# 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
