Estimating Paddy Area in Shanghai Region Using NOAA/AVHRR Data

The data of NOAA/AVHRR, because of their some advantages, have been applied in many fields including estimation of crop area. This research applies fuzzy supervised classification to decomposing the mixed pixels of NOAA/AVHRR data and estimates the paddy area of 10 counties in Shanghai during 1992 and 1993. As compared with the statistic data in the same period the results show that the overall accuracies (ratios of estimated to statistic area) are 92.0% and 95.4%, respectively
