Hyperspectral Signatures
Detailed Description
Figure 5: The hyperspectral data of some of the major world crops gathered from different places in the world are pooled based on their growing stages and plotted. The data are in 400-2500 nm range. Crops at distinct growth stages are characterized. Subtle changes in spectral reflectivity can be seen throughout the spectral range that indicate differences in biophysical and biochemical properties as well as structural and moisture properties of crops. Spectral plots are average values takes from a large sample size shown within the brackets of each spectrum in the legend. (Thenkabail et al. 2013)
