Abstract :
The water surfaces detected by a conventional intensity based method from JERS-1 SAR images do not always coincide with the flood-damaged areas especially existing paddy fields. The authors propose morphological methods as spatial information. The result roughly agree with the reported flood-inundated areas. We concluded that this kind of methods has an advantage of the disaster monitoring using SAR satellite.
