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. Render type: multiband file).
- After clicking Open, the raster layer appears on the QGIS canvas.
- Click Processing --> Options. Unfold the General folder. Switch the checkbox on: Keep dialog open after running an algorithm.
