NDVI Formula
The following formula is used to calculate the NDVI.
NDVI = (NIR -RED) / (NIR + RED)
- Where NDVI is the normalized difference vegetation index
- NIR is the reflection in the near-infrared spectrum
- RED is the reflection in the red range of the spectrum
NDVI Definition
NDVI is short for normalized difference vegetation index, and it is a metric that described the density of vegetation of an area based on satellite imagery.
NDVI Example
How to calculate NDVI?
- First, determine the reflection in the near-infrared spectrum.
Measure the total reflection in the near-infrared spectrum.
- Next, determine the reflection in the red range.
Measure the total reflection in the red spectrum.
- Finally, calculate the NDVI.
Calculate the NDVI using the formula above.
FAQ
NDVI stands for normalized difference vegetation index. It’s a measure of the density of vegetation of an area based on an image.
