recommendations! Published in 2018 at "Ecology and Evolution"

DOI: 10.1002/ece3.4229

Abstract: Abstract Extensive studies have focused on assessing leaf chlorophyll content through spectral indices; however, the accuracy is weakened by limited wavebands and coarse resolution. With hundreds of wavebands, hyperspectral data can substantially capture the essential… read more here.
