| Abstract: | Based on multi-temporal ENVISAT ASAR data,rice mapping was carried out by SAR images. Several issues were discussed in this paper,including SAR data acquisition,data preprocessing,image classi- fication and classification accuracy assessment.By analyzing the radar backscatter of rice,has a unique charac- teristic that its hackscatter changes with its different growth stages. A processing chain for image preprocess- ing and classification for rice was proposed.High classification accuracy 86.640% was achieved in Fuzhou area with the proposed method. |
