Research of Spatial Decision Support System Construction Based on Cloud Model

This paper analyzes the characteristics of spatial decision support system, status quo and development trends, then proposes the thoughts of constructing spatial decision support system services by the help of cloud computing and based on the Space geography knowledge. The construction of Spatial Decision Support System which is based on Cloud model mainly includes a multi-source services publishing tool, combined with the basic functions of web site management to achieve integration of spatial decision-making information systems to build and publish. This paper focuses on information organization and design, and publishes a variety of services to a unified source of the entrance to form a standard service cloud, user-friendly and made the service access control strategy for cloud classification, through the hierarchical control structure of the services of varying competence cloud, to build the secure cloud environment.
