AVI (Advanced Vegetation Index) Calculator

ByDanielle Danny

To compute the Advanced Vegetation Index (AVI), multiply the near-infrared reflectance (NIRNIR) by (1−RED)(1 – RED) and the difference (NIR−RED)(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 (NIRNIR) and red (REDRED) spectral bands, AVI provides a more nuanced analysis than basic vegetation indices. .

Formula

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

Variable Description
NIRNIR Near-infrared reflectance
REDRED Red spectral reflectance
AVI Advanced Vegetation Index

Solved Calculations

Example 1: Vegetation area with high reflectance

Parameter Value
NIRNIR 0.8
REDRED 0.2
AVI [0.8×(1−0.2)×(0.8−0.2)]1/3=∗∗0.657∗∗[ 0.8 \times (1 – 0.2) \times (0.8 – 0.2) ]^{1/3} = **0.657**

 

Example 2: Vegetation area with moderate reflectance

Parameter Value
NIRNIR 0.6
REDRED 0.3
AVI [0.6×(1−0.3)×(0.6−0.3)]1/3=∗∗0.491∗∗[ 0.6 \times (1 – 0.3) \times (0.6 – 0.3) ]^{1/3} = **0.491**
