【摘要】：随着公众对气象信息关注度的提高以及气象观测设备的增强,气象部门累积的气象产品数量越来越多,种类也越来越丰富,如何将这些信息整合并及时让公众获取是目前气象服务领域亟需研究的问题。同时,随着信息获取渠道的日渐丰富,越来越多的用户选择从网络上获得气象信息,因此,气象信息的网络发布成为气象服务中不可或缺的一部分。如何将这些气象产品快速且形象地展示给公众,也是气象信息发布需要研究的另一内容。另外,目前的气象信息网站在人机交互、反应速度等方面仍存在欠缺,如何解决这些存在的问题,提高用户的体验,也是论文需要解决和研究的内容。针对以上问题,本文提出一种基于WebGIS和Flex架构的面向公众的气象信息发布方法。该方法结合WebGIS展示信息形象具体和FleX反应速度快、用户体验性好的优点,并结合WebGIS最新使用的REST(Representational State Transfer,表述性状态转移)架构风格,形成了一系列从数据处理、数据展示到地图查询的面向公众的气象信息处理方法。本文的主要工作和创新点如下： (1)结合WebGIS技术和Flex技术的优点,将其运用在气象信息网络发布中,总结出一套适用于气象信息发布领域的、新颖的、高效的气象信息发布方法。 (2)将该方法应用在实际的气象发布系统设计中,设计并实现了嘉定区气象灾害预警信息系统,并在实际业务中已投入使用。较之传统的气象信息发布系统,在反应速度、用户界面、用户体验等各方面都具有明显的优势。 (3)针对气象信息整合和发布中存在的一些关键问题,研究并实现了包括气象数据的实时获取和更新、气象数据的空间化表达、基于REST架构的WebGIS及运用瓦片技术生成地图等技术。较之传统的WebGIS,所提供的地图服务更丰富灵活、服务重用性更高、更节省服务器资源,更适用于灵活多变的气象领域。
[Abstract]:With the increasing attention of the public to meteorological information and the enhancement of meteorological observation equipment, the number of meteorological products accumulated by meteorological departments is increasing and the variety of meteorological products is becoming more and more abundant. How to integrate this information and make it available to the public in time is an urgent problem in the field of meteorological service. At the same time, with the increasing enrichment of information access channels, more and more users choose to obtain meteorological information from the network. Therefore, the network release of meteorological information has become an indispensable part of meteorological services. How to display these meteorological products to the public quickly and vividly is another issue that needs to be studied. In addition, the current meteorological information website in the human-computer interaction, reaction speed and other aspects are still lack, how to solve these problems, improve the user's experience, is also the need to solve and research the content of the paper. In order to solve the above problems, this paper presents a method to publish meteorological information for the public based on Web GIS and Flex architecture. This method combines the advantages of concrete presentation of information image in WebGIS, fast response speed of Flex and good user experience, and combines with the architecture style of representation State transfer, which is newly used in WebGIS, to form a series of data processing. Public-oriented meteorological information processing method for data display to map query. The main work and innovations of this paper are as follows: (1) combining the advantages of WebGIS and Flex technology, the paper applies them to the meteorological information network publishing, and summarizes a set of novel ones, which are suitable for the field of meteorological information release. This method is applied to the design of actual meteorological release system, and the early warning information system of meteorological disaster in Jiading district is designed and implemented, and it has been put into use in actual operation. Compared with the traditional meteorological information publishing system, it has obvious advantages in response speed, user interface, user experience and so on. The research and implementation include the real-time acquisition and updating of meteorological data, the spatial representation of meteorological data, the Web GIS based on rest architecture and the use of tile technology to generate maps. Compared with the traditional WebGISs, the map services provided are more flexible, more reusable, more saving server resources, and more suitable for the flexible and changeable meteorological field.
