Different Interface, Policy, Owner, Model
Different Interface, Policy, Owner, Model
High Level UserCannot directly get the detail information (in-situ
data etc.) storied in low level data centerCannot get thematic statistic information on-line
Low Level UserCannot get powerful process supportCannot get real-time satellite data
The attempt to uniform the archived data format and interface is impossible
