Best descriptive linear models for 14 vegetation attributes (VA) as a function of 1, 2 and 3 textural variables (TV) with corresponding R2, P and R2CV values.

Only those textural variables that were included in at least two models are shown. For the descriptive models conventional R2 values are reported, while for the predictive models R2CV is reported, so the values are not strictly comparable (see Methods for explanation). P–values calculated from the empirical distribution of the largest expected R2. TV entries in bold typeface are the best models according to AICc when comparing, for each VA separately, models of different type. The plus (+) and minus (−) symbols denote the sign of the coefficients in the models (values reported in Table S2). See Table 1 for vegetational attributes abbreviations. IR: near infra-red band, RED: red band, NDVI: Normalized Difference Vegetation Index, EVI: Enhanced Vegetation Index. See Table 3 for the description of textural variables denoted by subindices MEAN, VAR, ASM, CORR, DR, SKEW, DISS, and CONT.
