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.[2]

There are many Vegetation Indices (VIs), with many being functionally equivalent. Many of the indices make use of the inverse relationship between red and near-infrared reflectance associated with healthy green vegetation. Since the 1960s scientists have used satellite remote sensing to monitor fluctuation in vegetation at the Earth's surface. Measurements of vegetation attributes include leaf area index (LAI), percent green cover, chlorophyll content, green biomass and absorbed photosynthetically active radiation (APAR).

Vegetation Indices (VIs) have been historically classified based on a range of attributes, including the number of spectral bands (2 or greater than 2); the method of calculations (ratio or orthogonal), depending on the required objective; or by their historical development (classified as first generation VIs or second generation VIs).[3] For the sake of comparison of the effectiveness of different VIs, Lyon, Yuan et al. (1998)[4] classified 7 VIs based on their computation methods (Subtraction, Division or Rational Transform). Due to advances in hyperspectral remote sensing technology, high-resolution reflectance spectrums are now available, which can be used with traditional multispectral VIs. In addition, VIs have been developed to be used specifically with hyperspectral data, such as the use of Narrow Band Vegetation Indices.

Vegetation indices have been used to:

List of Vegetation Indices

Multispectral Vegetation Indices

NDVI through Landsat 8 applied to the urban area of Ponta Grossa, southern Brazil
  • Ratio Vegetation Index (RVI): Defined as the ratio between the Red and Near Infrared lights of multispectral images [16]
  • Normalised Difference Vegetation Index (NDVI): The most commonly used remote sensing index [17] that calculates the ratio of the difference and sum between the Near Infrared and Red bands of multispectral images. It normally takes values between -1 and +1. It is mostly used in vegetation dynamics monitoring,[18] including biomass quantification.
  • Kauth-Thomas Tasseled Cap Transformation: A spectral enhancement index that transforms the spectral information of a satellite data into spectral features [19][20][21]
  • Infrared Index
  • Perpendicular Vegetation Index
  • Greenness Above Bare Soil
  • Moisture Stress Index: A spectral index that measures the level of moisture stress in leaves [22]
  • Leaf Water Content Index (LWCI) [23]
  • MidIR Index
  • Soil-Adjusted Vegetation Index (SAVI): An adjusted form of NDVI developed to minimize the effects of soil brightness on spectral vegetation indices, particularly in areas of high soil composition [24]
  • Modified SAVI: Mostly applied in to areas with low NDVI measures.
  • Atmospherically Resistant Vegetation Index
  • Soil and Atmospherically Resistant Vegetation Index
  • Enhanced Vegetation Index (EVI): Very similar to NDVI. The only difference is that it corrects atmospheric and canopy background noise, particularly in regions with high biomass
  • New Vegetation Index
  • Aerosol Free Vegetation Index
  • Triangular Vegetation Index
  • Reduced Simple Ratio
  • Visible Atmospherically Resistant Index
  • Normalised Difference Built-Up Index
  • Weighted Difference Vegetation Index (WDVI)
  • Fraction of absorbed photosynthetically active radiation (FAPAR)
  • Normalised Difference Greenness index (NDGI)[25]

Hyperspectral Vegetation Indices

With the advent of hyperspectral data, vegetation indices have been developed specifically for hyperspectral data.

  • Discrete-Band Normalised Difference Vegetation Index
  • Yellowness Index
  • Photochemical Reflectance Index
  • Descrete-Band Normalised Difference Water Index
  • Red Edge Position Determination
  • Crop Chlorophyll Content Prediction
  • Moment distance index (MDI)
