Normalized Material Suspended Index (NMSI)

NMSI  is  an  algorithm  that  can  analyzesuspended  material  in  water  by  estimated  and normalized based on the spectral reflectance in the channel in the visible wave range including blue, green and red channels.

The NMSI equation is as follows

NMSI = (red band + green band - blue band) / (red band + green band + blue band)
