Normalized difference vegetation index (NDVI) A simple spectral vegetation index. Description NDVI is a vegetation health indicator. It’s the most widely used index in agriculture because it’s straightforward to calculate, and most satellites can obtain the 2 bands needed for it....
As shown below,Normalized Difference Vegetation Index (NDVI)uses the NIR and red channels in its formula. Healthy vegetation (chlorophyll) reflects more near-infrared (NIR) and green light compared to other wavelengths. But it absorbs more red and blue light. ...
29.2.3.1Normalized Difference Vegetation Index The NDVI is a common and widely usedremote sensingindex (Bhandari, Kumar, & Singh, 2012). NDVI is calculated as the ratio between TOA reflectance of a red band(ρred)around 0.66μm and a near-infrared (NIR) band(ρnir)around 0.86μm. The ND...

1)normalized difference vegetation indexNDVI 1.On the basis of Normalized Difference Vegetation Index (NDVI) data with resolution of 1 km of NOAA/AVHRR in 1993 and NDVI data for MODIS in 2000 and 2006,the authors analyzed the NDVI spatial dynamic variations by changing intensive parameters in th...
Normalized Difference Vegetation Index (NDVI) has played an important role in assessing green plant biomass through remote sensing on global scale since the early 1970s. The concept of NDVI is based on the fact that green plants show higher reflection in near-infrared region than in visible regio...
