Table 2 Pearson correlation coefficients (r) comparing measured field-plot ground data to hyperspectral spectral mixture analysis (SMA) and multi-spectral indices dNBR and RdNBR. Bold values are significant at p < 0.05. Organic ground cover refers to green and non-photosynthetic vegetation, while inorganic refers to soil, rock and ash.
