Research And Realization Of Commercial Real Estate WebGIS Based On Services

With the rapid development of economy and society in China, the development and construction of commercial real estate also grow rapidly. The development of real estate is long-lasting and high-risk, involving planning design, construction, investment leasing, property management and many other business sectors. How to publish, manage, integrate and share the data produced during the projects'operation process effectively, and provide comprehensive information service for every stage in a fast, accurate and completely way are the problems faced by each commercial real estate project.In this paper, we conduct the research based on the development of Lujiazui financial center (2nd phase) WebGIS system. The paper summarizes current problems and GIS using status in the development of commercial real estate and studies the related theory of WebGIS and implementation technology. Also, the paper analyzes the new generation WebGIS, which is spatial information services-oriented and based on AJAX, and design the system architecture, function modules and database by combining the WebGIS and commercial real estate business logics. Finally, the paper develops a commercial real estate information system based on WebGIS, which has been applied into the Lujiazui financial center (2nd phase) WebGIS platform project.In the theory section, the paper firstly studies the principle of WebGIS and implementation technology. Then it discusses the WebGIS based on spatial information services-oriented architecture, and moreover, it takes the ArcGIS Server as the research object, specifically discussing the type of spatial information service, service management, pooling and non-pooling service, the map service cache etc. Finally this paper discusses the realization principle of AJAX and practical significance of combining AJAX with WebGIS; analyze the realization of AJAX in ASP.NET framework and.NET Web ADF framework. This paper brings the WebGIS into the field of commercial real estate information management, exploring how to integrate the graphical information, text information and spatial information, which are relevant with project, in each department based on WebGIS, realizing the release, management, integration and sharing of information during the planning, construction, investment and operation phases. The research achievements and innovations in this dissertation are as follows:1. Closely combine B/S structure, GIS functionality and business logic, integrate the existing data of office automation systems and project management systems and realize the network share of spatial geography information and real estate data as a result.2. On the basis of studying spatial information services-oriented architecture and ArcGIS Server, the author developed a system that is not only achieved traditional functions, such as map view, map measurement, information query and map output etc. but also brought the geo-spatial analysis and exchanged map service data source dynamically into WebGIS.3. Develop the system based on AJAX, improve the user's experience and reduce network traffic.
