normalized difference vegetation index
The measure and monitoring of plant growth (vigor), vegetation cover, and biomass production from multispectral satellite data (Red and Green: see Red, Green, Blue). The NDVI image maps shown here are prepared from 1-km AVHRR spectral data in the visible (Channel 1; 0.58-0.68 micrometers) and near infrared (Channel 2; 0.725-1.10 micrometers) regions of the electromagnetic spectrum.
