eye view on the guide crossing 2002, whereby the driver can easily recognize a guided direction.

摘要： PROBLEM TO BE SOLVED: To display the current position of a vehicle along a road drawn in three dimensions even if the positioning accuracy in the direction of height is low by calculating the altitude of a vehicle according to the altitude data contained in map information at the time of superposing the vehicle position on a three-dimensional map displayed according to a three-dimensional map information. SOLUTION: A navigation device comprises a processing part 34 including a current position calculating part 51, a position correcting part 52, a data reading-in part 53, a visual point setting part 60, and a display processing part 61. When the current position of a vehicle is updated, the position correcting part 52 calculates the position on the two-dimensions according to the current position data obtained by the current position calculating part 51 and the peripheral map data obtained through the data read-in part 53, and calculates the altitude of the vehicle from the altitude data on the map data according to the position by a designated method. The obtained three-dimensional coordinates are given to the display processing part 61 to obtain an image in which the vehicle position is superposed on the three-dimensional display map according to the setting in the visual point' setting part 60.

摘要： PROBLEM TO BE SOLVED: To display a stereoscopic map without any sense of incompatibility regardless of the presence of the height information of each map element. SOLUTION: The three-dimensional model of geography is prepared based on altitude data included in map information registered in a database (a step 400), and whether or not height information is included in the shape data of each map element of attribute information registered in the database is judged (a step 401). Then, when the height information is included in the shape data, the three-dimensional model of the map element is prepared by using the shape data (a step 403), and when the height information is not included in the shape data, the three-dimensional model of the map element is prepared by using the shape data and the height information calculated from the altitude data included in the map information registered in the database.
