Building Grid GIS Service with WSRF

With the rapid development of grid technology, studies on building web spatial analysis functions under grid environment have become the research hotspot of GIS. To implement complex geo-processing functions, it may need to integrate several different GIS service, which is usually distributed in different computer. Grid GIS provides a highly interactive and cooperative mechanism in implementing and integrating the geospatial service. This paper first briefly introduces the most important part in building Grid service-WSRF, then give an example to illustrate how Grid enabled GIS service can bring higher efficiency and make GIS service more cooperative than traditional GIS service.
