Hello, As part of a project requested by the University where I study, I was asked to detect the temporal progression of a cork oak forest (Maamora in Morocco). To do this I turned to the NDVI index but I do not know the values of a pixel of cork oak forest concerning this index. So, I turn to you to give me an interval for the NDVI of the cork oak or why not another indicator that would better detect this kind of forest.
