Research on resources environment data grid

Because of the significance of resources environment research and the urgency of data share, there needs a new research platform. This platform can share resources environment data, computation resources, model arithmetic, and software tool. According to the application need mentioned above, we put forward the resources environment data grid which contains three layers. Furthermore, three key technologies are analyzed in this paper: resources environment data grid middleware, data resources gridding and grid services chain model. Under the environment of J2EE, following the specification of OGSI and the OWS spatial information, using Web Services technology, resources environment data grid can be realized.
