AbstractImage simulation of EOS MODIS data has been carried out spectrally and spatially using an AVIRIS data set acquired over mountainous terrain in British Columbia. The influence of atmospheric variations due to terrain elevation on vegetation indices derived from NOAA AVHRR and simulated EOS MODIS data types has been investigated. The results indicate that the terrain elevation dependence of the Normalized Difference Vegetation Index (NDVI) is significant and increases with decreasing vegetation density.
