The Design and Implementation of GIS Grid Services

摘要

This paper illustrates a GIS (Geographic Information Systems) application integration framework, which utilizes GIS Grid services (GGS) to enable large-scale resource sharing and better reusing of legacy systems. Considering the fundamental requirements of GGS, a design with sophisticated interfaces which enables explicit state semantics is proposed as a major contribution of this study. In addition, a prototype system of GGS based on legacy systems and web services is developed. Furthermore, the implementations are evaluated in a grid service selector environment proposed in another paper of this project.
