- 16 is an operation means comprising cursor movement keys and the like.
- Reference numeral 17 denotes information taking means for taking in-facility road information supplied from outside.
- the in-facility road information is created in a square area with the reference point Z as the origin of the local coordinate system, as shown in Fig. 4, and includes a connection point with the main road (facility entrance). And obtain the latitude and longitude of the connection point I from the latitude and longitude of the reference point Z, and obtain the connection point I with the map data contained in the CD-ROM.
- A is the data creation range of the outside road
- B is the search range of the road link for finding the connection point.
- the map data included in the CD-ROM is divided into rectangular areas, and the coordinates in each rectangular area are stored in a normalized (value between 0 and 1) form.
- the map data Must be obtained for the mesh number and the normalized coordinates.
- the method of calculating the mesh number of the lowest layer including latitude 0 longitude ⁇ is

At the same time, a guidance route to the set destination is derived based on the read guidance map data, and the derived guidance route is included in the guidance map displayed on the display unit 15. Is displayed.
- the process proceeds to the in-facility road guidance search.
- a virtual node to be replaced with the connection point I is created.
- the in-facility road information uses the weights from the destination to each node (Fig. 10) because the destination in the facility is predetermined at the time of information registration. Calculate in advance and remember the value in parentheses. At this time, the minimum value of the weight of each node is described from among the candidate weights. Remember.
- the information capturing means 17 in order for the information capturing means 17 to capture the in-facility road information from the outside, the smaller the data amount is, the better the data transfer time is.
- various attribute data is required, and the amount of data is enormous. Also, the required information differs depending on the mining algorithm.

- the in-facility road information used in the first embodiment is information that is hard to make public because it is private information. Therefore, it is necessary for the facility owner to encrypt the in-facility road information and provide it to the user, and this is achieved in the second embodiment shown in FIG.
- 21 is a facility owner
- 22 is a host computer that encrypts the premises map information provided by the facility owner 21 with an encryption key (public key)
- 23 is a host computer. Use of the map information on the premises is permitted between the facility owner and the navigation device provided by the person who has the decryption key.24 is the facility owner 21.
- the map information on the premises is encrypted and stored by the owner 21. It is a storage medium.
- the host computer 22 When using the host computer 22, first, those who use the on-site map information receive permission from the facility owner to use it in advance, and the facility owner informs the host computer 22 of the permission. Notice.
- the host computer 22 receives a request for using the on-site map information, the host computer 22 determines whether the requester has been granted permission by the facility owner, and If so, the encrypted site map information is sent to the navigation device 23. Those who use this information return the encrypted on-site map information with the decryption key and use it.
- a person who does not exchange information with the host computer 22 receives a storage medium 24 in which the in-facility map information has been encrypted and stored from the facility owner, and uses the storage medium 24 for navigation. The information stored in the storage device is read out, and this information is returned to the original information using the decryption key and used.
- the second embodiment by encrypting the in-facility map information and providing it to the user, it is possible to prevent the secret leakage in the facility as much as possible and to reduce the in-facility map. Using the information, it is possible to search for guidance routes even in facilities. Industrial applicability
- the navigation device uses the in-facility road information to search for a guidance route, so that, for example, map matching can be performed even in a facility such as a factory or a public facility. It is suitable for door-to-door route search.
