The Communication Framework Research Of Service GIS Based On Heterogeneous Platform

After years development of geographic information system industry, GIS application is gradually moving towards all aspects of people’s daily life from the field of scientific research, education, government decision-making and so on. In the development process, how to take full advantage of the construction of various types of GIS resources with the new requirements of business, to develop a GIS service application which fully meet the functional requirements and has a good experience of operating. It has been turned into one of the direction of the development of GIS technology. After researching the technical requirements of GIS service platform which require to integrate the GIS resource distributed in different site and developed in different program language, and to keep the system performance is good, paper had studied the current technologies of distributed computing and made an analysis of the technologies to find the fittest one as the basis of the communication framework. The fittest technical is Ice called Internet Communication Engine. Ice’s distributed computing solutions called IceGrid as the basis for the communication framework, with the method a software design idea called software service bus, paper had studied to complete a communication framework technical specification which consists of service bus, registry service, load balancing service and developing service interface model. As the construct of the communication framework technical specification, paper had developed a GIS Service of soil erosion analysis, in order to verify the ability of a communications framework to integrate GIS resources, to show based on the development model of communication framework for the development of GIS services, as well as the performance of the system, and to express the usage of the communication framework in the actual production.
