Quizplus · Accepted Answer

NDVI (Normalized Difference Vegetation Index) utilizes the red and near-infrared (NIR) bands. The red band is absorbed by chlorophyll in healthy vegetation while the NIR band is reflected by the leaves. The ratio of the reflectance values between these two bands is used to calculate NDVI, which provides a measure of vegetation health and vigor.
