Also, the very best benefits have been obtained with photos later in the growing season (August or September) and/or when two later season pictures (August and September) were combined, or even a later season image (August or September) was combined with an earlier season image (July or June). For Hyperion, later season images when the crop canopy cover was closer to 100 and crops had been in vegetative or reproductive development stages were the top.Remote Sens. 2021, 13,13 ofFigure 6.

Also like with Hyperion, the double images yielded larger accuracies than single photos. For example, RF single image accuracies of 680 had been slightly decrease than double image accuracies of 673 . Similarly, SVM single image accuracies of 620 have been slightly lower than double image accuracies of 675 . Nevertheless, these improvements going from single to double images were substantially smaller sized with DESIS photos than with Hyperion photos. In reality, producer’s and user’s accuracies for winter wheat decreased when using double images (Table 11). On account of the distinct differences in the phenological growth stages in the crops in the June DESIS image, it yielded the highest single image accuracies instead of later inside the season. The highest double image accuracies have been most usually from making use of a single early (June) and 1 late (August) image (Tables ten and 11).Remote Sens. 2021, 13,15 ofTable 6.
