Hi, thanks for this tutorial! I am working to derive fractional cover of prosopis in Baringo using landsat imagery. My output returns includes also negative values and range values beyond 0 and 1 even after summing the constrain to one. I used five(5) endmembers. Kindly could you help on how to interpret these results? what does Binsize value on th ROI statistic represent? What is the range of values for fractional cover?
