Quick Stats
Category: vegetation
Sensor: Jilin-1 GF03D
Provider: CG Satellite
Bands Used: 3
Description
The Visible Atmospherically Resistant Index (VARI) is designed to emphasize vegetation in the visible portion of the spectrum while mitigating illumination differences and atmospheric effects. It evaluates the 'greenness' in plants using only visible light bands, making it ideal for standard RGB cameras without requiring specialized multispectral sensors.
