Enter the reflection in the near-infrared spectrum and the reflection in the red rand of the spectrum to determine the normalized difference vegetation index.

## 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.
