Distributed decision-support GIS application based on web-service

摘要

As web-GIS is more and more widely used in DSS system, more emphases are put on the information sharing and interaction between distributed applications. This paper suggests a CSCW structure based on SOA to provide decision support in distributed environment. This technique focuses on data sharing, knowledge sharing, knowledge storing, and knowledge based decision support service. As illustrated in the last chapter, it works effectively and stably, forming a cooperative model for DSS in distributed environment.
