【摘要】 在我国,房地产业已经成为国民经济的支柱产业,对经济的发展和经济结构的调整都发挥着越来越重要的作用。而房地产管理中一项重要的基础性、服务性工作——房地产测绘,为房地产开发、经营以及交易提供基本的信息服务。因此,在信息化的背景下,依托新的信息技术发展和完善房地产测绘信息管理系统,是房地产测绘信息化建设的重要内容,也是房地产测绘信息管理的现实需要。本论文首先论述当前房地产测绘信息管理的现状,分析其存在的问题,阐述以新的信息技术建立房地产测绘信息管理系统的重要性。其次,从房地产测绘信息管理系统的功能出发,着重分析该系统的三大功能模块——用户管理模块、WebGIS模块以及业务管理模块,并详细探讨各个功能模块的实现技术及各自的结构模型设计。在用户管理模块,采用Web Services技术构建基于分布式的结构模型;在WebGIS模块,通过对ArcIMS的二次开发设计基于服务器的WebGIS;在业务管理模块,利用Struts技术创建基于MVC设计模式的结构模型。在此基础上,设计了基于WebGIS和Web Services技术的城市房地产测绘信息管理系统。此外,本文还详细介绍系统开发过程中所用到的各种关键技术及其解决方案。在数据组织上,采用数据库管理软件Microsoft SQL Server,对于不同的功能数据存储在不同的数据库表中,不同的数据库表之间利用关键字段进行关联;在数据库连接上,为提高数据的读取效率,采用数据库连接池技术;在图形数据处理方面,利用数据转换软件,将数据转换成ArcIMS能够发布的数据格式;在业务流程设计与实现上,通过实地调查,设计了清晰简洁的业务操作流程。在上述研究的基础上,从用户的需求出发,开发了基于WebGIS和WebServices的房地产测绘信息管理系统,并应用于上海市嘉定区房地产测绘信息管理,从而验证了本文提出的技术和方法的可行性,取得了较好的应用效果。最后,对全文进行总结,并对进一步的工作进行了展望。本文得到国家自然科学基金项目(40771174)等资助。更多还原

【Abstract】 In our country, real estate has become a pillar industry of the national economy and has played an increasingly important role in economic development and the adjustment of economic structure. As an important basic and service activity in this industry, the real estate mapping provides fundamental information to development, management, and transaction of real estate. Therefore, in the context of the information-based, it is urgent affairs and important matters for real estate mapping informationization and management to develop and improve real estate mapping information management systems.In this paper, the current situation of real estate mapping information management was discussed. Existent problems were analyzed. And importance of establishing management system for real estate mapping was illustrated. Then, according to functions of management system, three main modules - User management module, Business management module and WebGIS module were typically analyzed. In detail, the technologies used to realize these modules, structure design for each module and design of the whole system were presented. In user management module, Web Services technology was used to construct a component-based model; in the WebGIS module, a server-based WebGIS was designed through secondary development of ArcIMS; in business management module, a MVC based structural model was created through Struts technology. On the above basis, a WebGIS and Web Services technology based urban real estate information management system was designed.In addition, various key technologies and solutions used in developing the system were detailed explained. Microsoft SQL Server was applied to organize the data which were stored in different data tables by different functions, and these data tables connected with each other by keywords; with respect to database connectivity, database connection pool technology was used in order to improve the efficiency of data access; during graphical data processing, data conversion software was used to transform the data into the format which is suitable for ArcIMS distribution; in the business process design and realization, clear and concise business operation process was designed by field investigation.With the research work mentioned above, real estate mapping information management system based on WebGIS and Web Services was developed to meet users’ needs and demands. This system was also applied to JiaDing district in Shanghai to demonstrate the feasibility of the technologies and methodologies presented in this paper, which obtained satisfying achievement.Finally, summary of this paper and prospect for further work were presented.This paper is supported by the National Natural Science Foundation of China (Grant No. 40771174).更多还原
