Client-Server Interaction in GIS Applications Through Web Services
نویسنده
چکیده
Web services have been developed and deployed for GIS applications. Client-server interaction in such applications is limited by the service provider, such as ArcWeb Service. This paper will discuss the needs from service requester which lead to the exploration on the design and manipulation of Web Service interface. It is likely that GIS Web Service promotes the separation of spatial feature and non-spatial feature as well as the data processing modules, considering that Web Service is developer oriented rather than end-user oriented. It will demonstrate that through spatial feature interface development, user-specified real-time dataset can be transferred and integrated in GIS applications through Web Service deployment. Scalable Vector Graphic (SVG) can be an alternative choice in GIS Web Service development and deployment while ArcGIS Server 9.x can offer strong server functions for Web Service development in the near future. Both advantages and disadvantages of these two technologies will be investigated and demonstrated.
