The formula to calculate the Advanced Vegetation Index (AVI) is:
\[ AVI = \left[ NIR \cdot (1 - RED) \cdot (NIR - RED) \right]^{1/3} \]
Where:
Let's say the near-infrared light value (NIR) is 0.8 and the red light value (RED) is 0.2. The advanced vegetation index (AVI) would be calculated as follows:
\[ AVI = \left[ 0.8 \cdot (1 - 0.2) \cdot (0.8 - 0.2) \right]^{1/3} \approx 0.74 \]
So, the advanced vegetation index (AVI) is approximately 0.74.
The advanced vegetation index (AVI) is a valuable tool used for the assessment and monitoring of vegetation health and productivity. It combines satellite imagery and various mathematical algorithms to provide an accurate representation of the condition and vigor of vegetation cover.
