Normalized Difference Vegeta4on Index: an <br />
index of greenness <br />
NDVI = (NIR-‐R)/(NIR+R) <br />
NIR = spectral reflectance in the near-‐infrared band <br />
(0.725 -‐ 1.1µm), where light scaXering from the canopy <br />
dominates, <br />
R = reflectance in the red, chlorophyll-‐absorbing por@on <br />
of the spectrum (0.58 to 0.68µm).
