The Quantum Geographic Information System (QGIS) Sentinel Vegetation Indices (QSVI) plugin is an efficient, user-friendly tool designed to calculate key environmental remote sensing indices. Developed using a Python library within the QGIS software, QSVI significantly reduces computation time, exceeding other popular GIS applications. This study demonstrates its effectiveness in processing large datasets, offering a cost-effective solution for environmental monitoring and analysis, which is particularly valuable in educational settings.
