WebNDRE: Normalized Difference Red Edge Index. Normalized difference red edge index (NDRE for short) is a method of measuring the amount of chlorophyll in the plants. The best timing to apply NDRE is mid-to-late growing season when the plants are mature and ready to be harvested. At this point, other indices would be less effective to use. WebDescription. indices = spectralIndices (hcube) computes the greenness indices: enhanced vegetation index (EVI), modified chlorophyll absorption ratio index (MCARI), and simple ratio (SR) index of a hyperspectral data. The function reads the data cube and the wavelength values stored in the hypercube object hcube to compute the greenness indices.
