  In the ROM 6, in addition to the navigation program for executing the map display process, the route search process, etc., the ROM 6 has the first position according to the voltage value data indicating the first position and the second position on the display area. Calculating means for calculating a new road vector having an end point on a point existing on the first road vector passing through the closest position and a point existing on the second road vector passing through the position closest to the second position; As new means for adding new road vector data indicating the new road vector calculated by the calculating means to road layer data which is a set of existing road vector data, new indicating the new road vector calculated by the calculating means As an additional means for adding road vector data to road layer data, which is a set of existing road vector data, a CPU 7 or the like is provided. Program for are stored. This program further causes the computer to function as an adding means for adding new road vector data to the road layer data in association with the display mode data indicating the display mode.

  The basic operation of the navigation apparatus configured as described above will be described with reference to FIGS. 3 and 4. In the present embodiment, as shown in FIG. 3, the first road image indicating the first road image and the second road image indicating the second road image are displayed on the display 10. A description will be given assuming that the first position A in the vicinity of the road image and the second position B in the vicinity of the second road image are designated by the user.

  As shown in FIG. 4, the CPU 7 executes the program stored in the ROM 6 and reads the designated position calculation table stored in the HDD 5 (step S1).

  When the specified position calculation table is read, the CPU 7 executes the program stored in the ROM 6 and uses the specified position calculation table and the voltage data held in the RAM 8 to determine the specified position on the display area of the display 10. Calculate (step S2).

  When the designated position is calculated, the CPU 7 executes a program stored in the ROM 6 and stores designated position data indicating the calculated designated position in the HDD 5 (step S3).

  When the designated position data is stored, the CPU 7 executes the program stored in the ROM 6 and determines whether there is unprocessed voltage value data (step S4). Specifically, it is determined whether or not the voltage value data is held in the RAM 8.

  If it is determined in step S4 that there is unprocessed voltage value data (No in S4), the CPU 7 executes the program stored in the ROM 6 and executes the processing from step S1 to step S4. .

As shown in FIG. 5, the CPU 7 executes a program stored in the ROM 6 and determines whether or not the designated position is on the road vector using the designated position data and the road layer data stored in the HDD 5. (Step S10).

  If it is determined in step S10 that the designated position is on the road vector (Yes in S10), the CPU 7 executes the program stored in the ROM 6 and determines the designated position as an end point (step S11).

  On the other hand, if it is determined in step S10 that the designated position is not on the road vector (No in S10), the CPU 7 executes the program stored in the ROM 6 and sets a point on the existing road vector as an end point. Determine (step S12).

  For example, as shown in FIG. 6, since the designated position A does not exist on any road vector, the road vector closest to the designated position A is calculated, and the point A1 on the calculated road vector is the end point. Determined. Since the designated position B does not exist on any road vector, the road vector closest to the designated position B is calculated, and the point B1 on the calculated road vector is determined as an end point.

  When the end point is determined in step S11 or step S12, the CPU 7 executes a program stored in the ROM 6 and determines whether there is unprocessed designated position data (step S14). Specifically, it is determined whether or not designated position data is stored in the HDD 5.

  If it is determined in step S14 that there is unprocessed designated position data (No in S14), the CPU 7 executes the program stored in the ROM 6 and executes the processes in steps S10 to S14.

  On the other hand, if it is determined that there is no unprocessed designated position data, the CPU 7 executes a program stored in the ROM 6 and calculates a new road vector using the end point data indicating the determined end point ( Step S15). For example, as shown in FIG. 6, when the end point A1 and the end point B1 are determined, new road vectors having the end point A1 and the end point B1 as the start point and the end point are calculated.

  When the new road vector is calculated, the CPU 7 executes a program stored in the ROM 6 and additionally stores new road vector data indicating the new road vector in the road layer data stored in the HDD 5 (step S16).

  At this time, if the CPU 7 executes the program stored in the ROM 6 and additionally stores the new road vector data in association with the display mode data indicating the display mode, the CPU 7 is based on the new road vector data as shown in FIG. New road images are displayed with dotted lines, while existing road images based on existing road vector data are displayed with solid lines. Of course, the display mode may be varied depending on the presence or absence of blinking, the thickness of the line, or the difference in color.
