Research of the application of Grid computing on geographical information system

摘要

Data Distribution of GIS has been made realization through WebGIS. With the increasing need of data sharing and GIS, WebGIS can no longer meet this need. Grid computing is a sharing model presented by computer experts to solve current network resources imbalance problem. This paper analyzes the weakness and problems of traditional GIS, and then gives the method of solving these problems with the technology provided by grid computing and web services. With the technology of middleware, this paper presents the architecture of Grid GIS and lists the techniques it needs. At last the paper discusses its implementation process of Digital Coal Mine Safety Grid GIS.
