FIG. 4 schematically shows an example of the data structure of the nth generation data set 322. In the present embodiment, the nth generation data set 322 includes a parcel data set 420 and a region data set 440.

The parcel data set 420 is used for drawing a map, guiding a route, and the like in the navigation device 182. The parcel-based data set 420 includes a plurality of data sets having different representation modes. Each dataset contains multiple map data. Examples of the expression mode include large and small scales.

According to the present embodiment, the map data constituting the parcel system data set 420 has seven levels (referred to as parcel level) of level 5, level 4, level 3, level 2, level 1, level 0, and level -1. It may be classified into).

In the present embodiment, the level 5 data set has a small scale of each map data, and the number of map data constituting the data set is small. As the level decreases, the scale of each map data increases, and the number of map data constituting the data set also increases. Details of the hierarchical structure of the parcel data set 420 will be described later.

The region data set 440 is used to calculate the route in the navigation device 182. In this embodiment, the region data set 440 has a hierarchical structure. According to the present embodiment, the route calculation data constituting the region data set 440 has seven levels (referred to as region level) of level 5, level 4, level 3, level 2, level 1, level 0, and level -1. It may be classified into).

FIG. 5 schematically shows an example of the hierarchical structure of the parcel-based data set 420. According to this embodiment, the recording range of the map is divided into a plurality of sections (sometimes referred to as basic parcels) having substantially the same shape and size based on, for example, latitude and longitude. The shape and size of the basic parcel will vary from level to level.

For example, in a level 5 dataset, the shape and size of the basic parcel 512 is determined so that the block 510 with the plurality of basic parcels 512 covers the entire recording range of the map. Each of the plurality of map data constituting the level 5 data set corresponds to each of the plurality of basic parcels 512. Each map data may be data for expressing a map of a geographical range corresponding to the basic parcel 512.

As shown in FIG. 5, in the level 4 dataset, each of the level 5 basic parcels 512 is covered by a block 520 having a plurality of basic parcels 522. Each of the plurality of map data constituting the level 4 data set corresponds to each of the plurality of basic parcels 522.

Similarly, in the level 3 dataset, each of the level 4 basic parcels 522 is covered by a block 530 with a plurality of basic parcels 532. Each of the plurality of map data constituting the level 3 data set corresponds to each of the plurality of basic parcels 532.

Similarly, in the level 2 dataset, each of the level 3 basic parcels 532 is covered by block 540 with a plurality of basic parcels 542. Each of the plurality of map data constituting the level 2 data set corresponds to each of the plurality of basic parcels 542.

Similarly, in the level 1 dataset, each of the level 2 basic parcels 542 is covered by a block 550 with a plurality of basic parcels 552. Each of the plurality of map data constituting the level 1 data set corresponds to each of the plurality of basic parcels 552.

Similarly, in the level 0 dataset, each of the level 1 basic parcels 552 is covered by block 560 with a plurality of basic parcels 562. Each of the plurality of map data constituting the level 0 data set corresponds to each of the plurality of basic parcels 562.

In this embodiment, the level 0 basic parcel 562 and the level-1 basic parcel 572 cover substantially the same geographical range. Each of the plurality of map data constituting the level-1 data set may be an enlarged map or a detailed map of each of the plurality of map data constituting the level 0 data set.

As shown in FIG. 5, according to the present embodiment, each of the plurality of map data constituting the parcel system data set 420 belongs to one of the plurality of levels defined by the scale, and is defined for each level. Corresponds to one of one or more basic parcels. Further, the map data belonging to two or more levels among the plurality of levels may be vector map data (sometimes referred to as vector data). On the other hand, the map data belonging to at least one of the plurality of levels may be raster map data (sometimes referred to as raster data). For example, in the present embodiment, the map data from level 5 to level 0 is vector map data, and the map data of level -1 is raster map data.

For example, the map distribution server 120 distributes map data from level 5 to level 0 unless instructed by the user. As a result, the communication capacity is greatly reduced. In addition, the amount of resources of the navigation device 182 used for updating the map is greatly reduced. On the other hand, the map distribution server 120 distributes level-1 map data in response to a request from the user. As a result, each time the map is updated, the communication capacity can be reduced or the navigation device 182 can be used without significantly impairing the user experience, as compared with the case where all the map data included in the map recording range is delivered. You can effectively use the resources of.

The correspondence with the road link ID used for identifying each is shown. Details of the VICS conversion table 658 will be described later.

As a result, even if the road link ID assigned to at least a part of the road links included in the recording range of the map is changed due to the update of the map data set stored in the map distribution server 120, the navigation device. The 182 can associate the road link ID in the map data set with the VICS link ID by using the VICS conversion table 658. As a result, for example, the navigation device 182 can reflect the road traffic information transmitted by the VICS signal 22 on the map.

Set the sensitivity of the touch panel so that it is smaller than the sensitivity of the area corresponding to the part to be used. The portion of the basic function selection area 1520 that satisfies the condition that the distance from the end of the operation selection area 1542 on the side of the basic function selection area 1520 satisfies a predetermined condition is, for example, the operation selection in the basic function selection area 1520. The distance from the lower end of the region 1542 is a portion larger than a predetermined value.

The input / output control unit 1222 is an area on the touch panel of the touch display 1212, and is between (i) the basic function selection area 1520 and the operation selection area 1542, and (ii) the side of the operation selection area 1542 of the basic function selection area 1520. A dead area that does not accept the user's touch input is arranged in the vicinity of the end portion of the above and in the region corresponding to at least one of the vicinity of the end portion on the side of the basic function selection area 1520 of the (iii) operation selection area 1542. The sensitivity of the touch panel may be set as such. For example, on the touch panel of the touch display 1212, the sensitivity of the touch panel is set so that the area corresponding to the gap 1544 of the screen 1500 becomes a dead area.
