Calculating NDVI using Landsat 8 images in QGIS | NDVI Map in QGIS

In this video, we learn how to calculate NDVI in QGIS using Landsat satellite data step by step. First, we understand the complete concept of NDVI (Normalized Difference Vegetation Index), then we explain Landsat bands (NIR and Red), perform practical NDVI calculation in QGIS using Raster Calculator, and finally interpret NDVI values with proper classification ranges. Keyword: NDVI in QGIS, NDVI calculation in QGIS, how to calculate NDVI, NDVI interpretation explained, landsat 8 NDVI tutorial, remote sensing NDVI, NDVI formula explained, vegetation index in GIS, QGIS raster calculator NDVI, NDVI classes low moderate high We also explain standard NDVI value ranges (-1 to +1), low, moderate, and high vegetation categories, and interpret the generated NDVI map with real value ranges. This tutorial is useful for GIS students, remote sensing learners, geography researchers, and anyone working on vegetation analysis, agriculture monitoring, forest mapping, drought assessment, or environmental studies. 👉Topics Covered: NDVI Concept NDVI Formula Landsat 8 Band Explanation NDVI in QGIS NDVI Interpretation NDVI Applications NDVI vs EVI (Advanced Discussion) For more GIS and Remote Sensing tutorials, subscribe to Geo-RemoteSensing. 👍 Don’t forget to Like, Share, and Subscribe for more tutorials on GIS, Remote Sensing, and LULC mapping. 👉 Watch my previous tutorial on How to Download Satellite Images Free | Landsat Data for GIS & LULC Mapping here: 🔗    • How to Download Satellite Images Free | La...   📸 Follow me on Instagram 👉   / georemotesensing   ‪@GeoRemoteSensing‬ Hashtags: #youtubevideo #youtubeviral #youtubetrending #youtube #ndvi #qgis #landsat8 #remotesensing #gis #vegetationindex #ndvimap #geospatial #satelliteimage #agriculturemonitoring #forestmapping #georemotesensing
