Normalized Difference Vegetation Index | NDVI in QGIS & ArcMap

About this Video
The Normalized Difference Vegetation Index, commonly known as NDVI, is a crucial remote sensing tool used to assess and monitor the health and vitality of vegetation on Earth's surface. It is a numerical indicator that provides valuable insights into the extent and condition of plant cover in various ecosystems. NDVI is widely employed in fields such as agriculture, forestry, ecology, and climate science to monitor changes in vegetation over time and space.

NDVI is calculated from satellite or aerial imagery and is based on the principle that healthy, green vegetation reflects light differently than nonvegetated surfaces. It measures the difference between the reflectance of nearinfrared (NIR) and red (R) light wavelengths, which are two regions of the electromagnetic spectrum. The formula for NDVI is as follows:

NDVI= (NIRR)/(NIR+R)
​
In this formula, NIR and R represent the reflectance values of the nearinfrared and red bands, respectively, recorded by a remote sensing instrument.
