Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing the configuration of a geographic information service system according to an embodiment of the present invention.

Referring to FIG. 1, a geographic information service system according to the present embodiment includes a Geographic Information System (GIS) client 110, a plurality of GIS servers 120-1 and 120-2, and a facility management server 150. Each of the plurality of GIS servers 120-1 and 120-2 includes spatial middleware 130-1 and 130-2 and a database 140-1 and 140-2. 150 also has a database 160.

Facility management server 150 is a server for managing the property information of the management target facilities provided by the web service using geographic information, the web service is a variety of services for the implementation of U-CITY, for example, street lamp control, underground buried water pipe It means web services such as management, traffic information management, local pollution control, and reliable zone service.

The facility management server 150 may receive state information of facilities for each service from equipment such as a sensor installed in each facility, and perform an event processing algorithm using the received state information. In the database 160 provided in the facility management server 150, attribute information of such service management target facilities, for example, installation date, equipment serial number, log record, and the like, is stored, and also status information of the facility is stored.

When the facility management server 150 receives a request for information on specific facilities from a user through a GIS screen output by the GIS viewer 117, the facility management server 150 searches for relevant information in the database 160 and the GIS viewer 117. To be displayed on the GIS screen.

The plurality of GIS servers 120-1 and 120-2 may provide spatial data of geographic information to the GIS client 110 through a communication network as data in a vector or raster form to be used on the Internet. Servers are heterogeneous servers from different manufacturers that support the GIS data transfer protocol of the Open Geospatial Consortium (OGC), an international GIS standard.

These multiple GIS servers 120-1 and 120-2 are international GIS which is an XML grammar created by an XML schema for representing geographic information composed of points, lines, planes, etc. in addition to the purpose of simple data exchange or sharing. It supports the Geography Markup Language (GML) developed by the standard Open Geospatial Consortium (OGC).

In addition, each of the plurality of GIS servers 120-1 and 120-2 is a Web Map Service (WMS), a Web Feature Service (WFS), and a GIS data transmission protocol proposed by the Open Geospatial Consortium (OGC), an international GIS standard. At least one of the Web Catalog Service (WCS) supports and transmits and receives spatial data with the GIS client 110.

When the plurality of GIS servers 120-1 and 120-2 receive a registration request for a specific service received from the GIS client 110, the plurality of GIS servers 120-1 and 120-2 issue a service code for the specific service and register the service code. Send to the GIS client 110. Therefore, when providing web services such as street light control, underground buried water pipe management, traffic information management, pollution control of local streams, and relief zone services, such as various GIS services for implementing U-CITY, a service code is issued for each service. do.

In addition, the plurality of GIS servers 120-1 and 120-2 may receive geographic information of facilities to be managed for a specific service from the GIS client 110, generate a layer of corresponding facilities, and generate a database 140-1. 140-2). Here, the geographic information of the facilities includes installation location coordinates, IDs, icons, styles, etc. of the facilities. Layers of these facilities are mapped to a map and provided to the GIS client 110.

The spatial middleware 130-1 and 130-2 inputs spatial data of geographic information received from the plurality of GIS servers 120-1 and 120-2 to the database 140-1 and 140-2, or multiple data. Extracts spatial data of geographic information from the databases 140-1 and 140-2 according to a request of the GIS servers 120-1 and 120-2 of the plurality of GIS servers 120-1 and 120-2. to provide. Typically, such spatial middleware 130-1 and 130-2 are referred to as a spatial engine.

The databases 140-1 and 140-2 are storage means for inputting / outputting spatial data at the request of the spatial middleware 130-1 and 130-2, and are typically implemented in the form of a relational database.

The GIS client 110 is a program for developing a GIS web service and providing the developed GIS web service in association with the plurality of GIS servers 120-1 and 120-2, as shown in FIG. 1. An application 111, a component module 113, a web service development module 115, and a GIS viewer 117.

The GIS application 111 is a GIS application that provides the geographic information to the GIS viewer 117. The GIS application 111 uses the GIS server 120- as spatial data of the geographic information processed by the GIS servers 120-1 and 120-2. 1, 120-2, and parses the received spatial data in the form of GML and displays it in the GIS viewer 117. In addition, when the GIS application 111 generates an event for processing specific data (map movement, feature editing, map reduction / enlargement, address search, etc.) by the user on the GIS viewer 117, the GIS application 120 requests a request accordingly. 1, 120-2).

The GIS application 111 is a pure JavaScript library developed to display geographic information, provides an API supporting GML data, and provides a GIS for spatial data access proposed by the Open Geospatial Consortium (OGC), an international GIS standard. It provides data transfer protocols, Web Map Service (WMS), Web Feature Service (WFS), and Web Catalog Service (WCS). The GIS application 111 may be an open source application, and typically may be OpenLayers or OpenScales. The API provided by the GIS application 111 may also be an open API.

The API is a basic function API that transmits and receives spatial data through GML and renders or controls a screen, and a plurality of functions are defined in each function object. These APIs consist of one js file for each object, and many functions are contained within the js file.

The GIS application 111 includes Web Map Service (WMS), Web Feature Service (WFS), and Web Catalog Service (WCS), which are GIS data transfer protocols for spatial data access proposed by the Open Geospatial Consortium (OGC), an international GIS standard. By being mounted, the GIS client 110 may provide a GIS service independently of a type of the GIS server 120-1 or 120-2 conforming to the OGC standard.

The component module 113 includes application components in which components of the map information for each web service, event processing, spatial data query operation, and spatial data control are standardized and functionalized. Here, the web service is a variety of services for implementing U-CITY. For example, the web service refers to a service such as street light control, underground buried water pipe management, traffic information management, and pollution control of a river. GIS service developers can easily select and customize these application components to implement the desired GIS service without the knowledge of GIS technology and internal mechanisms.

Application components provided by the component module 113 may be APIs, and examples of application components which are such APIs are shown in Table 1 below.

MapObj The base objects that make up the map MapSearch Object responsible for retrieving location information and spatial operations on the map MapEvent Objects responsible for handling, presenting, and controlling custom events Mapedit Object responsible for editing geographic information MapLegend Object responsible for displaying and controlling layer and legend information MapUserSpot Object responsible for managing user points of interest EquipInfoObject Object responsible for feature search, location lookup, and display Maputil The object providing the map add-on

The application component provided by the component module 113 wraps the API provided by the GIS application 111, for example, an open API supporting GML data once more, and is provided by the GIS application 111 in another expression. It can be understood as an extension of API functions.

For example, in the GIS application 111, there is a class constituting a map called 'MAP', but the 'MAP' class supports only a portion of a transaction for requesting and receiving map data in a GML format, but accumulates maps, map sizes, and various controls. It does not support specific web service functions such as button placement. Such a map, i.e., a map (MAP), is declared, and the accumulation of the map, the size of the map, the location of the map control bar, the map layer object (numeric map or aerial map), etc. The function is inherited and defined in the 'MapObj' component of Table 1 above. Accordingly, the developer may configure the map of a desired form by selecting the 'MapObj' component of the component module 113 and editing only specific parameters such as modification, addition, and deletion.

An example of a function constituting the 'MapObj' component is shown in Table 2 below.

Each application component of the component module 113 conforms to the OGC standard but supports all of the plurality of GIS servers 120-1 and 120-2 having different access URLs and different spatial data processing methods. It is written in a structure that allows branching of important processes according to models.

That is, for each application component, server type information is set such that a process specialized for each of the plurality of GIS servers 120-1 and 120-2 is branched, and corresponding server-specific functions are defined according to the set server type information. . Examples of specialized functions include functions related to access URL of a map data request target server, functions related to spatial data request method (GML elemnet), and functions related to spatial data processing method. Therefore, a developer can develop a service that can be provided with a service by accessing the desired GIS servers 120-1 and 120-2 by simply modifying server type information.

The application component provided by the component module 113 has a structure independent of service contents by providing a source and a screen in an embedded form. This enables service-independent GIS services, simplifies the process and reduces the source for GIS service development by eliminating the possibility of backreferences. An example of embedding of a source and a screen is as follows, and FIG. 5 is an example of a display screen using such an application component.

-Embedded map screen

<iframe src = "/ sga / getMap.do? serviceDomain = DTA_EDIT & serviceLayers = UCL_TOPER…> </ iframe>

Referring to FIG. 5, a road section editing interface screen of a map and a traffic information service is displayed only by invoking the application component.

The web service development module 115 is a tool that allows a developer to develop a service application for a web GIS service using the component module 113. As described above, in the web service development module 115, a developer may select an application component to provide a desired service function in the component module 113, and edit, add, or delete only specific parameters of the selected component. You can develop web service application with desired GIS service function.

The service application may be developed in the form of Java, plug-in, ActiveX, and the like. The service application developed as described above operates in dependence on the GIS viewer 117. Although a web application is described as an example of a service application in the present embodiment, a service application of various protocols may be developed without being limited thereto.

In developing a service application, the web service development module 115 first requests a service registration to the GIS servers 120-1 and 120-2, receives a service code for the service requested for registration, and receives the issued service code. Using services to distinguish between services and inserting application components for multiple services.

The GIS viewer 117 uses the service application developed through the web service development module 115, specifically, an application component included in the service application, to request the map data and query the spatial data from the GIS application 111. And the like, and outputs spatial data parsed by the GIS application 111 to the screen. The GIS viewer 117 may be a web browser including the service application.

The user can select various web services (eg, street light control, underground buried water pipe management) from the geographic information display interface provided through the GIS viewer 117, search for spatial objects, process specific event information, and the like. Can be done.

The WMS (Web Map Service) module 211 is a module that can access spatial data of geographic information by communicating with GIS servers 120-1 and 120-2. The WMS module 211 is a map for describing geographic information as a digital image file. The maps defined and generated via WMS are not only PNG, GIF, JPEG but also SVG or web computer graphic formats, which are sometimes vector graphics. API methods of the WMS module 211 may include GetCapabilities, GetMap, and GetFeatureInfo.

The WFS (Web Feature Service) module 212 is also a module that can communicate with GIS servers 120-1 and 120-2 to access spatial data of geographic information, and can access and manipulate geographical feature data. Let's do it. WMS module 211 can only receive images for maps, while WFS module 212 can receive real spatial data about geographic features such as lines, points, polygons, and create / modify / delete features. It is also possible to import or query features, locks and spatial data. API methods of the WFS module 212 may be, for example, GetCapabilities, DescribeFeatureType, GetFeature, GetGmlObject, Transcation, and LockFeature.

WCS (Web Catalog Service) module 213 is also a module that can access spatial data of geographic information by communicating with GIS servers 120-1 and 120-2, and is an interface for satellite image map service of GeoTIFF and DTED type. To provide.

API module 214 includes an API that supports data in GML form as a pure JavaScript library. Such an API may be a public open API conforming to the Open Geospatial Consortium (OGC) standard. The API module 214 receives a function of a specific API for processing spatial data from the event processing module 216 and receives a function parameter from the event processing module 216 and receives the function of the specific API called. The data is requested to the GIS servers 120-1 and 120-2 through at least one of the WMS module 211, the WFS module 212, and the WCS module 213 using the specified parameters.

The parser 215 receives the GML type spatial data from the WMS module 211, the WFS module 212, and the WCS module 213, parses the received GML type spatial data, and parses the received GML type spatial data. 117).

The event processing module 216, when a user's event on the geographic information output from the GIS viewer 117, for example, a user's event such as moving the map, searching for an address, and editing a point of interest, occurs, Receives a function call request of an API and a parameter of a called function from a service application dependent on the GIS viewer 117, and transmits a function call of the requested API and a parameter of the called function to an API module 214. . As described above, the service application includes an application component that inherits a function of the API, and the user event is followed by a function call of the API through the application component.

3 is a diagram illustrating the configuration of the GIS viewer of FIG. 1. Referring to FIG. 3, the GIS viewer 117 according to the present embodiment includes a geographic information management unit 310, an attribute information management unit 330, and a caller 350. ).

The geographic information management unit 310 provides a map management function for each service such as a map request for each service, a map output, a map movement, a feature editing, a layer management, and an address search in the GIS viewer 117, The user's request is transferred to the caller 350. The service here is a variety of services for the implementation of U-CITY, for example, street lighting control, underground buried water pipe management, traffic information management, sedimentary pollution and other services.

The attribute information management unit 330 manages attribute information of service-specific objects, such as streetlights and water pipes, which are managed for each service mapped to a map. In this case, the attribute information is data such as a facility to be managed, that is, an installation location of an object for each service, a maintenance history, and a failure history.

When the icon of the service-specific object displayed on the map is selected by the user, and the property information input request is received, the property information manager 330 transmits the ID of the selected service-specific object to the calling unit 350 and requests the related detailed information. Then, detailed information of the corresponding object for each service received is mapped and displayed in a popup form or a map.

The caller 350 is made by using an application component included in the component module 113, and a function of an application component corresponding to a user's request transmitted from the geographic information managing unit 310 or the attribute information managing unit 330. Call and the function of the called application component performs the corresponding function.

Specifically, the function of the application component called according to the user request transmitted from the geographic information management unit 310 requests related processing to the GIS servers 120-1 and 120-2 through the GIS application 111, and the attribute information. The function of the application component called according to the user request transmitted from the management unit 330 requests related processing to the facility management server 150 without passing through the GIS application 111.

As described in the present embodiment, in the geographic information service system according to the present invention, the geographic information is managed by providing the attribute information of the facilities to be managed by each service with the geographic information (map, coordinates, style, etc.) in dual form. Independence This provides scalability of geographic information and improves maintenance efficiency. Such dualization of geographic information and attribute information is achieved by dualizing the structure of an application component into a processing portion for geographic information and a processing portion for attribute information.
