4. CONCLUSIONS 
The flood possible extents derived from PALSAR data using 
morphological procedure agree with the reported flood areas. 
And the calculation result using this method can be obtained 
very swiftly. Therefore this method is well matched with “the 
platform system for disaster-related information sharing”. The 
technology of Geo-Web or Geospatial Semantic Web will be 
the foundation of such kind system in the next generation.
