The map display control unit 64 causes the color of each position of the area Qn to correspond to each rank in the first map display unit 81A after the map generation unit 65 determines the rank of each of the plurality of areas Qn. The vibration map F11 is displayed on the first map display unit 81.

Further, the map generation unit 65 extracts the other map data selected by the data selection unit 85 from the storage unit 63, and the fields in the second map display unit 81B are divided into a plurality of areas Qn (n = 1, 2, 3.・ In the data in other map data divided into n), a plurality of data Gn [i] (n: classification, Gn [i]: data, i: number of data) entering each of the divided areas Qn are averaged The average value is set to a representative value Dn (n = 1, 2, 3... N). Alternatively, the map generation unit 65 sets, as the representative value Dn, an integrated value obtained by integrating a plurality of data Gn [i] entering each of the divided areas Qn in the data in the other map data. Alternatively, the map generation unit 65 sets, as the representative value Dn, a numerical value around the area obtained by dividing the average value and the integrated value by the area of the area Qn.

  After obtaining the representative value Dn, the map generation unit 65 assigns a plurality of groups (a plurality of ranks) in accordance with the size (value) of the representative value Dn. The map display control unit 64 causes the color of each position of the area Qn to correspond to each rank in the second map display unit 81B after the map generation unit 65 obtains the rank of each of the plurality of areas Qn. Display the agriculture map F12.

The agriculture support system includes an external terminal 70 that displays the vibration map generated by the map generation unit 65 and another agriculture map different from the vibration map. Therefore, the vibration map can be easily compared with other agricultural maps. For example, it is possible to compare the relationship between the vibration value in the case of cultivating with the working device 3 and the growth map.
As shown in FIG. 1, the server 60 may include a correlation operation unit 86. The correlation operation unit 86 is composed of electrical / electronic components provided in the server 60, a program stored in the server 60, and the like. The correlation operation unit 86 calculates the correlation between the vibration map data and the other map data.

  The correlation operation unit 68 obtains a correlation coefficient between the vibration map data Gn [i] 1 and the other map data data Gn [i] 2. For example, using the vibration map data Gn [i] 1 and the other map data data Gn [i] 2, the correlation operation unit 68 calculates the correlation coefficient Cn for each area Qn (n = 1, 2, 3...・ Ask for n). For example, when the number of data in area Q1 (n = 1) is 3 (i = 3), all data of vibration map data G1 [1] 1, G1 [2] 1, G1 [3] 1 and others are The correlation coefficient with all data of map data G1 [1] 2, G1 [2] 2, G1 [3] 2 is set as the correlation coefficient C1 of the area Q1.

  Then, the correlation operation unit 68 obtains the correlation coefficient Cn (n = 1, 2, 3... N) for each area Qn, and then obtains the obtained correlation coefficient Cn as the magnitude of the correlation coefficient Cn. A correlation map F13 is created as shown in FIG. 4 by assigning a plurality of groups (a plurality of ranks) according to the value). When the correlation operation unit 68 obtains the correlation coefficient Cn for each area Qn, the map display control unit 64 displays the correlation map F13 on the third map display unit 81C of the map display screen M2.

  That is, the third map display unit 81C displays the correlation map F13 in which the color or the like is changed for each rank of each area Qn allocated by the correlation operation unit 68. That is, in the third map display unit 81C, the mesh type correlation map F13 in which the correlation coefficient Cn is assigned to the area Qn is displayed by dividing the field indicating the field etc. into a plurality. In the embodiment described above, the visualization of the correlation map F13 with a mesh map has been illustrated, but the correlation map F13 is not limited to the above-described example.

  In addition, although the correlation operation unit 68 calculates the correlation coefficient for each area Qn, instead of this, all data of the vibration map data Gn [i] 1 and the other map data data Gn [i] 2 are obtained. The correlation coefficient with all data may be calculated. In this case, the third map display unit 81C displays the correlation coefficient obtained from all the data. Therefore, the correlation operation unit 68 can easily grasp the strength of the correlation between the vibration map and the other maps. For example, in the case where the work device 3 is a tillage, if the correlation between the vibration map and the harvest map in the tillage is strong, the yield can be changed by adjusting the operation of the tillage.

It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is indicated not by the above description but by claims, and is intended to include all modifications within the meaning and scope equivalent to claims.
