![]() A traditional approach to spectrometry is to use several cameras with long or short bandpass filters that allow the required spectrum to pass trough while blocking the others. But multispectral cameras can be costly, and their price is directly proportional to the sort of technology they implement. ![]() If combined with a drone, the camera can provide the data for quick NDVIs (Normalised Difference Vegetation Index), create mosaics of farms, forests or woodlands, understand nitrogen consumption, create yield maps and so on. ![]() A multispectral camera can be a handy tool to detect stress in plants, or recognise different species in lieu of the differences in the reflectance signatures of plants in general.
