Calculating Normalized Difference Vegetation Index NDVI Using ENVI Classic

The normalized difference vegetation index is a simple graphical indicator that can be used to analyze remote sensing measurements, often from a space platform, assessing whether or not the target being observed contains live green vegetation.
Range: -1 to +1
Vegetated areas will generally yield high values for NDVI because of their relatively high NIR reflectance (0.7 - 1.1 μm) and low visible reflectance (0.58 - 0.68 μm)
NDVI shows as a high value for denser vegetation, while the NDVI is very low in desert, or non-vegetation regions
