Abstract: A structure configuration map display system includes a controller for depicting and displaying a structure configuration map based on structure configuration map information. The system provides for searching and guidance relative to a structure designated as a target point. A display form corresponding to the structure information for the target point is determined and the display form of the target point is changed based on the results of that determination and is displayed so that a user can easily recognize the desired facility by its display form which corresponds to stored structure information. Also, the user can easily identify a facility as the desired facility and can obtain reliable guidance to that target point by the display form which indicates the type of the structure.

Abstract: A navigation system including a present-position sensing system for sensing a present position; information storage medium for storing map information; an input device for entering into the system the destination, a roundabout point, a bypass, and the location desired to be traversed for entry of input indicating the execution of a route search from the present position sensed by the present-position sensing system to the destination; an output device for outputting information route guidance; and a central processing unit including a route searching capability for searching for a route to the destination; a route storage capability for provisionally storing the identified route; and route guidance control for sending a signal for performing route guidance to the output device. When the roundabout point or bypass is entered in the system, a search cost for roads and intersections near to the roundabout point or bypass is raised so that route search processing can be performed. When the location desired to be traversed is set, roads near to the location desired to be traversed are retrieved for search purposes. In travel guidance, a present-position mark is displayed in either a continuous mode or a blinking mode depending on the state of travel.

Abstract: A navigation system for vehicles, capable of exactly and quickly showing guide information to a driver when two intersections to be negotiated are close to each other, is provided. A destination is input by an input part and a route to the destination is calculated from a present position of a vehicle, calculated by a present position determiner, by a route calculator included in a calculation section. The calculated route is stored in a route memory. A route guide controller included in the calculation section reads map information around the vehicle, stored in a guide information memory within a map information storage section and superimposes the map information with the present position of the vehicle, a traveling direction and the route stored in the route memory to display the superimposed information on a display. When the vehicle approaches the intersection, the screen is changed with an intersection map, but, when a next intersection map is required, the next intersection map is drawn on the back screen and is displayed by changing the two screens after the vehicle passes through the first intersection.

Abstract: A navigation apparatus has an input unit (1), a CPU (2), a display unit (3) and a memory unit (4), the memory unit (4) being a memory such as a CD-ROM in which network data of geographical points, namely destinations and present locations, and information are stored in advance. Also stored are map data (10), an intersection list (11), a destination list (12), road data (13) and a region name list (14), etc. When a destination is designated by an input from the input means (1), the CPU (2) performs an exchange with a program, stored in a ROM (9a), in order to set information for travel to the destination by course exploration in accordance with each geographical point stored in the memory unit (4). This information is stored in a memory such as a RAM (9b). In an embodiment, the RAM (9b) is provided with a non-volatile area for storing departure-point data (east longitude, north latitude, etc.). When an input is made by a reset switch in entering a departure point, the data in this non-volatile area can be rewritten. Data written in are preserved until the reset switch is pressed again and a geographical point is entered. Data will not be erased even if an ignition switch is turned off.
