Vegetation Indices

Contributors: Michele Croci

Dinh Ho Tong Minh added in radar indicators

This repository is inspired by "davemlz/awesome-ee-spectral-indices", but with the aim of collecting specific vegetation indices for crop monitoring 🌱🌾 and precision agriculture 🚜.

The ready-to-use curated list of spectral indices (check the list here) for remote sensing applications is presented here. The list is available in the csv formats (CSV).

Attributes

Each item of the list has the following attributes:

• short_name: Short name of the index (e.g. "NDVI").
• long_name: Long name of the index (e.g. "Normalized Difference Vegetation Index").
• formula: Expression/formula of the index (e.g. "(N - R)/(N + R)").
• bands: List of required bands/parameters for the index computation (e.g. ["N","R"]).
• reference: Link to the index reference/paper/doi (e.g. "https://doi.org/10.1080/01431169608948714").
• type: Type/application of the index (e.g. "Biomass").
• date_of_addition: Date of addition to the list (e.g. "2022-01-01").

Expressions

The formula of the index is presented as a string/expression (e.g. "(N - R)/(N + R)") that can be easily evaluated. The parameters used in the expression for each index follow this standard:

Description	Standard	Sentinel-1	Sentinel-2	Landsat-8	Landsat-457	MODIS
Aerosols	A		B1	B1
Blue	B		B2	B2	B1	B3
Green	G		B3	B3	B2	B4
Red	R		B4	B4	B3	B1
Red Edge 1	RE1		B5
Red Edge 2	RE2		B6
Red Edge 3	RE3		B7
Red Edge 4	RE4		B8A
NIR	N		B8	B5	B4	B2

SWIR 2	S2		B12	B7	B7	B7
