The Effect of Spatial Scale on the Prediction of Tropical Forest Attributes from Image Texture
Table 2
Best-supported models describing each forest attribute as a function of one or more image metrics using different multispectral bands and window sizes.
Forest attributes: basal area (BA), density (D), aboveground biomass (AGB), standard deviation of height (HSD), and mean height (H). Bands: red (R), near-infrared (NIR), normalised difference vegetation index (NDVI), and enhanced vegetation index (EVI). poly()1 and poly()2 are the first and second terms, respectively, of a quadratic orthogonal polynomial as produced by the poly() function in R. Image metric abbreviations are described in Table S1.
