5.CONCLUSION 
In order to use present and future Japanese earth 
observation system to earth environmental 
monitoring system, it was stressed that global 
datasets and global data network should be 
constructed to monitor environment in the world. 
In addition to development of space segment, 
NASDA will contribute to construction of global 
environmental data sets and network with other 
domestic and foreign organizations.
