Abstract

In recent years, the rapid development of earth observation system and intelligent computing technology provides a rare opportunity for the progress and even change of remote sensing technology. Remote sensing information technology is gradually entering a big earth data era characterized by data model driven and big data analysis. However, in the construction of earth observation system, the “island phenomenon” is ubiquitous. Thus, to develop the data distribution and sharing system for big earth data is among the most advanced international application areas. Firstly, from the view of big earth data, this paper discusses the construction of improved data distribution and sharing system and corresponding system workflow. Then the system key technologies are introduced. Consequently, the application system is shown and discussed.
