Agricultural Drones are capable of providing farmers with detailed aerial views. From irrigation problems to soil variations that aren't easily noted at ground level. Airborne cameras can also can take multispectul images, gathering data from infrared in addition to the visual spectrum. 

A drone can also survey a crop every week, every day, or any other time interval. This creates a time-series animation, showing changes in the crop, reveling areas of the crap that might be under performing compared to better yielding areas.

"Relatively cheap drones with advanced sensors and imaging capabilities are giving farmers new ways to increase yields and reduce crop damage".
