【摘要】：人类对地理信息的使用由来已久,从导航到规划再到辅助决策,时刻在展现着它的巨大功效。万维网改变了人类社会的各个方面,也正在改变地理信息系统。WebGIS这一新兴领域正是地理信息系统与万维网结合的产物。从1993年出现之后就不断地发展壮大,并以其独特的魅力和广泛的用途渗透到人们的生活中,吸引了越来越多的互联网用户。各个行业都直接或间接的与WebGIS建立了不可分割的联系。但是随着各行各业的WebGIS应用日益增加,大量重复的GIS开发工作也每天在被复制,因此WebGIS开发的效率亟待提高。本文基于对各个行业的WebGIS应用系统的不断探索和研究,提出了可支持多行业的WebGIS中间件的概念,并进行了体系结构设计,定义了相应的接口规范。作为中间件本系统可以供各行各业的WebGIS应用开发者使用。WebGIS开发者无需了解GIS底层的复杂操作,就可快速构建GIS应用,从而把重心放在对业务系统的研究和开发上,为用户提供了更好的使用体验。同时对于OGC标准的实现也尽绵薄之力。论文分析并研究了当前GIS二次开发平台所存在的不足和局限性,参考大量的体系结构设计,遵循接口设计规范和原则,设计实现了WebGIS中间件体系结构和接口规范。并将该中间件应用到实际铁路GIS领域,对系统的功能和性能进行了验证。具体工作内容包括:(1)对比分析现有WebGIS技术的优缺点,提出支持多行业的WebGIS中间件概念。设计了其体系结构,并定义了相应的接口规范。(2)对WebGIS中间件系统的数据库、系统总体结构、系统接口规范、系统层次等进行了详细的设计。(3)使用上述体系结构和接口规范初步实现了一个支持多行业的WebGIS中间件系统。(4)对本论文设计的中间件进行应用,验证了本论文所提出的系统的体系结构和中间件接口。实践证明,本论文所提出的WebGIS中间件系统加快了WebGIS应用的开发效率,减少了各个行业在进行WebGIS开发过程中的大量重复工作。系统小巧轻便、使用简单。同时本系统对于各个行业的行业相关的GIS功能和行业无关的GIS功能都有着良好的支持和较大的拓展空间,具备一定的理论研究意义和实用价值。
[Abstract]:Geographical information has been used for a long time, from navigation to planning to auxiliary decision-making, showing its great effect. The World wide Web has changed all aspects of human society and is changing the new field of GIS. WebGIS is the result of the combination of GIS and the World wide Web. Since its emergence in 1993, it has been developing and expanding, and has attracted more and more Internet users because of its unique charm and wide use. All industries are directly or indirectly linked to WebGIS. However, with the increasing of WebGIS applications in various industries, a large number of repeated GIS development work is being replicated every day, so the efficiency of WebGIS development needs to be improved. Based on the continuous exploration and research of WebGIS application system in various industries, this paper puts forward the concept of multi-industry WebGIS middleware, designs the architecture and defines the corresponding interface specification. As a middleware this system can be used by WebGIS application developers in various industries. WebGIS developers can quickly build GIS applications without knowing the complex operations of the underlying GIS, thus focusing on the research and development of business systems. For users to provide a better use of the experience. At the same time, the implementation of the OGC standard is also limited. This paper analyzes and studies the shortcomings and limitations of the current GIS secondary development platform, and designs and implements the WebGIS middleware architecture and interface specification by referring to a large number of architecture designs and following the interface design specifications and principles. The middleware is applied to the field of railway GIS, and the function and performance of the system are verified. The specific work includes: (1) comparing and analyzing the advantages and disadvantages of the existing WebGIS technology, and putting forward the concept of WebGIS middleware supporting multi-industry. This paper designs its architecture, and defines the corresponding interface specification. It defines the database, system architecture, system interface specification of WebGIS middleware system. The system level is designed in detail. (3) using the above architecture and interface specification, a multi-industry WebGIS middleware system. 4) is applied to the middleware designed in this paper. The architecture and middleware interface of the proposed system are verified. Practice shows that the WebGIS middleware system proposed in this paper speeds up the development efficiency of WebGIS applications and reduces a lot of repeated work in the process of WebGIS development in various industries. The system is small and light and easy to use. At the same time, the system has good support and large expansion space for the related GIS functions and the industry-independent GIS functions in various industries, and has a certain theoretical research significance and practical value.
