Research and Realization of the Web-based Integration System of Gis and Oa

This paper presents a study on the feasibility, mechanisms and key technology for integrating GIS and OA in the Browser/Server (B/S) architecture, on the basis of a comparative analysis of the independent development model and the integrated development model of GIS and OA. Presently, the development of GIS and OA is mainly based on the two models: Mainframe-Terminal (M -T) model upon stand-alone computer and Client/Server (C/S) model upon Intranet; and the integration of them is only on the functional level. The paper discusses various possibilities of using advanced technologies, such as ASP (Active Server Pages), ActiveX/OLE, etc. for the Web-based integration of GIS and OA in the B/S architecture. The integration system realizes the close connection and communication between spatial data (GIS) and non-spatial data (OA), and realizes both GIS and OA functions, such as query, statistics and analysis. It realizes the function integration completely and the information integration in some degree. A case study is also presented, which shows an approach for realizing the Web-based GIS and OA integration system. With this integration system, not only the working efficiency and quality are improved, but also the traditional office management model and concepts are transformed completely.
