- FIG. 4A shows an example of screen D1 displayed by the display control unit 218 (described later) on the display device of the user terminal 100 when adjusting the area of the field.
- the display area R1 in FIG. 4A is a map display area, and the map shows the field and areas into which the field is divided into arbitrary sizes.
- the moisture content of the soil in each area is represented by different shades of color, like a heat map, but the display form of screen D1 is not limited to this.
- the user can adjust the area in the field from which information about the field is to be obtained by selecting a specific area in the display area R1 as the target area.
- a specific area in the display area R1 As the example of FIG. 4A, four areas are selected as the target areas.

- the adjustment unit 212 may also adjust the size of the target area according to the information about the field to be displayed. For example, when the information about the field to be displayed is the hours of sunshine, it is important to look at the field broadly and identify areas with long and short hours of sunshine, whereas when the information about the field to be displayed is the moisture content of the soil, a perspective is required to specifically identify the crops to be irrigated.

- the adjustment unit 212 may adjust the area based on information about multiple objectives of the agricultural work to be performed, based on the smallest unit for the multiple objectives. For example, consider a case where information about a field is obtained from a soil sensor to determine whether the agricultural work "fertilization" or "irrigation" is required for the field. In this case, for example, it is determined that fertilization is required when the electrical conductivity (EC) of the soil is low, and that irrigation is required when the moisture content of the soil is low. In such a case, the area is adjusted to the extent necessary to determine whether fertilization is required, and is also adjusted to the extent necessary to determine whether irrigation is required.

- the fields displayed on screen D2 may have the same owner or different owners. This makes it possible to grasp the progress of agricultural work between fields and sales forecasts.
- material and human resources that can be provided or material and human resources that are required may be displayed as "resources". This enables efficient sharing of resources between fields.
- the adjustment unit 212 may adjust the time interval when the acquisition unit 213 acquires information about the field from the database or from the measuring device 300, and the frequency of such acquisition.

- screen D1 may have a slider O4 that sets the time of information output by adjustment unit 212.
- the current soil moisture information displayed in display area R1 or R2 can be changed to past soil moisture information, such as one day ago or one week ago.
- future soil moisture information can be output based on past and current soil moisture information using an arbitrary model, it may be possible to control the display of future soil moisture information by operating slider O4.

- the generating unit 214 may generate information about the entire field or a part of the field using information acquired by the acquiring unit 213, information evaluated by the evaluating unit 215, information determined by the work determining unit 216, etc.
- the information generated by the generating unit 214 is transmitted to the user terminal 100 by the display control unit 218 (described later) via the transmitting/receiving unit 211. As a result, screens such as those shown in Figures 4A to 4C are displayed on the display device of the user terminal 100.
- the generation unit 214 may supplement the information about the farm field in that area by estimation.

For example, the sensing device management unit 219 may manage whether sensing devices such as the measuring device 300 are operating normally, or manage the operating time of the measuring device 300. At this time, if an abnormality is detected, such as a communication error or an alarm being sounded, the sensing device management unit 219 may display this on the display unit of the input/output interface 230.
- Fig. 3A shows a flowchart of a process of outputting requested information at a desired resolution from a database that records information about the field in the field in response to a user's operation by the smart agriculture system of this embodiment
- Fig. 3B shows a sequence diagram showing an example of a process of measuring the inside of the field at a desired resolution and constructing a database by the smart agriculture system of this embodiment.
- step A01 in response to a user's operation on the terminal 100, the adjustment unit 212 of the server 200 adjusts the area in the field from which information about the field is to be acquired.

Specifically, when the user taps the "soil moisture content” button O3, the adjustment unit 212 may adjust the area with a resolution suitable for displaying the soil moisture content, and a map or the like may be displayed in the display area R1 with this as initial information. Also, when the user taps the "soil nutritional level” button O3, the adjustment unit 212 may adjust the area with a resolution suitable for displaying the soil nutritional level, and a map or the like may be displayed in the display area R1 with this as initial information. At this time, the size of the initial area may differ depending on the information about the crop, such as "soil moisture content” or "soil nutritional level” selected by the button O3.
- the user may drag the R1 map to specify the target area, or tap the O2 button or O1 button to expand or narrow the area of the target area or each area to be displayed, and at that time, the adjustment unit 212 may obtain information on the area specified by the user.

- step B08 the work instruction unit 217 of the server 200 transmits information regarding the determined content of the agricultural work to the work device 400.
- ground conditions of the field are suitable for traveling with the work implement 400.
- the larger the area of the field the more difficult it is for the human eye to grasp the ground conditions of the entire field or part of it, so it is desirable to automate this process.

- the acquisition unit 213 may detect whether there are obstacles or weeds on the ridges, and the evaluation unit 215 may evaluate the road surface condition from the number of detection points.
- the acquisition unit 213 may also measure the amount of relative change from inertial sensors such as acceleration and angular velocity, and the evaluation unit 215 may measure the unevenness or muddiness of the ground from these values. If the unevenness or muddiness is severe, the inertial sensor values will vary greatly, making it possible to measure the unevenness or muddiness of the ground.
- the evaluation unit 215 may classify objects reflected in image data acquired by the image sensor into crops, obstacles, weeds, etc. by object recognition.
- the adjustment unit 212 may adjust the area in relatively large sections in terms of performing fertilization work, irrigation work, etc.
