When the registration pointer is moved and clicked on a position where the landmark is to be displayed on the original map, a landmark registration dialog shown in FIG. 9 is displayed. In this dialog, a landmark name and a memo are input and an icon image to be displayed is selected. When the client clicks the update button, the landmark data 68 stored in the storage means 6 of the location information management server 2 is updated and stored together with the longitude / latitude information of the landmark.

  After the client setting as described above is completed, the client setting data acquisition unit 82 acquires the client setting data 63 stored in the storage unit 6 (step S6). At this time, a layer number to be displayed is acquired from the display layer specifying data 66, and a moving body number for actually acquiring position information is acquired from the moving body specifying data 67. Further, the icon number is acquired from the landmark data 68 and the corresponding icon image is acquired from the icon data 65.

  Next, the display layer acquisition part 83 acquires a display layer from the map layer data 62 stored in the memory | storage means 6 based on the layer number acquired by step S6 (step S7). In this state, when the client clicks the regular positioning button 110 or the arbitrary positioning button 111 to instruct the start of positioning (step S8), the position information acquisition request unit 84 sets the mobile body number acquired in step S6. It transmits to the positioning server 4 and requests position information (step S9). At this time, the position information acquisition request unit 84 acquires an access ID and an access password from the client information data 61 that specifies the client, and accesses the positioning server 4 by these.

  The positioning server 4 acquires the mobile body number after authenticating the position information management server 2 with the access ID and access password transmitted from the position information acquisition request unit 84. Then, the position information acquisition unit 41 of the positioning server 4 gives a positioning instruction to the specific moving body 5 corresponding to the moving body number, thereby acquiring the position information (step S10). When the regular positioning mode is instructed from the client, the time interval for positioning is registered in the mobile unit 5, and the position information that is automatically reported every time interval is acquired.

  Subsequently, when the position information transmission unit 42 transmits the position information regarding the specific moving body 5 to the position information management server 2 (step S11), the position information acquisition request unit 84 on the position information management server 2 side receives the position information. Is acquired (step S12), stored in the history data 64, and output to the original map information generation unit 85. Thereby, the original map information generation unit 85 is based on the position information received from the position information acquisition request unit 84, the display layer acquired by the display layer acquisition unit 83, and the landmark acquired by the client setting data acquisition unit 82. The original map information is generated (step S13).

  The original map information distribution unit 86 distributes the original map information generated by the original map information generation unit 85 to the client terminal device 3 (step S14). The client terminal device 3 that has received the original map information displays an image on the display as an original map by the original map information display unit 33 (step S15). Thereby, the positional information regarding the specified moving body 5 and the predetermined landmark are displayed on the original map.

  According to the present embodiment as described above, since the map database, mapping engine, and the like are all constructed on the location information management server 2 side, the client can use this system as long as there is an environment that can be connected to the Internet. it can. This is a great advantage in terms of simplicity and cost.

  In addition, since the map database update work and the server maintenance work are all performed on the location information management server 2 side, a system administrator is not required on the client side, so that work efficiency can be improved and costs can be reduced.

  Furthermore, since only the necessary layers can be selected and combined according to the purpose of use of the client and the occasional necessity, and an original map can be generated, the position information of the mobile object 5 can be simplified quickly and appropriately. Can be practically used.

  Furthermore, since it is only necessary to create a detailed map of a local area such as a small municipality according to the client's request and sequentially link it to the national map, it is possible to obtain detailed geographical information even in an area away from the urban area. This is because it is only necessary to create a detailed map of the necessary scale for each local government according to needs and link it to the main map database. It is possible to construct a system that can use detailed map information.

  The location information management system 1, the location information management server 2, and the location information management program using the original map according to the present invention are not limited to the above-described embodiments, and can be changed as appropriate.

  For example, in the present embodiment described above, a layer that can be displayed in advance is registered in the map layer data 62. However, the present invention is not limited to this, and rivers, public facilities, convenience stores, banks, and the like according to client requests. These layers may be appropriately added, and conversely, unnecessary layers may be deleted. In the present embodiment, the positioning server 4 is separately provided to acquire the position information of the moving body 5. However, the present invention is not limited to this, and the position information management server 2 has the function of the positioning server 4 as an application. By providing the position information, the position information may be acquired directly from the moving body 5.
