AVI (Advanced Vegetation Index) Calculator

To compute the Advanced Vegetation Index (AVI), multiply the near-infrared reflectance ($NIR$) by $(1 – RED)$ and the difference $(NIR – RED)$, then take the cube root of the result. This formula is a robust indicator of vegetation density and health.

The AVI Calculator is a powerful tool used in remote sensing and environmental monitoring to assess vegetation health and density. By leveraging near-infrared ($NIR$) and red ($RED$) spectral bands, AVI provides a more nuanced analysis than basic vegetation indices. .

Formula

AVI = $[ NIR \times (1 – RED) \times (NIR – RED) ]^{1/3}$

Variable	Description
$NIR$	Near-infrared reflectance
$RED$	Red spectral reflectance
AVI	Advanced Vegetation Index

Solved Calculations

Example 1: Vegetation area with high reflectance

Parameter	Value
$NIR$	0.8
$RED$	0.2
AVI	$[ 0.8 \times (1 – 0.2) \times (0.8 – 0.2) ]^{1/3} = **0.657**$

 

Example 2: Vegetation area with moderate reflectance

Parameter	Value
$NIR$	0.6
$RED$	0.3
AVI	$[ 0.6 \times (1 – 0.3) \times (0.6 – 0.3) ]^{1/3} = **0.491**$
