WebThe simple ratio vegetation index (termed SR or RVI) is calculated using the following formula. SR or RVI = NIR / RED Or, if no red band is available, SR or RVI = NIR / VIS where NIR and RED (or VIS) are the response in the near-infrared and red or visible bands respectively. Ideally, reflectances WebThe Modified NDVI (MNDVI) ( Nemani et al., 1993) and Reduced SR (RSR) ( Brown et al., 2000) are three-band VIs developed to incorporate SWIR reflectance, which decreases … picture of bags with grocery
