Abstract: This paper proposes a high-level structure of the sharing platform which has five-layer architecture with the ideas of grid and Service-Oriented Architecture(SOA) design. It analyzes the composition and functionality of each layer, and researches the key technologies of constructing the sharing platform, including remote-sensing metadata standards, design of system framework and Web services and workflow technologies. The sharing platform provides a feasible solution to implement the sharing of remote-sensing information resources.

Key words: Web service, sharing of remote-sensing data, workflow
