Abstract :
In this paper, spectral derivatives and textural indices derived from a SPOT-5 image have been investigated for the potential of estimating aboveground biomass (AGB) in the region of Liangshui (47 10´N, 128 53´E), Heilongjiang Provence, China. The results indicated that textural indices were more accurate than spectral derivatives and the best model could be obtained by combining textural indices and spectral derivatives (R2=0.77 and RMSE=55.96 t/ha).
