Aboveground Forest Biomass Estimation with Landsat and LiDAR Data and Uncertainty Analysis of the Estimates
Figure 5
Aboveground forest carbon map obtained by combining forest inventory sample plot data and ETM+ images using image-based spatial co-simulation and its polynomial regression-based uncertainty analysis in Lin-An county, Zhejiang province of East China. [(a) forest carbon (T/ha) of sample plots used for development of algorithm; (b) forest carbon (T/ha) of sample plots used for test of results; (c) predicted forest carbon values (T/ha); (d) errors (T/ha) of predicted forest carbon values; (e) variance of input plot data; (f) variance of input image; (g) interaction of forest carbon and image variances; relative uncertainty contribution (%) from (h) the input plot data, (i) ETM+ image, and (j) their interaction].
