In this tutorial, we learn how to automatically extract NDVI zones above a specific threshold from a high-resolution raster image using Python in QGIS.

The study focuses on the Montagne de Reims region in France, demonstrating step-by-step how to filter NDVI values, convert raster data to vector shapefiles, and visualize the results for vegetation monitoring.

Datasets used:
High-resolution satellite NDVI raster image of Montagne de Reims, France (Source: European Space Agency - Copernicus Program),

Software:
QGIS (Open Source Geographic Information System)
PyGIS
