Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples.
The server system and the client system are computers, and each of the means is a means realized by reading and executing a computer program necessary for the CPU of the computer. FIG.

  FIG. 1 is a system configuration diagram showing an example of an embodiment of a map distribution system to which the present invention is applied. The map distribution system includes a map database 102, a POI database 103, and a POI display image database 104. The server system 101 includes a storage device for storage, and a plurality of client systems 105 that access the server system 101 via the Internet. When the URL of the server system 101 is input from the WEB browser 106 of the client system 105, the application 107 is downloaded to the client system 105 and can be operated.

  In the server system 101, the POI data is registered in the POI database 103, and the POI registration unit 111 that updates the POI display image data corresponding to the position of the POI data, and the map acquisition unit 112 that reads the map data from the map database 102. A POI acquisition unit 113 that reads POI data from the POI database 103, and a POI image acquisition unit 114 that reads POI display image data from the POI display image database 104, and the application 107 downloaded to the client system 105 is POI data. The POI definition unit 121 that defines the map data, the map search unit 122 that performs a search request for map data and POI display image data, and the map data acquired by the map search request and the POI display image data are displayed in a superimposed manner. It comprises a diagrammatic representation unit 123, a POI search unit 124 which performs an acquisition request for POI data from the position on the map, the POI display unit 125 displays the acquired POI data.

  The map database 102 includes a map management unit 201 and a map image file group 202 as shown in FIG. For example, when configuring a map database according to a 19 plane coordinate system, the map management unit 201 holds information on each system. The system information means the system origin coordinates 211 and the file path 212 to the map image file 223 corresponding to the system. On the other hand, the map image file group 202 is composed of a map image file 223 having a horizontal size of 200 pixels and a vertical size of 150 pixels classified for each scale 221 and system 222. The map image file represents an area of 200 m in width and 150 m in length, in which a range of 320 km in the horizontal direction and 600 km in the vertical direction centering on the origin of the system is divided into 1600 in the horizontal direction and 4000 in the horizontal direction. The image file name is “system number + mesh number in X direction + mesh number in Y direction + extension”. If the system number is the alphabetical order number (indicated as A for system 1), and the X and Y mesh numbers are represented by 4 digits starting with 0, the map image file name at the bottom left of system 1 is “A00000000.jpg”. .

For example, in the case of customer information, the POI database 103 includes a customer identification number 301, a POI coordinate value 302, a name 303, an address 304, and an entry date 305 as shown in FIG.
The POI display image database 104 has the same structure as the map database 102. That is, as shown in FIG. 4, it is composed of a POI display image management unit 401 and a POI display image file group 402. The POI display image management unit 401 holds the system origin coordinates 411 and the file path 412 to the POI display image file 423 corresponding to the system in order to manage the system information. Similar to the map image file 223, the POI display image file 423 has an image size of 200 pixels horizontally and 150 pixels vertically classified according to the scale 421 and the system 422, but is a transparent image format for use on the map. Take. The name of the POI display image file is the same as that of the map image file 223, and the name of the image 1 lower left POI display image file is “A00000000.png”.

Hereinafter, the operation of the map distribution system configured as described above will be described.
FIG. 5 is a processing flow at the time of POI data registration. When the coordinate position, name, address, and date of enrollment are input by the POI data definition unit 121 of the client system 105 and the input data is passed (transmitted) to the POI registration unit 111, the POI registration unit 111 starts with the POI database 103. The input data is registered in (501). Next, the system number (502), the X-direction mesh number (503), and the Y-direction mesh number (504) are obtained from the coordinate position input for each scale, and the POI display image file name to be updated is acquired. . Further, the target file is opened from the acquired POI display image file name (505), the pixel color index corresponding to the coordinate position of the POI display image file 223 is updated (506), and saved (507) is repeated. That is, POI data and POI display image data are created together when POI data is defined.

  As shown in FIG. 6, the generated POI data display processing flow is such that an address is input by the map search unit 122 of the client system 105. The map search unit 122 first calls the map acquisition unit 112 to request map image data using the input address and scale as parameters. The map acquisition unit 112 converts the received (received) address into a corresponding coordinate value (601), and from the converted coordinate value, a system number (602), an X direction mesh number (603), and a Y direction mesh number (604). ) And the URL (605) of the corresponding map image file 223 is returned (returned) to the map search unit 122 from the scale. Next, the map search unit 122 calls the POI image acquisition unit 114 to request POI display image data using the address and scale as parameters. The POI image acquisition unit 114 converts the received (received) address into a corresponding coordinate value (611), and from the converted coordinate value, a system number (612), an X direction mesh number (613), and a Y direction mesh number ( 614) is returned from the scale and the URL (615) of the corresponding POI display image file 223 is returned (returned) to the map search unit 122.

  Next, the map search unit 122 calls the map display unit 123 using the acquired two URLs as parameters. First, the map display unit 123 reads map image data from the URL of the received (received) map image file and displays it on the WEB browser 106 (621). When displaying an adjacent map image according to the display area, the mesh number of the file name is added or subtracted to generate the URL of the target map image file (622) and additionally displayed (621).

  Next, the image data is read from the URL of the POI display image file 223 and displayed superimposed on the map (623). If there is an adjacent POI display image file according to the display area, the URL of the POI display image file is generated in the same manner as the map image file (624), and additionally displayed (623). In this way, when displaying a thematic map with POI information superimposed, only a few POI display image files need to be transferred and displayed, and a certain level of performance is guaranteed regardless of the number of POI data. The

  Further, when displaying detailed information of POI data, the POI search unit 124 is used as a parameter by inputting arbitrary coordinates on the map, and the POI acquisition unit 113 is called to request POI data. The POI acquisition unit 113 acquires the corresponding POI data from the POI database 103 by coordinates, and passes (transmits) the acquired POI data to the POI display unit 125 for display.
