STUDY OF ARCHITECTURE TECHNOLOGIES IN SPATIAL INFORMATION RESOURCE APPLICATION SYSTEM

摘要

To coordinate distributed spatial information resources and play their important roles effectively, we have studied promising paradigms of distributed system and application as well as key technologies, which has showed definite results. Using web services, grid computing and p2p technologies, we build a four-layered spatial information resource application system architecture which is distributed, loose coupled, self-organized, robust and scalable. Apart from these characters, ontology technology is also used to get resources more effectively.
