In FIG. 4, the GIS operating environment providing unit 310 creates a virtualized database for each user by replicating the spatial information object data in the original database unit 115 and provides a GIS operating environment linked with the corresponding virtualized database (step S410). ). The GIS operating environment operation unit 330 may perform overall computerized environment and resource management of the original database unit 115 and the GIS operating environment provider 310 by a GIS-based virtualized data service operator (step S420).

FIG. 5 is a flowchart illustrating an embodiment of a process in which a GIS-based virtualized data service providing apparatus of FIG. 1 provides a GIS operating environment linked to a virtualized database to a GIS service operator.

In FIG. 5, the GIS operating environment providing unit 310 may receive a GIS service environment providing request of a GIS service operator regarding a specific spatial information object in the original database unit 115, and if the request is approved by an administrator. You can use the OpenStack API to perform the process for creating a virtualized database.

More specifically, the GIS operating environment provider 310 may perform user authentication for the corresponding GIS service operator using the keystone module of OpenStack, and if the authentication is successful, call the instance creation API through the glance module. You can create a virtualization instance based on the template image, set the storage space of the virtualization instance through the header module, register an authentication key associated with the user in the virtualization instance through the keystone module, and the Neutron module. Allows you to register an internal IP with that virtualization instance. The GIS operating environment operation unit 330 checks the creation of the virtualization instance within a specific number of times (for example, 50 times) for a specific time (for example, 10 seconds), and when the creation of the virtualization instance is confirmed to be external to the virtualization instance. You can assign an IP and terminate the process if it is not confirmed.

The GIS operation environment providing unit 310 may generate a virtualization database of the corresponding user through activation of the virtualization instance, and may generate a dump file by dumping a specific data block associated with the user request data from the original database unit 115. . When the dump file is generated, the GIS operating environment provider 310 may operate the corresponding virtualization database and then import and store the dump file. The dump file may not be generated or may be operated at a specific time (for example, 10 seconds). If you check within a certain number of times (for example, 50 times), you can terminate the process if the virtualization database is not up.

The GIS operating environment providing unit 310 creates a virtualization database through these processes and simultaneously connects to the virtualization database and includes a network IP, hardware environment, software environment, and coordinates for operating the corresponding spatial object information on a map. Create and provide a GIS operating environment that includes information datasets.

The GIS operating environment operation unit 330 may process operations required in the above processes through an API that may be called by the GIS service operator terminal 120, and provide access to the corresponding GIS operating environment to provide the corresponding GIS service operator. Can operate the corresponding spatial object information on the map. For example, the GIS operating environment operation unit 330 may run GeoServer, an open GIS service engine for geospatial space, and terminate the process if GeoServer is not running as a result of checking the status of the GeoServer within 50 times in 60 seconds. When GeoServer is running, register GeoServer on workstation, register DB store to broker GeoDB sales and purchases to GeoServer, and register the layer information of virtualization database to GeoServer. The setting of the layer information can be completed. When the setting of the GIS operating environment is completed through the above processes, the GIS operating environment operation unit 330 may request a user request data of a virtualized database (eg, SDBaaS, Secure DataBase as a Service) through the corresponding GIS operating environment without a separate procedure. GIS service operators can be made available for service development directly on the Web.

FIG. 6 is a flowchart illustrating an embodiment of a process in which a GIS-based virtualized data service providing apparatus of FIG. 1 provides access to a GIS operating environment through an API (Application Programming Interface) that may be called by a GIS service operator. to be.

In FIG. 6, the GIS operating environment operating unit 330 may operate GeoServer, an open GIS service engine, for the specific spatial information object data associated with a user request through an API that may be called by the GIS service operator terminal 120. GeoServer can provide visualization services for specific geospatial datasets (e.g., datasets for daycare centers) in the virtualization database of the GIS service operator and support the development of map services.

Although described above with reference to a preferred embodiment of the present application, those skilled in the art various modifications of the present application without departing from the spirit and scope of the invention described in the claims below And can be changed.
