is it mandatory to rescale the satilite image before starting the classification and calculating the spectrales indexes?
thanks for your comment, not at all its optional
hello. can you please explain where did you get (0.2 to 5)as the coverage area of vegetation ? is it the spectral range??thanks alot for your time
thanks for your video. why did you use 6000 value in formula.
you're welcome because based on our greatest value available on this image, and we did to rescale (change the values between 0 and 1)
@@abdulbaserqasimi6530 ok. But ı am using always "float((b1 le 0)*0 + (b1 ge 10000)*1 + (b1 gt 0 and b1 lt 10000)*float(b1/10000.0))" this formula for changing the values between 0 and 1.
