[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] First, referring to Figure 1, we will explain an overview of a service (hereinafter referred to as "this service") that can be realized by an information processing system (see Figure 2 described later) to which a server according to one embodiment of the information processing device of the present invention is applied. FIG. 1 is a diagram showing an outline of the present service that can be realized by an information processing system to which a server according to an embodiment of the information processing device of the present invention is applied.

[0012] This service involves evaluating the characteristics of agricultural land from multiple perspectives, selecting appropriate priority areas, and efficiently consolidating and matching agricultural land.

[0013] Specifically, for example, Figure 1 shows Server 1, data sources that supply source data (satellite data, open data, farmland registers, sensor data, owner intention information), databases (public / private), and user interfaces (portal for local governments, portal for stakeholders, portal for landowners (farmland owners)).

[0014] The server 1 acquires source data (farmland information) and calculates multiple evaluation indexes such as the rate of abandoned farmland, road width, slope, and degree of irregularity of the farmland shape. This is achieved by a source data acquisition unit 51 and an evaluation index calculation unit 52 shown in Fig. 4, which will be described later, and the results are visualized as in the priority area identification screens shown in Figs. 6 to 9, which will be described later. Based on these multiple evaluation indices, the server 1 selects priority areas suitable for farmland consolidation from within the jurisdiction of the local government. This function is realized by a priority area selection unit 53 shown in Fig. 4, which will be described later. The server 1 collects intention information, such as information about the sale or lease of agricultural land, from landowners (farmland owners) within the selected priority districts, and classifies this intention information into "information about the intention to make public" and "information about the intention to keep private." This function is realized by the intention information acquisition unit 54 and classification unit 55 shown in FIG. 4 (described later), and is visualized on the landowner intention information display screen shown in FIG. 10 (described later). The intention information about the intention to make public is visualized as a target map created by the local government, and is displayed, for example, as shown in FIG. 16 (described later). The intention information about the intention to keep private can only be viewed by those who wish to acquire or use specific agricultural land for which a dedicated ID has been issued. These functions are realized by the public display control unit 56 and the private provision unit 57 shown in FIG. 4 (described later), and operate, for example, according to the processing flow shown in the conceptual diagram of the data public / private function in FIG. 15 (described later). The server 1 acquires desired conditions for agricultural land use from those who wish to acquire or use agricultural land, such as agricultural corporations or individual farmers, and compares the desired conditions with the intention information of the landowner to perform matching. This function is realized by the desired conditions acquisition unit 58 and the matching unit 59 shown in Fig. 4, which will be described later. When matching, public information or private intention information is used depending on the desired conditions, as shown in the use case screen for agricultural land consolidation, which will be described later, for example, in Fig. 11, which will be described later.

[0015] The user interface also provides a function for switching between multiple layers (such as abandoned farmland rate, irregularity of shape, slope, Agricultural Land Promotion Act classification, and City Planning Act classification) on a map using the layer display control unit 60 (see Fig. 4, described later). This is implemented as a checklist function for display items shown in the Ninataba screen image (see Fig. 13, described later). The pin display control unit 61 and farmer switching unit 62 (see Fig. 4, described later) also provide a function for pin-displaying farmland related to a selected farmer, which can be used on the farmland display screen for registered farmers (see Fig. 12, described later). Furthermore, the farmland combination display control unit 63 and total display control unit 64 (see Fig. 4, described later) also provide a function for combining and displaying multiple adjacent farms as a group based on a certain distance threshold (e.g., 1.5 m, 2 m, 5 m, 10 m, etc.), as shown in Fig. 14, described later.

[0016] In this way, it will contribute to resolving agricultural issues such as the increase in abandoned farmland and a shortage of farmers, and will enable more efficient farmland use and improved agricultural sustainability.

[0017] As described above, in this service, the intention information is divided into information to be made public and information to be kept private. That is, the server 1 can divide the collected intention information into information to be made public and information to be kept private. This allows appropriate management of information that can be made public and information that should be restricted for viewing.

[0018] In addition, this service can visualize and display public information on a map, and issue and provide a dedicated ID that allows limited viewing of private information. That is, the server 1 can visualize and display public information on a map as a target map created by a local government, or issue and provide a dedicated ID that allows limited viewing of private information to those who wish to acquire or use specific farmland. This makes it possible to provide appropriate information according to the level of disclosure of the information.

[0019] In this service, the evaluation index can include at least one of the following: abandoned farmland rate, road width, slope, and irregularity of the farmland shape. That is, the server 1 can calculate at least one of the following as an evaluation index showing the characteristics of the farmland: abandoned farmland rate, road width, slope, and irregularity of the farmland shape. This makes it possible to evaluate the condition and suitability of the farmland from multiple angles.

[0020] This service may be configured to display multiple layers on a map in a switchable manner. That is, the server 1 can switch between multiple layers on the map, including at least two of the following: abandoned farmland rate, irregularity of shape, slope, Agricultural Land Development Act classification, and City Planning Act classification. This allows the status of farmland to be evaluated and analyzed from various perspectives.

[0021] In this service, farmland related to the selected farmer may be displayed as pins on a map. That is, the server 1 displays farmland related to the selected farmer as pins on a map, and by switching the farmer, it is possible to switch to display farmland of a different farmer as pins. This makes it possible to visually grasp the distribution of farmland for each farmer.

[0022] This service may combine and display multiple adjacent farmlands as a group. That is, the server 1 can combine and display multiple adjacent farmlands as a group based on a set distance threshold (e.g., 1.5 m, 2 m, 5 m, 10 m, etc.), and calculate and display the total area and number of farmlands in the combined and displayed group. This makes it possible to efficiently identify areas where farmland consolidation is possible.

[0023] Next, with reference to FIG. 2, a description will be given of the configuration of an information processing system that realizes the provision of the above-described service, that is, an information processing system to which a server according to an embodiment of the information processing device of the present invention is applied.

A program read from the removable media 21 by the drive 20 is installed in the storage unit 18 as needed. Furthermore, the removable medium 21 can also store various data stored in the storage unit 18 in the same manner as the storage unit 18.

[0032] Although not shown, the local government terminal 2, agricultural corporation terminal 3, and farmland owner terminal 4 in Fig. 2 can also have basically the same hardware configuration as that shown in Fig. 3. Therefore, a description of the hardware configuration of the local government terminal 2, agricultural corporation terminal 3, and farmland owner terminal 4 will be omitted.

[0033] The various hardware and software components constituting the information processing system of FIG. 2, including the server 1 of FIG. 3, work together to execute various processes for providing the present service of FIG.

[0034] FIG. 4 is a functional block diagram showing an example of the functional configuration of the server of FIG. 3 in the information processing system of FIG.

[0037] The evaluation index calculation unit 52 analyzes the source data acquired by the source data acquisition unit 51 and calculates multiple evaluation indexes that indicate the characteristics of each of the multiple farmlands. The evaluation indexes include the rate of abandoned farmland, road width, slope, and irregularity of the farmland shape. The calculated evaluation indexes are stored in the evaluation index database 72.

[0038] The priority district selection unit 53 selects priority districts that are candidates for farmland consolidation from multiple districts within the jurisdiction based on the multiple evaluation indexes calculated by the evaluation index calculation unit 52. Information on the selected priority districts is stored in the evaluation index database 72.

[0039] The intention information acquisition unit 54 acquires intention information for sale or lease from the owners of each piece of farmland within the priority district selected by the priority district selection unit 53. The acquired intention information is stored in the landowner intention database 73.

[0040] The classification unit 55 classifies the intention information acquired by the intention information acquisition unit 54 into information inclined to disclose and information inclined to not disclose. The classified intention information is stored in the landowner intention database 73.

[0041] The public display control unit 56 executes control to visualize and display the publicly-ready information divided by the dividing unit 55 on a map as a target map by the local government.

[0042] The non-public information providing unit 57 provides the non-public information classified by the classification unit 55 to a person who wishes to acquire or use a specific piece of farmland by issuing a dedicated ID that can be viewed in a limited manner.

[0043] The desired condition acquisition unit 58 acquires desired conditions regarding the use of farmland from those who wish to acquire or use farmland. The acquired desired conditions are stored in the desired condition database 74.

[0044] The matching unit 59 matches each piece of farmland in the priority area with a person who wishes to acquire or use the farmland, based on the desired conditions acquired by the desired conditions acquisition unit 58 and the intention information acquired by the intention information acquisition unit 54 (if classified by the classification unit 55, the information is either publicly available or privately available depending on the desired conditions). The matching results are stored in a matching result database 75.

[0050] FIG. 5 is a flow diagram of a farmland matching process according to one embodiment of the present invention. As shown in Figure 5, the farmland matching process consists of five main steps.

[0051] First, the source data acquisition unit 51 acquires a plurality of source data (farmland information) such as satellite data and open data (Step 1: data collection).

[0052] Next, the evaluation index calculation unit 52 analyzes the acquired source data and calculates a plurality of evaluation indexes such as the rate of abandoned farmland, road width, slope, and irregularity of the farmland shape (Step 2: Data analysis).

[0053] The priority district selection unit 53 selects priority districts that are candidates for farmland consolidation from among a plurality of districts within the jurisdiction based on the calculated evaluation index (Step 3: priority district selection).

[0054] Next, the intention information acquisition unit 54 acquires information on the intention to sell or rent from the owners of farmland in the selected priority district (Step 4: Acquire intention information). This intention information is divided into publicly available information and privately available information by a classification unit 55. The publicly available information is made public as a target map of the local government by a public display control unit 56. On the other hand, the privately available information is provided by a private provision unit 57 only to those who wish to acquire or use specific farmland and have a dedicated ID.

[0055] Finally, the matching unit 59 matches the farmland with those who wish to acquire or use the farmland based on the desired conditions from those (agricultural corporations or companies) who wish to acquire or use the farmland acquired by the desired conditions acquisition unit 58 (Step 5: Matching execution). This will enable the characteristics of agricultural land to be evaluated from multiple angles, appropriate priority areas to be selected, and agricultural land to be consolidated and matched efficiently.

[0056] Next, functions and screen display examples of one embodiment of the present invention will be described in more detail with reference to FIGS.

[0057] FIG. 6 is a diagram showing an example of a screen for identifying priority areas. As shown in Figure 6, the layer display control unit 60 of the server 1 displays evaluation indicators such as the rate of abandoned farmland on a map. A layer selection menu using check boxes is displayed on the left side of the screen, allowing users to select multiple layers such as "rate of abandoned farmland," "ratio of broken land," "road width," "slope," "Agricultural Promotion Act classification," "City Planning Act classification," "planting possibility," and "aspect ratio." A legend corresponding to the selected layer is displayed on the right side, and color-coded farmland is shown on the map.

[0058] FIG. 7 is a diagram showing an example of a screen for identifying priority areas on which the rate of abandoned farmland is displayed. The abandoned farmland rate calculated by the evaluation index calculation unit 52 is visualized by color coding, with the higher the rate of abandoned farmland being represented by the shade of red. The legend on the right shows the abandoned farmland rate range from 0-20% to 81-100%. This provides the priority district selection unit 53 with information to use when selecting priority districts.

[0059] FIG. 8 is a diagram showing an example of a screen for identifying priority areas on which road width information is displayed. The width of the access road to each farmland calculated by the evaluation index calculation unit 52 is represented by different shades of purple. The legend on the right shows road width categories ranging from less than 3m to over 19.5m, as well as other / unknown categories. Road width is an important evaluation index that affects whether large agricultural machinery can be introduced, and is used as a basis for the priority area selection unit 53 when selecting priority areas.

[0060] FIG. 9 is a diagram showing an example of a screen for identifying priority areas on which gradient information is displayed. The slope of each piece of farmland calculated by the evaluation index calculation unit 52 is represented by different shades of blue. The legend on the right shows the slope classification from 0-20 degrees to 80-100 degrees. Slope is an important evaluation index that affects the difficulty of farming and the feasibility of mechanization, and is used by the priority area selection unit 53 when selecting priority areas.

[0061] FIG. 10 is a diagram showing an example of a screen displaying information on the intentions of the farmland owner. As shown in Figure 10, the intention information of the farmland owner acquired by the intention information acquisition unit 54 is visualized by color coding. The legend on the right shows the intention classification such as "want to rent," "want to sell," "already rented and will continue," "will cultivate the land myself," "private," and "unspecified." The classification unit 55 classifies this intention information into public and private and stores it in the landowner intention database 73.

[0062] FIG. 11 is a diagram illustrating an example of a use case screen for farmland consolidation. As shown in Figure 11, many small farms are displayed in different colors. On the right side of Figure 11, there is an explanation that "Small farms do not match well in one-to-one transactions, but if multiple farms are combined into one-to-one matches, the possibility of companies and large agricultural corporations entering the market increases." This shows the effect of the farmland combination display by the farmland combination display control unit 63 and the aggregate display by the aggregate display control unit 64.

[0063] FIG. 12 is a diagram showing an example of a screen displaying the farmland of a registered farmer. As shown in Figure 12, the pin display control unit 61 displays the farmland related to the selected farmer on the map with a red pin. In the "List of Farmers" at the bottom right of the screen, the farmer "Tanaka" is selected, and the farmland area (13,071.00 m) is displayed. 2 ) and the number of farms (14). The farmer switching unit 62 can switch the pins displayed by selecting another farmer from this list.

[0064] FIG. 13 shows the entire screen image of this system. As shown in Fig. 13, the screen is composed of areas for multiple functional elements, such as a checklist of display items, a function to narrow down the displayed items, a cluster display function, a function to display the total area of ​​selected farmland, and a function to display the farmland of the selected farmer. These functions are realized by the functional blocks shown in Fig. 4.

[0065] FIG. 14 is a diagram showing other functions of the present system. In FIG. 14, the cluster display function, the total area display function, and the combined field display function are explained. In particular, with the field combination display function, the farmland combination display control unit 63 combines and displays multiple adjacent farmlands as a group based on a set distance threshold (1.5 m, 2 m, 5 m, 10 m, etc.), and the total display control unit 64 calculates and displays the total area and number of farmlands in the combined and displayed group. This allows the user to visually grasp the potential for farmland consolidation.

[0066] FIG. 15 is a diagram showing the concept of the data disclosure / non-disclosure function. As shown in Figure 15, when updating data on the application, it can be divided into a route of "publicizing on the Internet" and a route of "privately soliciting agricultural corporations, etc." This corresponds to the function of the classification unit 55, and information is provided in different forms by the public display control unit 56 and the private provision unit 57.

[0067] FIG. 16 is a diagram showing an example of a target map created by a local government. As shown in Fig. 16, the public display control unit 56 visualizes and displays the publicly-ready information as a target map created by the local government. In this example, classifications such as farmer A, farmer B, farmer C, and farmed land are color-coded, and the map is used as a reference for regional planning. This target map is made public on the local government's website and is widely used as basic information for promoting agriculture.

[0068] As described above, the information processing system to which the present invention is applied can support the consolidation and efficient use of farmland through the selection of priority areas based on multiple evaluation indicators, the acquisition and classification of information on owners' intentions, the management of public and private information, and matching functions.

[0069] Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope of achieving the object of the present invention are considered to be included in the present invention.

[0070] Furthermore, the system configuration shown in FIG. 2 and the hardware configuration of the server 1 shown in FIG. 3 are merely examples for achieving the object of the present invention, and are not particularly limited.

[0071] Furthermore, the functional block diagram shown in Fig. 4 is merely an example and is not particularly limited. That is, it is sufficient if the information processing system in Fig. 2 is provided with functions that can execute the various processes described above as a whole, and the functional blocks and databases used to realize these functions are not particularly limited to the example in Fig. 4.

[0072] Furthermore, the locations of the functional blocks and databases are not limited to those shown in FIG. 4 and may be arbitrary. For example, at least some of the functional blocks and databases arranged on the server 1 side may be provided on the local government terminal 2 side, the agricultural corporation terminal 3 side, or the farmland owner terminal 4 side.

[0073] The above-described series of processes can be executed by hardware or software. Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination thereof.

[0074] When a series of processes is executed by software, the programs that make up the software are installed into a computer or the like from a network or a recording medium. The computer may be a computer built on dedicated hardware. The computer may also be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smartphone, or a personal computer.

[0075] The recording medium containing such a program may be composed not only of a removable medium (not shown) that is distributed separately from the device main body in order to provide the program to the user, but also of a recording medium that is provided to the user in a state that is pre-installed in the device main body.

[0076] In this specification, the steps describing the program to be recorded on the recording medium include not only processes that are performed in chronological order, but also processes that are not necessarily performed in chronological order but are performed in parallel or individually.

[0077] To sum up, the information processing device to which the present invention is applied is sufficient as long as it has the following configuration, and can take on a variety of different embodiments.
