基于RIA的WebGIS自动气象站数据服务系统

WebGIS Automatic Weather Station Data Service System Based on RIA

针对自动气象站实时数据分析与显示的实际需要,采用基于RIA的WebGIS技术进行了自动站数据服务系统的开发与实践,实现了自动站实时数据的实况监测、动态展现、等值面绘制、组合检索查询等功能.运行结果表明:该系统模型数据结构简洁,数据交互效率较传统WebGIS有明显提高,用户体验感强,为气象监测、预警预报提供了高效集约的自动站实时数据支撑服务.

To meet the demand of analysis and display realtime weather data from automatic weather station （ AWS for short）, an application of WebGIS technique based on RIA （ Rich Internet Applications） has been developed for AWS data service. It implemented the f-unction of AWS data live monitoring, dynamic display, combination query and isosurface r-endering. After running the applietion for a period of time, it was proved that the application had reasonable data structure, more efficent data interaction than traditional WebGIS and better user experience. This application provides highly efficient and intensive data support for weather monitoring, weather forecast and early warning.
