Hi ,

I am evaluating the potentials of using S2 imagery with spectral unmixing techniques to retrieve physical properties of beach sand, such as granulometry, humidity and possibly spectrafacies (intendend as discrete classes of mineral mixtures occurring along the Victorian coastline, Australia).

The endmembers I will use are processed based on my VNIR (350-1075 nm) field spectroscopy campaign (ongoing) and planned Vis-SWIR (350-2500 nm) lab-based spectroscopy of sand samples from cross-shore profiles.

I think I will use Linear Spectral Unmixing, depending of the level of intimate mix I will discover in my sand samples.

However, I find it hard to find good literature.

Any idea??
