| Abstract: | As a kind of crucial data which was able to reflect the continuous coverage of vegetation on the earth surface,the long time-series MODIS NDVI products have already become a reliable data source used in remote sensing for crop measurement.In this paper,a long time-series and high-resolution(250m) MODIS data in 2008 was used to extract the area of the paddy land in Jiangsu Province,China.In the beginning,an annual time-series NDVI dataset of the study area was built up by pre-processing,and a reconstruction ... |
