The Effect of Spatial Scale on the Prediction of Tropical Forest Attributes from Image Texture

Figure 3

Maximum goodness-of-fit value () of the best-competing models (ΔAICc ≤ 2), describing each forest attribute (top axis) as a function of one or more image metrics (left axis) using different multispectral bands (bottom axis) and window sizes (right axis). Forest attributes: basal area (BA), density (D), aboveground biomass (AGB), standard deviation of height (HSD), and mean height (H); window sizes: 5, 9, and 21 pixels; bands: red (R), near-infrared (NIR), normalised difference vegetation index (NDVI), and enhanced vegetation index (EVI). Subscripts s and t in the image metric abbreviations indicate statistical and texture metrics, respectively (see Table S1 for details).
