The Abstract graphical Grid workflow can adapt the dynamic nature of Grid environment. It is more intuitive and convenient for user to apply Grid services solving the remote sensing distributable computing problems than concrete Grid workflows. This paper firstly introduces the feasibilities and advantages of abstract Grid workflow applying for remote sensing quantitative retrieval services. And then it gives the relative research status about science workflow applied to geosciences' domain. In the design of Grid workflow data structure, the authors illustrate the abstract Grid workflow's data structure for remote sensing quantitative retrieval. And then the authors give the key operation algorithms of the abstract Grid workflow data structure. In the implementation part, the authors have completed the abstract graphical Grid workflow composition system for remote sensing quantitative retrieval service. Using it, users can construct a workflow based on remote sensing application just by dragging and clicking the components of interest provided by the system.
