Abstract :
In this study, we comparison of NDVI of ground measurement, atmospheric corrected ASTER LIB data and ASTER surface reflectance product (AST07) data to evaluate the accuracy of the ATCOR software atmospheric correction of Terra/ASTER data (Jun 30, 2002), using ground radiometric measurement data (ASD´s FieldSpecreg Pro). Our research selected the study area Sarobetsu Marsh located in coastal area of Hokkaido, Japan. We found that 5% of scattering radiation is contained with the ASTER Green band and 47% of radiation was absorbed in the ASTER NIR band and 17% of radiation was absorbed in the ASTER SWIR6 band. And that the ASD´s measurement values and the ATCOR software output values are no big difference in the ASTER reflection band and absorption bands of chlorophyll (i.e. NIR-band and Red-band); However, the difference was see in the ASTER scattering bands (i.e. visible Green band) and soil reflection bands (i.e. ASTER SWIR bands). Compared with the data of ASD´s measurement, the AST07 (copyNASA/EOSDIS ASTER surface reflectance product data (L2B)) values are too low in a NIR band.
