Imaging spectrometer sensors detect chemical and optical signals in the forest, revealing everything from the water content of leaves to chemicals that indicate if a plant is under stress from drought. In this image, taken near the Manu River in Peru, canopies in blue contain high nitrogen concentrations; in purple, high nitrogen, water, and cellulose content; and in red, high chlorophyll and other photosynthetic pigments. - Check out more images here.
