Abstract:

The difference of vegetation index of EOS/MODIS and FY3/MERSI were reported in this paper. EOS/MODIS and FY3/MERSI data of august 16,2008 and august 30,2009 were acquired respectively and the vegetation index of EOS/MODIS and FY3/MERSI were calculated in different land, such as forest, bosk, corn, paddy, city, sandlot and so on. This paper analyzes the relationship between MODIS/NDVI and MERSI/NDVI of the same region at different time, based on histogram and Feather Space methods. The results show that their shapes are the same in the histogram, and the range of their values has consistent region. Each inversion result of various kinds of ground objects shows a better linear consistency, the maximum R2 is forest land, which reaches to 0.8624.
