Step S580, S590: When the request for the search for the national spatial information of the national spatial information requester includes the coordinate transformation in the user request, the national spatial information integrated search unit 250 requests the national spatial information conversion unit 260 to request the coordinate transformation. In operation S580, the national land space information conversion unit 260 converts the coordinates according to the coordinate conversion rule and returns the result thereof to the national spatial information integrated search unit 250 (S590).

Steps S600 and S610: If the user request includes a format conversion, the national spatial information integrated search unit 250 requests the national spatial information conversion unit 260 to convert the format (S600), and the national spatial information conversion unit ( 260 converts the format according to the format conversion rule and returns the result thereof to the national geospatial information integrated search unit 250 (S610).

Steps S620 and S630: The national spatial information integrated search unit 250 requests the national spatial spatial information conversion unit 260 to convert the GML in the OGC standard form, and the national spatial spatial information conversion unit 260 converts the integrated data into GML data. The conversion is made (S630).

Steps S640 and S650: the national spatial information integrated search unit 250 delivers all the customized user-defined national spatial information GML data to the user request processing module 241 (S640), and the user request processing module 241 The user-customized national spatial information GML data is delivered to the national spatial information requester (S650).

Through the above process, the user-customized land space information is generated according to the request for land space information, and is provided to the requester of land space information.

8 is a flowchart illustrating a process of providing a service for providing a user-customized landspace information to a client through a landspace information distribution server according to an embodiment of the present invention.

Steps S710 and S720: First, the client 600 accesses the national land information distribution server 300 and requests member authentication through login (S710), and the national land information distribution server 300 is a member through checking user information. Authentication is performed (S720).

Step S730: The client 600, which has performed member authentication, uses the map search means provided by the map search module 341 provided in the distribution service processor 340 of the national land information distribution server 300, and drags and mouses the area. By requesting the request for searching the national spatial information.

Steps S740, S750, S760, and S770: In response to a request for retrieving the national spatial information from the client 600, the map search module 341 according to the request for retrieving the national spatial information to the catalog service processor 350 through the catalog linkage module 342. The query is requested (S740), the response processor 351 of the catalog service processor 350 receiving the query request receives the request data, analyzes the query type, and transmits the query to the query analyzer 352 (S750). The analyzer 352 generates a data query according to the requested query analysis and transmits the data query to the query processor 353 (S760). The query processor 353 processes the query and transmits the query processing result to the response processor 351. It transmits (S770). In the process of processing the query by the query processor 353, the query processor 352 accesses the database 360 through the DB connection manager 354 and refers to metadata information registered for the catalog service.

Step S780: The response processor 351 that receives the query processing result from the query processor 353 transmits the query processing result to the catalog linkage module 342 of the distribution service processor 340, and the catalog linkage module 342 queries the query. After the web interface is generated, the processing result is transmitted to the client 600 so that the client 600 can check the processing result.

Steps S790 and S800: The client 600 confirming the query processing result according to the request for the land space information makes a purchase request for the desired land space information among the search results (S790), and the area of the land space information according to the purchase request. When the billing is charged according to the number of layers of the map and the payment is made by the client 600, the payment information and the purchase information are registered in the database 360 (S800).

Step S810, S820: the payment processing of the client 600 is completed, the distribution service processing unit 340 requests the data content of the national territory information area requested by the client 600 through the query to the national territory information integrated server 200 (S810), the national land spatial information integration server 200 responds by transmitting the user-customized national land spatial information content, which is a query result generated by performing a search, to the national land spatial information distribution server 300 in the form of GML (S820). ).

Steps S830 and S840: The distribution service processor 340, which receives the GML-type user-customized land-spatial information from the national land-spatial information integrated server 200, parses the received GML-type user-customized land-spatial information data to the SHP file. The client 600 moves to the link page so that the client 600 can download it (S830), and the client 600 moves to the link page and downloads the user-customized homeland spatial information data in the form of SHP to receive the service.

As such, when the client 600 accesses the national land space information distribution server 300 and requests the national land space information search, the national land space information distribution server 300 requests the national land space information request from the client 600 through a catalog service. When the client 600 pays for the purchase, the client 600 requests and provides the national land space information requested by the client 600 to the national land space information integrated server 200 and receives the provided information. Will be provided).
