For example, as shown in FIG. 2, the display unit 250 displays an image representing the field candidate area on a map. The display unit 250 displays, for example, an image representing the area of the registered field 400 represented by the field data stored in the field group data 300 and the work area 500 on a map. The display unit 250 may display the field candidate area in a different color, for example, so that it can be distinguished from the other work areas 500 . For example, the display unit 250 highlights the field candidate area compared to other work areas 500 . The display unit 250 may display a list of field candidate areas.

The user sets the area of the registered field 400 of the field data to be registered, and sets the attribute information about the registered field 400, such as the field name, owner name, and crop name shown in FIG. For example, first, the user inputs a selection operation to the input/output device 210 to select a work area 500 to be newly registered as agricultural field data. When the selection operation is input, the display unit 250 displays one or more candidate areas for the registered field 400 represented by the field data to be registered, based on the selected work area 500 . For example, when one of the plurality of adjacent work areas 500 is selected, the display unit 250 displays each work area 500 and the adjacent work areas 500 as candidate areas for the registered field 400. to display the integrated area. For example, when the first work area 500-1 is selected, the display unit 250 displays the first work area 500-1, the second work area 500-2, the third work area 500-3, the first work area An area obtained by integrating the three work areas 500 from 500-1 to the third work area 500-3 is displayed.
