NDVI is used to quantify vegetation greenness and is useful in understanding vegetation density and assessing changes in plant health. NDVI is calculated as a ratio between the red (R) and near infrared (NIR) values in traditional fashion: (NIR - R) / (NIR + R) In Landsat 4-7, NDVI = (Band 4 – Band 3) / (Band 4 + Band 3).

NDVI is a pixel-by-pixel mathematical computation performed on an image with GIS tools. It is a plant health indicator determined by measuring the absorption and reflection of red and near-infrared light. NDVI may be used to study land all over the world, making it suitable for both focused field studies and continental or global-scale ...
