Abstract

Abstract: By applying the FLAASH,ETM+ image of landscape district of Sun Yat-sen mausoleum was corrected for atmospheric effects to generate the apparent reflectance and the surface reflectance products.After applying the DN image,apparent reflectance image and surface reflectance image to calculate the NDVIs,the functional correlations were built between those NDVIs and forest volume with different functions.It was found that NDVI calculated from surface reflectance had the best correlation with forest volume and could truly show vegetation cover of surface.

Key words: NDVI, atmosphere correction, forest volume, correlation
