| Abstract: | Space-Air-Ground integrated earth observation network（SAGIEON） is not only the most promising high-tech area,but also a fundamental infrastructure closely related to national security and economic/social development.Firstly,the scientific concept,key technologies,current situation and tendency of SAGIEON are comprehensively represented.Secondly,an integrated data processing system for native remote sensing satellites is introduced,including its objectives and key technologies.Thirdly,the connotation of generalized spatial information grid are proposed on the basis of the above mentioned discussions.Finally,some conclusions are drawn.For the propose of providing fast,precise and real-time spatial information service to everyone,it is very important to carry out research on the theories and technologies of SAGIEON. |
