In this Tutorial we will learn, • How to calculate NDVI in QGIS • NDVI (Normalized Difference Vegetation Index) NDVI is a dimensionless index to measure the state of plant health based on how the plant reflects light. • NDVI formula, NDVI = (NIR - Red) / (NIR + Red) • In Landsat 8-9, NDVI = (Band 5 – Band 4) / (Band 5 + Band 4). • In Landsat 4-7, NDVI = (Band 4 – Band 3) / (Band 4 + Band 3). • Thank you for watching. Hope it will help you to calculate ndvi in qgis .
