Barcelona-based studio Noumena have used their collective backgrounds in design, research and education to develop a data-collecting drone that maps the environmental condition of land. Especially useful for farmers, N-E-R-O (Networking Environmental RObotics) allows them to determine crop health and to identify potential disease outbreaks. It does this by collecting data from the air, shooting the terrain below with a high-resolution camera that also captures near-infrared pictures. Images are translated into NDVI, an index that measures vegetation density and health by rendering a series of colour scaled images. Users can then differentiate between what is and isn’t plant matter, and what is and isn’t healthy.
