【摘要】：针对目前地面气象观测数据统计分析工作中存在的统计分析流程和方法未形成规范,数据表现形式单调、服务功能单一、交互能力较弱等问题,研究与开发了基于Flex和Web GIS的地面气象观测数据处理系统。本文介绍了国内地面气象观测数据处理系统及Web GIS系统开发现状,通过引入先进的RIA技术,构建RIA下的Web GIS体系结构;对系统进行了教全面的需求分析,进行了系统总体设计、详细设计和系统测试设计;最后利用面向对象的可视化编程语言并基于Web GIS平台开发出了具有集多种气象要素任意时段的查询检索、统计分析、专题图制作、数据产品制作和推送,以及后台管理等八个子系统构成的地面气象观测数据处理系统。所开发的系统利用全省87个国家地面观测站建站以来的观测数据,可对全省温、湿、风、气压、降水量及雷暴、雾、霾、雨凇、霜、大风等影响我省的灾害性天气和关系人民身心健康的高关注度天气事件开展序列汇编查询与统计分析,能基于网络的进行气象数据产品的定制、下载、推送等业务服务流程,以丰富、实用、客观的统计分析气象服务图型产品进行表达,减少用户对资料的二次处理。该系统的设计与进一步发挥地面气象观测资料在服务防灾减灾、服务社会经济发展中的基础支撑作用。
[Abstract]:In view of the problems existing in the statistical analysis of surface meteorological observation data, such as the process and method of statistical analysis are not standardized, the data form is monotonous, the service function is single, and the interaction ability is weak, etc.A surface meteorological observation data processing system based on Flex and Web GIS is studied and developed.This paper introduces the present situation of the development of domestic ground meteorological observation data processing system and Web GIS system, constructs the Web GIS system structure under RIA by introducing advanced RIA technology, analyses the requirements of the system, and designs the system as a whole.Detailed design and system test design. Finally, by using object-oriented visual programming language and based on Web GIS platform, the query retrieval, statistical analysis and thematic map making are developed with various meteorological elements at any time.The data processing system is composed of eight subsystems, such as data production and push, and background management.The developed system can use the observation data of 87 national ground observation stations in the province since the establishment of the station, and can be applied to the temperature, humidity, wind, air pressure, precipitation and thunderstorm, fog, haze, rime, frost of the whole province,Strong winds and other high concern weather events affecting disaster weather and people's physical and mental health in our province carry out sequence compilation, query and statistical analysis, which can be used to customize, download, push and other business service processes of meteorological data products based on the network.In order to reduce the secondary processing of the data, the product of meteorological service chart is expressed by rich, practical and objective statistical analysis.The design of the system and further play the role of ground meteorological observation data in the service of disaster prevention and mitigation, social and economic development of the basic support role.
