Type of variable | Variable | Description |
---|---|---|
LiDAR | Height metrics | These metrics includes mean, median, mode, maximum and minimum of canopy height, the variations of canopy height (variance, coefficient of variation) as well as percentiles 1, 5, 10…100 and L-moments. See [49] for description and formulas. |
Point density metrics | Metrics used to evaluate canopy coverage. See [49] for description and formulas. | |
ALOS PALSAR | HH | Radar backscatter HH polarization |
HV | Radar backscatter HV polarization | |
NDBI | The normalized difference backscatter index between the HH and HV bands. [32]. | |
Texture of HH, HV and NDBI | The second-order texture measures used in this study are homogeneity (hom), contrast (cont), dissimilarity (dis), entropy (ent), angular second moment (asm), mean (mean), variance (var), and correlation (cor). See Haralick et al. [50] for details and formulas. | |
Climate | CWD | The Climatic Water Deficit (CWD), calculated as the difference between rainfall and evapotranspiration in the dry months [51]. |
