Estimating Leaf and Canopy Biochemistry Variables in Mediterranean Holm OAK (Quercus ILEX) from Proximal and Airborne Hyperspectral Data

摘要

The study explores the use of high spatial and spectral resolution data acquired with a field spectroradiometer and an hyperspectral airborne sensor for the estimation of biochemical variables (nitrogen, carbon, LMA, water and pigment content) in the Quercus ilex strata of a wooded savanna (dehesa) ecosystem. Empirical models have been used to relate biochemical variables measured at the leaf level with spectral vegetation indices calculated from leaf and canopy spectra.
