A framework for land-surface remote sensing data sharing and collaboration

In order to establish a collaborative decision making environment for scientists, we proposed an original approach to integrate remote sensing data and remote sensing analysis tools based on Web Service and GRID. The proposed framework consists of four tiers and provides three level services. Firstly, the analysis of RS information sharing is made with data resource sharing, computing resource sharing and knowledge resource sharing. Then, the framework of RS data sharing and collaboration is designed with the request of RS information sharing. The proposed framework consists of four tiers and can provide three level services. Finally, the implement of the framework is described. The three key systems, RS data retrieval and publishing system, RS processing service and Workflows system and Geo-collaboration and decision-making system are introduced in detail.
