[0012]
FIG. 2 is a block diagram showing a specific hardware configuration for realizing the basic means of the navigation device shown in FIG. The DVD 20 is a disk corresponding to the map information storage medium 11 in FIG. 1, and the drive 21 is a disk drive corresponding to the map information acquisition unit 12 in FIG. The GSP receiver 22 corresponds to a part of the input unit 13 in FIG. An interface (I / F) circuit 23 includes a drive 21, a GPS receiver 22, and map information and current position information input from sensor devices (not shown) such as a vehicle speed sensor for detecting vehicle speed and a gyro for detecting azimuth. The data is converted into a data format that can be processed in the navigation device.
[0013]
The navigation ECU 24 controls the entire navigation device, and has a built-in ROM (not shown) having a ROM storing a control program and a register for data processing. The external memory 25 is, for example, an HD (hard disk), and stores data of map information and position attribute information input from the drive 21 via the I / F circuit 23. The operation unit 26 corresponds to a part of the input unit 13 in FIG. 1, and inputs a command by a user operation to the navigation ECU 24. The display 27 corresponds to the display unit 17 of FIG. 1 and displays data of map information output from the navigation ECU 24 and other data necessary for navigation. The speaker 28 generates a sound related to navigation output from the navigation ECU 24.

For example, as shown in the figure, in the location attribute storage area corresponding to the display facility data 406 of “xx station”, the location attribute information of “subway △△ line” is stored. In the route search data 410, a line name corresponding to the background line data 402 is stored for route search.
[0017]
FIG. 5 is a flowchart showing the operation of the navigation ECU 24 as the position attribute determining means 14, the display order determining means 15, and the display data editing means 16. In step ST501, a predetermined position (for example, the input “XX station” of a subway) and a data type are obtained from the operation unit 26 as the input unit 13. The data types are the background line data, the background plane data, the display facility data, and the search facility data shown in FIG. Next, in step ST502, map information at a predetermined position is read from the DVD 20 based on the predetermined position and data type, and stored in the external memory 25.
[0018]
Next, in step ST503, with reference to the position attribute storage area corresponding to the map information of the predetermined position, one of the ground, underground, sky, and sea is determined as the position attribute of the predetermined position. Next, in step ST504, map information corresponding to the position attribute of the predetermined position is edited as display data. Prior to this editing, if there are a plurality of types of map information, the display order of each type and the display mode of each type of map information are determined.
[0019]
FIG. 6 shows an example in which map data of an underground including subway lines and stores in an underground mall and map data on the ground are superimposed and displayed. In this case, the underground map 31 is displayed by a solid line, and the above-ground map 32 is displayed by a dotted line to distinguish them. Alternatively, the map on the ground and the map on the basement may be displayed in different colors. In this display screen, for example, when the position of the “XX station” of the subway is designated by the cursor 33, a figure in which the subway line is deformed (modified) is displayed. FIG. 7 is a diagram in which the subway line including the designated subway “XX station” is deformed and edited.
[0020]
FIG. 8 is a diagram illustrating a display example when the position attribute is on the ground, in the sky, and on the sea. For example, in a case where an airplane is used from Itami Airport to Haneda Airport, it is assumed that the user is traveling to Itami Airport by car. When the position attribute of the air route is specified on the screen on which the map on the ground is displayed, an air route map 42 is displayed on the map 41 on the ground as shown in FIG. In this display screen, when an air route of "Itami Airport-Haneda Airport" is specified by the cursor 44, the specified air route is displayed. Alternatively, when the position attribute of the route of the ship is designated, the route map 43 of the ship is displayed on the map 41 on the ground.
[0021]
FIG. 9 is a diagram of a display screen for selecting information on an air route. On this display screen, for example, when the information on the departure flight from Itami Airport and the calculation of the time required from the current location to the Itami Airport is specified, as shown in FIG. The required time is displayed. The user may decide an airplane to be used on this display screen or make a reservation for the airplane.
