%
{ %%%%%% Algorithm summary %%%%%%
Calculation of Disease Water Stress Index (DWSI-5)
}
%
{ %%%%%% Category %%%%%%
Biophysics - water (stress) indices
}
%
{ %%%%%% Inputs %%%%%%
Narrow band multi- or hyperspectral imagery (ENVI standard image data) including channels close to the wavelengths of 549nm, 680nm, 803nm and 1659nm.\bigskip
}
%
{ %%%%%% Outputs %%%%%%
Single band with DWSI5 values
