摘要：
Spatial Data Grid allows for solving larger problems and executing applications that traditional Web GIS (Geographic Information System) can not handle efficiently. In Spatial Data Grid, all functions of GIS are encapsulated as stateful Web Services. The purpose of this paper is to design and implement a new mechanism to organize miscellaneous Vector Map Services, built on GT4 (Globus Toolkit 4), and based on WSRF (Web Services Resource Framework). In this paper, we demonstrate the general procedure to build a Grid Vector Map Service (spatial query, buffer analysis, overlay analysis, etc) based on GT4. We design and implement two kinds of Vector Map Services: Domain Service and Node Service, which can be chosen by users after they log in the Grid Portal correctly. Finally, we present some experimental results and draw some conclusions. The new mechanism allows more flexible usage of available resources in the Grid and is expected to decrease the efforts needed to configure and maintain nodes in the Grid, and it buffers some frequently accessed information in resources, in this way, access times of GIS Server will be sharply decreased and query time will be reduced.
