  "name": "Color-infrared (CIR)",
  "description": "CIR, is short for Color Infrared. Here it refers to rendering a multi-spectral imagery (generally at least 4 or more bands) with NIR (Near Infrared) band, Red band and Green band for the three color guns of Red, Green and Blue, respectively. The resulting image is good for delineating plants, such as its species and biomass. It can also be used in estimating soil moisture and water clarity, and among other uses.",

  "name": "Normalized Difference Vegetation Index (NDVI)",
  "description": "NDVI, is short for Normalized Difference Vegetation Index. It basically is the spectral ratio of NIR minus Red to NIR plus Red for a multi-spectral imagery. The ratio itself ranges from -1 to +1. As the name implies, it is highly correlated to the amount of vegetation on the ground, e.g. the higher or more positive the value is, the more vegetation for a given pixel. It has also been used to estimate other plant properties, such as leaf area index, biomass, and chlorophyll content.",
