Vegetation Indices A review of commonly used spectral indices
What is a vegetation index?
In this article we are going to explore a few spectral indices focused on understanding the vegetation.
VI or Vegetation Index is actually a spectral index, i.e. a combination of spectral bands. You can read more details about spectral indices in a few of my previous articles: "Spectral Indices with multispectral satellite data", "Spectral Indices in Remote Sensing and how to interpret them", "SAVI and NDVI spectral index comparison"
So, since VI is a actually a spectral index, why to differentiate it?
As the name suggests, it reveals many properties of the vegetation.
