Abstract: A model transforming data generating portion 4 extracts parameter data corresponding to a given road area from two-dimensional map data in a two-dimensional map data storage portion 3. Subsequently, the model transforming data generating portion 4 reads out pattern data corresponding to the specified road area from a pattern model storage portion 5 and generates model transforming data. An image data generating portion 6 transforms a corresponding three-dimensional map display model by using the generated model transforming data to generate three-dimensional image data. The generated three-dimensional image data is given to and displayed in a display 7. The operator operates an input portion 2 on the basis of the contents displayed in the display 7 to correct the generated model transforming data.

Abstract: A terminal device for reading a cartographic file in which updating one cartographic file does not require updating cartographic files in the neighboring units. For this purpose, cartographic files which represent respective units extracted by dividing a map into a plurality of areas each comprise node records generated for respective nodes and link records generated for respective links. Given node records contain coordinate information about neighboring nodes which define connections of roads between its unit and a neighboring unit. The cartographic files are stored in a first storage device. The data processing portion executes a process of searching for a route by using the cartographic files. During the route search, the data processing portion traces the connection from a road in one unit to a road in another, neighboring, unit on the basis of the coordinate information about the neighboring nodes of said one unit and said neighboring another unit.

Abstract: In a navigation apparatus, a CPU searches for a plurality of routes from a starting point to a destination. These routes share the same starting point and the destination, but vary in their course along the way. Then for route selection, the CPU refers to position information provided by a locator to determine on which of the routes the user is now moving. In this manner, the navigation apparatus can automatically select one route from several derived through the route search.

Abstract: In order to implement a navigation device in which landmarks are much less monotonous, and the applicability thereof is wider, the navigation device of the present invention operates as follows. A landmark is displayed in either normal display (still) and emphatic display (animated) by referring to landmark information. Specifically, referring to for normal display is shape information and positional information in the landmark information, and for emphatic display, an emphatic display execution file therein is referred to. For emphatic display, a group of instruction described in the emphatic display execution file are interpreted and executed so that the landmark is animated.

Abstract: A navigation device at least includes a CPU and a detector generating a detection signal for determining whether a main device is used inside a vehicle or not. If determining, based on the detection signal from the detector, that the main device is used inside the vehicle, the CPU operates in on-vehicle mode to carry out first navigation (present position estimation and route search) suitable for use in the vehicle. Otherwise, the CPU operates in off-vehicle mode to carry out second navigation (present position estimation and route search) suitable for use outside of the vehicle. Thus, the navigation device can automatically switch its operation mode between on-vehicle mode and off-vehicle mode.

Abstract: In a navigation device assisting a driver of a vehicle to drive safely by presenting accurate information at the right time what is going on around his/her vehicle, an obstacle detection part detects any obstacle with the help of external information monitored by an external monitor part. By utilizing the vehicle's current position detected by an input part and a position detection part, and map data stored in a map data storage part, a route selection part searches for a route to a destination. Based on thus found route, current position, map data, and the external information from the obstacle detection part, a guiding part performs route guidance to the destination. A map data arranging part refers to the map data, information from the obstacle detection part and the input part, and object model display information from the object model display information storage part, and arranges any applicable object model onto a map data space.

Abstract: A vehicle position calculation unit (1) calculates a position of a vehicle on a plan view, and an estimate locus calculation unit (2) calculates an estimate movement locus of a vehicle body when the vehicle is moved at a maximum steering angle with respect to the vehicle position, and a display unit (3) displays the vehicle position calculated by the vehicle position calculation unit (1) together with the estimate locus of the vehicle body calculated by the estimate locus calculation unit (2). Thus, even a beginner driver of the vehicle can easily and quickly park the vehicle with accuracy and safety while monitoring the estimate movement locus of the vehicle on the display screen.

Abstract: In a route selection process, an optimal route searcher 5 refers to a traffic light flag included in route selecting data stored in a second storage 4 to see whether a target intersection has any traffic light or not. When the optimal route searcher 5 determines that the target intersection has a traffic light s, a traffic light cost calculator 6 calculates a traffic light cost relevant to a waiting time due to the traffic light s. Based on the traffic light cost thus calculated by the traffic light cost calculator 6, the optimal route searcher 5 calculates a passage cost relevant to a time taken for passing the target intersection. In this manner, with consideration for the waiting time due to the traffic light, a time for going through an entire route can be estimated with higher correctness, thereby rendering the route thus searched more optimal.
