| Abstract: | The basic principle and method for extracting the flood-inundated area from remote sensing data obtained by JERS-1 SAR are investigated in this paper. The method includes geometric correction, enhanced frost filter processing and threshold processing. The JERS-1 SAR data of Dongting Lake region during flood in May 1995 are used for research and analysis with the method. The result shows that the flood-inundated area can be obtained effectively, accurately and rapidly in the presented way. |
