APPLICATION CASE

Vegetation Indices

Vegetation indices can be calculated from multispectral or hyperspectral measurements. A vegetation index is calculated from the spectral reflectance of a plant sample at two or more wavelengths. Such indices serve to characterize developmental or physiological properties of the plants. For instance, greenness indices relate to chlorophyll abundance, pigment-related indices refer to e.g., anthocyanin or carotenoids, or stress-related indices are responsive to biotic and abiotic stress factors. Dozens of indices are reported in the literature, and it is possible to establish customized indices, too.
