Search period, etc.), and converts the received query into a command of a form that can be analyzed and processed (302).

The child process determines whether the output command is to perform a current position search of the vehicle or cargo (303), and if the current position search of the vehicle and cargo is performed, checks whether the command outputs a search result as a string. 304.

As a result of confirming whether the command outputs the search results as a string, and outputting the search results as a string, the GPS location information (Xi) corresponding to the vehicle identifier (ID) or the cargo identifier (ID) in the location information database 26 is displayed. , Yi) is extracted (305), and the "administrative motion" object including GPS position information (Xi, Yi) is extracted from the spatial data processor 23 (306).

Extract the representative name object closest to the GPS location information (Xi, Yi) of the cargo or vehicle from the representative name (name of the main building layer used for names of major government offices, schools, banks, etc.) included in the extracted administrative building object ( In step 308, a straight line distance between the extracted representative name object and the location of the cargo or vehicle (Xi, Yi) is obtained (308).

Character string position information (eg, Korea Telecom 100M Umyeon-dong, Seocho-gu, Seoul) obtained by obtaining a straight line distance between a representative name object and a location of a cargo or a vehicle is transmitted to the user (309).

As a result of performing a current position search of the vehicle or cargo and confirming whether the command is outputting the search results as a string, if the output is not outputted as a string but output as a map, the vehicle information or the cargo is displayed in the location information DB 26. GPS location information (Xi, Yi) corresponding to the ID is extracted (310), the map output area including the location (Xi, Yi) of the cargo or vehicle from the spatial data processor 23, along the scale included in the user query The coordinates are calculated (311).

As a result of determining whether the outputted command is to search the current location of the vehicle or cargo, if the search is not the current location but the moving path search, the GPS location information set ((X1, Y1), (X2, Y2), ....... (Xm, Ym), (m is the total number of GPS data by the unique vehicle ID or cargo ID collected during the search period)) and extract (312) From the spatial data processor 25, the map output area coordinates including the GPS location information sets ((X1, Y1), (X2, Y2),... (Xm, Ym)) are calculated (313). ).

Since the user's request is to search the current location of the vehicle or cargo and output the search result on the map, the user has passed the process of calculating the map output area coordinates (311) or performing the search of the movement path of the vehicle or cargo. After the process of calculating the region coordinates 313, the layer included in the rectangular region coordinates ((Xa, Ya), (Xb, Yb)), which are calculated map output region coordinates, is searched (314).

Extract the objects in the layer included in the rectangular coordinates ((Xa, Ya), (Xb, Yb)) (315), and output the map by outputting the vector data of the extracted objects to the device device context (DC) Map information according to area coordinates is stored (316), and the GPS location information extracted in the memory DC storing map information is displayed as a symbol or a line (317).

The map data containing the location information stored in the memory DC is converted into a GIF (Graph Graphics Interchange Format) image file (318), and the resulting map image file is transmitted to the user (319).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be apparent to those of ordinary knowledge.

According to the present invention as described above, when a user selects a vehicle or a cargo to be searched while providing a cargo transportation information service on the Internet, the current position or movement path of the vehicle (or cargo) is displayed on a web page in real time. It can be printed as an image map to satisfy the user's requirements for checking cargo location and status information from the point of request to the destination, and does not require the user to install a separate vehicle control program. It is effective to get the information you want without experience.

In addition, the present invention connects a fixed number of map mappings and image converters to the spatial data processor, and then distributes the search queries received for each user at each initial user access point to each map mapping and image converter. By being handled by a child process, it is possible to provide map-related information service to an unspecified number regardless of the concurrent user limit of the spatial data processor.
