【摘要】：台风是世界上最具破坏力的气象灾害之一，我国是一个多台风国家，特别是沿海地区每年都会因为台风而遭受巨大的经济损失和人员伤亡。近年来随着气象科学的飞速发展，收集台风数据的手段越来越先进，使得台风数据量急剧增加。同时，随着计算机软件技术的发展，基于地理位置的移动信息服务也越来越普及，人们对地理信息的关注度也越来越高。故而，寻求一种高效的数据收集、管理、分析和共享的地理信息平台有着迫切的必要性和现实意义。传统的GIS系统虽然具备数据收集、处理、管理、分析等功能，但是其具有诸多局限性。比如需要在客户端配置复杂的环境同时需要具备一定的GIS软件应用能力的工作人员才能顺利使用GIS系统。WebGIS是Internet和GIS的结合体，它不仅具有传统GIS的所有功能，同时还可以实现地图服务发布和共享。WebGIS将一个只有少数专业人士使用的GIS系统转变成了一个可以供大众通过Web浏览器就可以使用的信息查询平台。它不仅很大程度上实现数据共享同时将GIS应用推向了更广阔的天地。本论文在深入研究台风信息查询系统的功能需求以及台风数据特征的基础上，提出了构建基于WebGIS的台风信息检索系统的解决方案。研究内容主要包括WebGIS的模型结构与各种实现技术的比较，，ArcGIS Server体系结构、服务器管理模式以及其系统的各个组成部分，台风信息的数据形式、空间数据模型、采用空间数据引擎ArcSDE为GIS数据与Oracle数据库通道等内容。基于这些研究探讨最终确定了适合本系统的开发平台、系统三层结构以及开发方法。本系统采用了ArcGIS Serverfor java ADF进行开发，ADF是Esri公司为开发WebGIS提供的一套框架，采用该框架，开发人员可以将更多的精力集中于核心功能的开发上。论文的研究成果在于，提出了基于WebGIS的台风信息检索系统的解决方案，并开发了其原型作为验证。在该原型中实现了台风信息系统的基础功能和核心功能，比如地图放大、缩小、漫游、测距以及台风路径的显示等。同时运用了ArcGIS Server提供的AJAX技术支持，避免了地图操作过程中的白屏现象，拥有良好的用户体验；比较分析了台风路径显示的若干技术，最终确定采用VML技术实现了台风路径显示的动画效果。
[Abstract]:Typhoon is one of the most destructive meteorological disasters in the world. Our country is a multi-typhoon country, especially the coastal areas will suffer huge economic losses and casualties because of typhoon every year. In recent years, with the rapid development of meteorological science, the means of collecting typhoon data is more and more advanced. At the same time, with the development of computer software technology, mobile information services based on geographical location are becoming more and more popular, and people pay more and more attention to geographical information. Therefore, it is of urgent necessity and practical significance to seek an efficient geographic information platform for data collection, management, analysis and sharing. Although the traditional GIS system has the functions of data collection, processing, management and analysis, it has many limitations. For example, in order to use GIS system. WebGIS is a combination of Internet and GIS, it not only has all the functions of traditional GIS, but also needs the staff with certain ability of GIS software application to configure complex environment on client side. At the same time, it is possible to publish and share map services. WebGIS transforms a GIS system used by a few professionals into an information query platform that can be used by the public through the Web browser. It not only realizes the data sharing to a great extent, but also pushes the GIS application to a wider world. On the basis of deeply studying the functional requirements of typhoon information query system and typhoon data features, this paper proposes a solution to the construction of typhoon information retrieval system based on WebGIS. The research contents mainly include the comparison between the model structure of WebGIS and various implementation technologies, the architecture of ArcGIS Server, the management mode of server and the components of its system, the data form of typhoon information, the spatial data model. The spatial data engine ArcSDE is used as the channel of GIS data and Oracle database. Based on these studies, the development platform, the three-tier structure and the development method of the system are finally determined. This system adopts ArcGIS Serverfor java ADF to develop ADF is a set of framework provided by Esri Company for developing WebGIS. With this framework, developers can concentrate more on the development of core functions. The research results of this paper are as follows: the solution of typhoon information retrieval system based on WebGIS is put forward and its prototype is developed as verification. In this prototype, the basic functions and core functions of the typhoon information system are implemented, such as map amplification, reduction, roaming, ranging and typhoon track display. At the same time, it uses AJAX technology support provided by ArcGIS Server to avoid the phenomenon of white screen in map operation, and has good user experience. Finally, VML technology is adopted to realize the animation effect of typhoon track display.
