{ %%%%%% Algorithm name %%%%%%
biophys\_indices (NDVI is one index calculated within the overall program)
}
%
{ %%%%%% Algorithm summary %%%%%%
Calculation of Normalised Difference Vegetation index (NDVI)
}
%
{ %%%%%% Category %%%%%%

%
{ %%%%%% Inputs %%%%%%
Multi- or hyperspectral imagery (ENVI standard image data) including channels close to the wavelengths of 671nm and 864nm.\bigskip
}
%
{ %%%%%% Outputs %%%%%%
Single band with NDVI values
}
%
{ %%%%%% Formula %%%%%%
\begin{displaymath}
NDVI = \frac{R_{864}-R_{671}}{R_{864}+R_{671}}
\end{displaymath}
