Sentinel-2 TVI
Triangular Vegetation Index for Sentinel-2
Vegetation Satellite Provider: ESA
Applications
Chlorophyll content estimation
Green LAI prediction
Crop canopy analysis
Vegetation health monitoring
Precision agriculture
Quick Stats
Category: vegetation
Sensor: Sentinel-2
Provider: ESA
Bands Used: 3
Description
A vegetation index that uses the triangular area formed by green, red, and red-edge reflectance values. It is sensitive to leaf chlorophyll content and is particularly useful for estimating green LAI.
