基于WebGIS平台的雷达拼图技术

Technology about composition of radar echo images based on WebGIS platform

使用江西及周边省份16部多普勒天气雷达数据,在江西省自动站实时数据服务平台上进行拼图处理,实现雷达拼图在WebGIS上的集成、显示和查询等功能。结果表明:Web-GIS雷达拼图具有地理信息分辨率高,交互性好,可以任意叠加雨量、温度、风场、地质灾害区域、中小水库、公路交通等其它要素场,以及显示出图时间快等优点,为短临预报分析提供了一个实时的雷达拼图业务系统。

According to 16Doppler weather radar data in Jiangxi and neighboring provinces,radar echo images on platform of AWS real-time data service in Jiangxi are composed with functions of information integration,elements display and data query etc based on WebGIS.The results show that there are some advantages of WebGIS radar composition,for instance geographic information with high resolution,friendly interaction,superpose the following element fields at will such as rainfall,temperature,wind,geological hazard region,small and medium-sized reservoirs,highway and traffic etc.It can also fast display all elements,which can provide a real-time operation system of the composition of radar echo images for short-impending prediction.
