Preliminary Comparison of MODIS-NDVI and MODIS-EVI in Eastern Asia

    Graphical Abstract
    • Abstract
  • Typical vegetation in eastern Asia and MODIS data were used to characterize newly-developed Enhanced Vegetation Index(EVI) and widely-used NDVI.The study found that both NDVI and EVI were good indicators for vegetation in wide range from arid to semi-humid area,yet they differed in characterizing dense vegetation: NDVI temporal profile had no clear seasonality with a flat-high curve;and EVI has a clear seasonality with a bell-shaped curve,which has closer relationship to temperature than to NDVI.This may suggest a new opportunity for vegetation study in densely vegetated region.
