UAVs may be used for delivering parcels and all types of goods to rural areas, as well as within urban areas. Last-mile deliveries using UAVs allow delivery times to be reduced while also relieving traffic congestion in densely populated cities. Rural areas benefit as they become instantly accessible and connected. UAVs can also be used in agriculture for crop planting and spraying or to deliver medical supplies where the delivery is over a large area that is otherwise difficult to reach.
