Vegetation phenology tracking
Quick Stats
Category: vegetation
Sensor: TripleSat
Provider: 21AT
Bands Used: 2
Description
A vegetation index designed to improve sensitivity for moderate to high biomass conditions where traditional NDVI saturates. The weighting factor (0.1) enhances the dynamic range of the vegetation signal.
