A drone with powers far superior to those of the average eye in the sky could significantly aid farmers monitoring the health of their crops. The drone, developed by researchers at the École Polytechnique Fédérale de Lausanne (EPFL), is fitted with a camera that uses hyperspectral imaging.
This technology makes use of more colour spectrums than the human eye can see to collect information from across the electromagnetic spectrum. It can be used to find objects, identify minerals and distinguish between plant species.

Watch the video above to see how hyperspectral imaging works.
