Normalized Difference Vegetation Index (NDVI) is used to quantify vegetation greenness and assessing changes in plant health. NDVI is calculated as a ratio between the red (R) and near infrared (NIR) values in traditional fashion, and the value ranges from -1 to +1. This video explains and shows you how to calculate NDVI using QGIS and Landsat 8 Images. Enjoy your watching and subscribe.
In Landsat 4-7, NDVI = (Band 4 - Band 3)/(Band 4 + Band 3)
In Landsat 8-9, NDVI = (Band 5 - Band 4)/(Band 5 + Band 4)
