Normalized Difference Vegetation Index (NDVI) is a widely used remote sensing metric for vegetation monitoring and land cover classification. This study demonstrates the use of QGIS, an open-source Geographic Information System, to calculate NDVI using Landsat 8 imagery for a selected area of interest. The approach involves loading satellite bands, performing raster calculations, and visualizing NDVI values to assess vegetation health. The method provides a cost-effective solution for environmental monitoring, agricultural planning, and urban green space analysis.
