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?

  1. First, determine the reflection in the near-infrared spectrum.

    Measure the total reflection in the near-infrared spectrum.

  2. Next, determine the reflection in the red range.

    Measure the total reflection in the red spectrum.

  3. Finally, calculate the NDVI.

    Calculate the NDVI using the formula above.
