PROBLEM TO BE SOLVED: To provide a vegetation determination program which suppresses an influence of the time of the year when an image was captured.SOLUTION: A vegetation determination program controls a computer to execute processing of: for each of a plurality of divisions which are acquired by dividing respective two images of a predetermined area captured in different periods, determining types of plants captured in the division on the basis of feature quantity of the image of the division; when plant types cannot be determined for the division included in the first image and plant types are determined for the division included in the second image, on the basis of plant information indicating feature quantity of an image of each plant captured in each time of the year, estimating feature quantity representing a state of the plant, that is indicated by a determination result for the division of the second image, in the time of the year when the first image was captured; when there is a similarity between the estimated feature quantity and the feature quantity of the corresponding division in the first image, determining that vegetation at the corresponding point has not changed between periods when the respective images were captured; and when there is no similarity, determining that the vegetation at the corresponding point has changed between periods when the respective images were captured. |
