The geospatial technology available in the past was limited to large machinery, such as crop-dusters and other planes. This made it mandatory that a technology more apt for farmers was developed, and it came in the form of the drones or unmanned aerial vehicles (UAVs). The advantages of drones as an assistant in precision agriculture are quite plenty.
· The images taken using a drone are from a low altitude. You must know that according to FAA no unmanned aerial system can fly 120 meters or 400 feet above the ground. This makes it perfect for taking images required for agricultural purposes.
