4.4 Future possibilities and discussion 
GML (Geography Markup Language) will be prescribed for 
the standard language of the GIS world by ISO in the near 
future. Then the distributed web based GIS server, Geo- Web 
can be made as for the disaster mapping system. Office for 
Outer Space Affairs, United Nations Office at Vienna already 
makes some efforts to establish regional partnerships as for 
disaster management and assessment. The rapidly flood extent 
map server system in this paper will contribute to this kind 
efforts. 
5. CONCLUSIONS 
- The computational new method of combining the terrain 
feature and mathematical morphology will provide the flood 
extent mapping procedure in paddy field areas. This kind 
procedure requires small machine power and they can quickly 
obtain the result. Then it can be used for rapidly flood extent 
mapping for the early warning system of regional and 
agricultural flood damages. Recently as web mapping 
standard is preparing, distributed map server design and its 
experiment is planning among JIRCAS, AIT and PDC.
