摘要：With the increasing application requirements of spatial information, traditional spatial information techniques can not solve current application problems. As novel technologies that can implement sharing of enormous distributed resource, Grid and Web services provide an effective and efficient way to share and integrate spatial information on the web. Hence, an innovate framework, i.e. Spatial information Grid (SIG), is proposed. We put research emphasis here on system architecture of SIG in order to provide technical foundation for succeeding research of SIG. Furthermore, we discuss service composition technology and introduce a workflow model which called SRN. Finally, we illustrate application patterns of SIG and present an application example in geological survey based on SIG framework to validate the practicability of SIG
