The following describes the functions of each component.

Referring to FIG. 1, the parcel information retrieval and management system 130 of the server 100 is based on the land use status of each administrative district based on the intellectual database 160 having a topology for managing land information of the waterside zone. The distribution status of state and private lands is shown as a figure with actual geographical coordinates, and statistics on these are provided. In addition, in relation to the land purchase by the user 10, the actual purchase parcel status is identified through the transaction of the land and the land valuation management, and in the case of environmental management, the exact location of the pollutant by linking the relevant attribute of the pollutant discharge facility with the number Identify and manage the attributes of the installation. Incidentally, it will provide statistics on the status of the land, the statistics on the classification of ownership, the statistics on the status of land by classification, the status statistics on the use area, and the statistics on the usage area.

The decision support system 140 of the server 100 supports decision making for long term land management for the waterside area. To this end, an effective user interface is constructed around a GUI (Graphic User Interface), and useful information is created through various search functions and overlapping functions. For the management of the purchase parcels to be continued, the candidate region for purchase will be selected based on the comparison of the ownership of the land, the land price, the valuation of the external agency, and the desired sale amount of the owner. In addition, in case of waterfront zone boundary area, it compares the area of each parcel with that of the included area, and helps the decision maker to decide whether to buy the boundary land. In terms of environmental management, it is necessary to identify the discharge and treatment capacity of sewage discharger and to help the installation of appropriate treatment facilities for each type of industry.

The intellectual database 160 of the server 100 is composed of a figure database 162 and an attribute database 164.

Referring to FIG. 2A, the figure database 162 is based on a digital map, where the digital map converts the cadastral circle of the city / group related to the waterfront area into a vector form. In addition, the numerical index map has a polygonal phase, has the number of lands as an attribute value with the minimum number of copper and copper, and is divided and managed on the basis of the small copper. At this time, the structured digital topographic map and thematic map are used as auxiliary data in the construction of the digital map and system operation.

Referring to FIG. 2B, the attribute database 164 is associated with the figure database 162 based on administrative districts and branch numbers, and is classified into cadastral study, building account book, boundary parcel, land purchase, and the like. At this time, the cadastral study includes information such as administrative district code, category, owner, owner's address, public land price, area, etc., and the building register includes business name, location, building area, business area, representative, installation date, facility capacity, and daily average water. Information on usage, volleyball watershed, and representative emissions are included. In addition, the boundary parcel includes information such as waterfront zone designation, exclusion zone name, parcel division, internal parcel area, and external parcel area, and land purchase includes receipt number, date of receipt, desired price, appraisal agency, valuation amount, Information on the valuation date, contract date, number of copies, progress, and date of purchase are included.

Referring to FIG. 3, a waterfront zone land information management method based on a GIS is described. First, when a plurality of users 10 who want to acquire waterfront zone land information are connected to the server 100, the server controller 120 may be configured. System initialization is performed (S100).

When the system is initialized, the system initial screen is transmitted to the user 10 through the GUI 110, and the figure information and the attribute information of the figure database 162 and the attribute database 164 used in the system are loaded. S150).

When the system initialization is completed, as shown in FIG. 4, the system 10 transmits a system main screen configured to select a function-specific menu such as inquiry, parcel search, parcel management, processing facility selection, graph, and output. (S200).

This system consists of DDE (Dynamic Data Exchange) and ADO (Active Data Object), so that DDE communication is initialized at the start of the system, and connected to the database using ADO. At this time, DDE communication exchanges data between applications, so it is always connected until the shutdown of the system. In case of ADO, the connection is maintained until the shutdown of the system. You will repeat with and close. The function menu is designed to carry out the function by delivering the corresponding message through DDE.

When the user 10 selects a function-specific menu of the transmitted system main screen (S300), the property information of the parcel of the selected spatial object is inquired and provided and modified through a dialog box (S400). The figure database 162 and the attribute database 164 are connected to the ADO, and are designed to inquire or modify related attributes by using the minimum number of units of units as the identifier through the DDE.

In this case, the step of inquiring and modifying attribute information on parcels of the selected spatial object (S400) will be described in detail with reference to FIG. 5.

First, the property information of the property database 164 of the parcel unit and the figure information of the figure database 162 are connected based on the number, so that the user 10 can select parcels of the unit of the space, which is the spatial object to be inquired. It becomes (S410).

As such, when the user 10 selects the administrative region and the branch number of the spatial object, the server controller 110 codes and transmits the administrative region and the branch number to the parcel information retrieval and management system 130 through the SDE (S420). ).

The parcel information retrieval and management system 130 having received the coded administrative area and the number is transferred to the attribute database 164 using SQL (Standard Query Language) (S430), and the attribute information of the parcel is transmitted to the attribute database (S430). Extracted from 164 and is shown to the user 10 via a dialog box (S440).

At this time, the user 10 reviews the attribute information shown through the dialog box and if there is an attribute that needs to be corrected (S450), it updates the attribute information and stores it in the attribute database 164 (S460).

After the inquiry and modification of the figure information and the attribute information of the intellectual database 160 is completed through this process, the user 10 outputs the screen result of the inquiry and the modified attribute information through the printer or / and the plotter, or the title and the legend. The object is output as a drawing having a format such as the above, and the object attribute is output even in a tabular format having a fixed form (S500).

In this case, when the output result is a drawing output, the result displayed on the screen is output through a printer or / and a plotter, and in the case of a report output, it is stored as an application file using an export function.

When the result review of the inquiry and the revised attribute information is completed, the decision support system 140 determines whether the purchase parcel of the unit of the unit is selected by the user 10 (S600).

As a result of the determination, when the purchase parcel is selected by the user 10, the decision support system 140 performs a decision support procedure for the parcel purchase (S700).

In this case, as shown in FIG. 6, when the user 10 selects a target area for parcel purchase at least a unit of land, the attribute database 164 related to the parcel of the target area is selected. Land owner, land use status, area, public land, multiple polling for pollutant emissions (S710).

When the result of the attribute information of the attribute database 164 through the multiple search is displayed, the user 10 examines the result and then selects a candidate parcel to purchase (S720).

Next, the decision support system 140 performs an objective evaluation on the value of the land through the evaluation of the candidate parcel selected by the user 10 (S730).

When the appraisal for the candidate parcel selected by the user 10 is completed, the user 10 determines whether to purchase the final purchase (S740), and the decision support system 140 completes the final purchase by the user 10. If it is registered in the system (S750).

On the other hand, if the purchase parcel is not selected by the user 10 as a result of the determination, the decision support system 140 determines whether the target parcel of the unit of the unit for the purification facility management is selected from the user 10 ( S800).

As a result of determination, when the target parcels of the same unit for the purification facility management are selected from the user 10, the decision support system 140 performs a decision support procedure for the management of the purification facility (S900).

At this time, the decision support procedure for the management of the purification facility, as shown in Figure 7, when the user 10 selects the target area for the installation of the purification facilities of at least the unit, the unit (S800), attributes related to the parcel of the target area After determining the location of the sewage discharged building in the database 164, the sewage purification facility is searched for unscheduled land (S910).

Next, the user 10 grasps the amount of sewage discharged from the sewage discharge facility and the kinds of major pollutants displayed on the attribute information of the uncleaned sewage treatment facility site shown by the search result (S920).

After that, through the sewage discharge amount of the sewage discharge facility and the main contaminants, the location of the appropriate sewage purification facility is finally selected (S930), and the selected sewage purification facility is registered in the system (S940).

On the other hand, if the target parcels of the same unit for management of purification facilities are not selected by the user 10, the entire system is terminated. At this time, when the system is terminated, the application program is terminated using DDE communication, and the attribute database 164 is closed through ADO.
