Abstract
Future direction of the development on satellite data utilization system from user-oriented point of view is figured out, considering the foreseeing trend on space and ground segments which are rapidly growing up year by year. New generation of Internet and World Wide Web will extremely affect a interactive function between users and the future system. The generation of value-added and higher-level satellite data products, which will be required by wide variety of science communities, will be a most complicated function in the development of the future system. The next-generation satellite data system, integrating satellite data products with geo-spatial scientific and socio-economic data and providing new information to the public, will be a core system in the digital society.
