Drones make growing grapes in the California vineyards more healthy.The drones utilize invisible light taking photos using multispectral cameras. They connect those images and then the composite image is processed by a proprietary Enhanced Vegetation Index computer algorithm. This creates a colored image which makes vine vigor visible which alerts the vineyard personnel in charge to various levels of health in their vineyard. Vigor maps are like compasses. They tell them where vines are weak.
