    This is my location : Near Montpellier In South of France. The red field in your NDVI are salt marshes or swamp area with some fields. But anyway, thanks for the probative demo.

    Can you use this method to know soil composition under the top soil such as clay or iron rust.

      Short answer, no. You need sensors that "see" the things you want to analyse. However, it might be possible to "infer" properties under ground based on what is found on top.

    Thanks for a great tutorial. Just a question for your Symbology tab, where you discussed the importance of having the range going from -1 to +1. This makes sense according to the NDVI value range, but I have tried changin this to extreme off-set levels (-8 to +8). Running af raster statistics analysis shows exactly the same values (mean, range etc). Am I doing something wrong or why is this?

      It only influence the visual style. Not analysis values.

      The source described in the video does have world coverage.
      If you want higher resolution, there's a lot of commercial companies that sell imagery. Try "Planet" for really up to date imagery.
