Vegetation index using the Raster Calculator
- Click the Add raster layer
and select a multiband Sentinel-2 satellite image
- Check the rank and spectral range of bands in the multiband file (e.g. see table Changing Raster Layer Style).
- After clicking Open, the raster layer appears in the QGIS canvas.
- Click Raster --> Raster calculator.
- A powerful normalization is realized by the normalized difference vegetation index that forms the basis of most vegetation indices $NDVI = (NIR-Red) / NIR + RED$
