Drones provide an important innovation in vegetation monitoring in agriculture and flora and fauna research such as counting certain animal species in nature reserves.
Drone crop monitoring
By attaching a multispectral of hyperspectral NIR (near infrared) camera to a drone it is possible to map the weak spots or diseases such as mould in the vegetation, and monitor them over a period of time. Soil quality, composition and humidity can be mapped from a drone as well.
Farmers make more and more use of drone technologies to monitor the health of their crops, allowing the use of pesticides to be more targeted and less frequent. This way, both costs and and pollution of the environment (soil and groundwater) can be reduced.
Advantages
Unlike satelite images, drones are able to make detailed maps of relatively smaller areas.
Much lower costs compared to manned flights.
Less environmental pollution due to more targeted use of pesticides.
