Here, the DBMS 160 includes, in particular, an artificial satellite image data search DB, an order management DB, a raw satellite image data DB, and a standard image DB. The satellite image data search DB includes a sample to search for pre-recorded satellite image data. A large number of images are stored, and the order management DB stores information necessary for providing satellite image data desired by the user, including one or more of purchase order information, shooting order information, or information related to the progress until completion of the order. The raw satellite image data DB stores the raw satellite image data received from the satellite, and the standard image DB stores the processed standard image.

Next, the search order support module 110 is connected to the satellite image data search DB stored in the form of a sample image of the pre-recorded satellite image data to provide a search screen to the user terminal in the form that the user can search the user By allowing users to search for the desired satellite image data, the user can decide whether to purchase the previously recorded satellite image data or to request a new shooting order. It is possible to input purchase order information on the captured satellite image data or shooting order information on the satellite image data to be newly photographed. At this time, detailed information of the product order and the photographing order input from the user is managed as a database, and the photographing order region information is preferably input in the form of GIS (Geographic Information System) data. If the sample image can be implemented in a low dose, the form is not limited, but may preferably be a thumbnail form.

Looking at the flow chart of the main procedure according to an embodiment performed in the search order support module 110 with reference to Figure 3, search order support module 110 receives the user's identifier and password to register the user to verify the identity And / or change (S100). The search order support module 110 processes the identification of the user and registers a new user, and then, if the user wants to search the sample image of the pre-recorded satellite image data, retrieves the sample image of the desired condition from the satellite image data DB. Search and provide the result (S110), and according to the result provides a purchase order page that allows the user to place a purchase order of the searched sample image (S121), or provides a shooting order page that allows a new shooting order (S130). In addition, when the sample image is not searched, it provides an order screen that allows a new shooting order immediately (S130).

Next, the order management module 120 includes one or more of purchase order information, shooting order information or information related to the progress until completion of the order entered through the order input screen provided by the search order support module 110 It builds an order management DB and handles the service of providing users with satellite image data suitable for their orders.

It is stored and managed in the database so that the video data requested by the user can be delivered to the user through the proper procedure. In the case of a purchase order, the purchase order is transmitted to the image processing module 140, and the standard satellite image obtained by processing the raw satellite image data of the corresponding sample image is received and provided to the user terminal. Accordingly, by evaluating whether the newly acquired image by the shooting performance support module 130 satisfies the requester's initial order condition, information on the shooting performance support module 130 is used to determine whether to additionally photograph the same region. to provide.

That is, the order management module 120 includes a sample image information registered by the user when the sample image of the new satellite image data is registered in the satellite image data search DB by the image processing module 140 including the validity evaluation means. In order to evaluate the suitability of the shooting order conditions, the validity evaluation is performed.When the validity evaluation of the image acquired according to the shooting order is compared with the shooting order conditions, additional shooting is performed, and if it is met, After confirming that all images of the requested area are secured, the sample order is delivered to the user terminal in a form in which the user can determine whether to use the service. In some cases, the image may not be perfectly matched with the order conditions, but may be implemented to determine whether the image is determined to be available to the user and determine whether it is available through user confirmation.

Looking at the flow chart of the main procedure according to an embodiment performed when receiving a photographing order in the order management module 120 with reference to Figure 4, first receiving a photographing order through the search order support module 110 (S200) photographing order The information is transmitted to the photographing possibility analysis module 150 (S210). When the photographing probability evaluation data is transmitted from the photographing possibility analyzing module 150, the user transmits the photographing possibility evaluation data to the user terminal in a form in which the user can approve, reanalyze, and cancel the order (S220). If the user approves according to whether the user approves (S230), the photographing order information is transmitted to the photographing execution support module 130 (S240), and if the user does not approve the photographing order contents depending on whether or not to change the photographing order content (S231). If you change the request to re-analyze is carried out again from S210, if you do not change the shooting order content is considered as order cancellation (S232).

Thereafter, satellite imaging is performed by the photographing execution support module 130 to receive the sample image generated by the image processing module 140 from the raw satellite image data of the new photographed image (S250). By performing the validity evaluation to determine the suitability of the received sample image against the received photographing order information (S260), if the validity of the additional shooting (S261) to pass the additional shooting order to the shooting performance support module (S240), If valid, the sample image is transmitted to the user terminal by allowing the user to confirm the use or to change the shooting conditions (S270). If the use of the sample image is not confirmed according to the user's use decision (S280), additional shooting is performed (S261), and the standard image of the sample image determined by the user generated by the image processing module 140 is used. Received and delivered to the user terminal (S290), and ends the shooting order.

The main procedure performed when the photographing order is received by the order management module 120 is as described above, but in some cases S210 to S230, S260, and S280 may be omitted.

Next, referring to the photographing possibility analysis module 150, the photographing possibility analysis module 150 analyzes the feasibility by considering the photographing orders of the newly input user together with the orders reflected in the current photographing plan. The shooting plan conditions that can be reflected can be calculated.

That is, the photographing possibility analysis module 150 inputs the user's photographing order information and the satellite operation restriction information managed by the photographing execution support module 130 transmitted through the order management module 120, and other necessary photographing possibilities. Analytical criteria will be used to assess and manage the feasibility of individual photography orders. In addition, the result of the analysis is converted into the GIS data form to be delivered to the shooting performance support module 130, so that the shooting performance support module 130 can refer to this to establish a shooting plan.

As such, the photographing possibility analysis module 150 analyzes and evaluates the photographing performance possibility of the satellite image according to the photographing order information before preparing the photographing plan, and prepares the possibility evaluation data, and the user can approve, reanalyze, or cancel the order. It is provided to the user in the form directly or through the order management module, and the possibility evaluation data approved by the user is transmitted to the satellite image recording performance support module. In order to derive a feasible alternative by adjusting the detailed conditions of the order, and to confirm the photographing order in consultation with the user, the photographing possibility analysis module 150 is an essential component of the satellite image data providing service system of the present invention. If included, the system can be operated more efficiently.

With reference to Figure 5 looks at the flow chart of the main procedure according to an embodiment performed when receiving a photographing order in the photographing probability analysis module 150. First, when a photographing order is received (S500), the expected number of images required to include all the corresponding order regions is calculated (S510). Afterwards, the total number of shots required to secure all valid images for the region is calculated (S520). Once the total number of required shots is calculated, the user can approve, re-analyze, or cancel the order by creating shooting possibility evaluation data that can be reflected in the actual satellite operation through the conflict resolution process (S530). Provided to the user terminal in the form that can be (S540). Then, if the user who requested the corresponding analysis of the analyzed photographability evaluation data is approved, the approved photographing performance evaluation data is transferred to the photographing performance support module 130 (S560). If it is changed according to the) return to S500 to re-analyze the shooting possibility, if not changed it is considered to cancel the shooting order (S552).

Next, the photographing execution support module 130 establishes a photographing plan for performing photographing orders, and performs new photographing through satellites according to the photographing plan established.

Therefore, the photographing execution support module 130 transmits the photographing planning means 131 for establishing the photographing plan, and the photographing plan to the satellite to perform new photographing, and to the data receiving means 141 of the image processing module 140. And mission planning means 132 for delivering the data receiving schedule.

Once a new photographing order is received by the photographing planning means 131, the photographing planning means 131 divides the photographing order input through the satellite orbit propagation process into an order capable of reflecting the photographing plan of the day and an order that cannot be photographed. Afterwards, orders that can be taken for optimal shooting can be selected in consideration of the detailed characteristics of individual orders such as priority, cloud forecast at the time of shooting, and shooting request period. After that, based on the photographing plan establishment guidelines negotiated through the photographing possibility analysis process for the selected photographing orders, an optimal photographing plan for each unit is established.

In this way, the photographing planning means 131 considers the photographing order and the photographing order progress information and the satellite operation restriction information only or the photographing possibility evaluation data analyzed through the photographing possibility analysis module 150 together with Establish. In particular, weather forecasting information and seasonal indicator characteristics data are constructed and applied to improve the effective image acquisition rate.
