# Class Summary
|
||||
This algorithm consists in calculating vegetation indices, these
|
||||
indices can be used for precision agriculture for example (or remote
|
||||
sensing). There are functions to define the data and to calculate the
|
||||
implemented indices.

# Vegetation index
|
||||
https://en.wikipedia.org/wiki/Vegetation_Index
|
||||
A Vegetation Index (VI) is a spectral transformation of two or more bands
|
||||
designed to enhance the contribution of vegetation properties and allow
|
||||
reliable spatial and temporal inter-comparisons of terrestrial
|
||||
photosynthetic activity and canopy structural variations
