Figure 3. Empirical relationships derived between field-based LAI and LAD and PolSAR data

Figure 3. Empirical relationships derived between field-based LAI and LAD and PolSAR data (n=17 S. alterniflora marsh sites) produced mapping predictions of (a) LAI (density, R²=0.77) and (b) LAD (orientation, R²=0.74). A LAD of 0.5 is spherical, <0.5 more vertical and >0.5 more horizontal leaves and stems.
