WDRVIWide Dynamic Range Vegetation Index

Vegetation

Formula

(alpha * N - R) / (alpha * N + R)

No radar polarizations are used in this index.

alpha

Weighting coefficient.

Default value0.1

Suggested range0.10.2

Suggested values

Aggressive correction, high LAI. Underperforms in sparse vegetation: 0.05
Conservative correction, high-biomass sensitivity without strongly down-weighting NIR: 0.2
Equal WDRVI to NDVI: 1.0
Stronger correction, moderate-to-high LAI, vegetation fraction where NDVI saturates: 0.1
