Most entry level drones are easy to fly and can be productive with minimal training or technical understanding. However more and more, hardware and software innovations and miniaturization of is offering greater capability than just photography. Special camera systems such as multispectral and infrared devices are entering the market at lower prices. Advanced mapping systems such as Lidar and high accuracy GPS are also becoming adaptable to farm use. Larger drones are often required for some of this equipment as the payloads are larger. One area very familiar to the farm community is pest and disease management with aerial spraying. Larger higher powered UAV devices can distribute tanks of chemical spray or even be used for aerial seeding.

Some newer implementations are using the drone as the targeting and mapping device while ground based autonomous vehicles with advanced AI systems apply the chemical to a very specific area. This type of weed management helps reduce waste while minimising the risk of contamination across paddocks through drift.
