新一代天气雷达业务化系统地图设计及模式应用

天气雷达回波需要与地理信息融合应用,以定位雷达回波,指导气象服务。本文针对新一代天气雷达业务化系统(ROSE)产品显示子系统,设计了全新的开放地图格式,采用全国一份地图数据文件,各地雷达站点动态匹配的方式,改进了现有雷达业务系统中主用户处理系统(PUP)需要各个站点分别申请定制地图的不便。ROSE产品显示子系统支持多种型号业务雷达数据在不同地球投影方式下的地图自适配显示。地图应用子模块程序设计中引入设计模式,有效解决了精细化地图数据的显示效率问题,实现了显示信息与速度的平衡。

Map Design and Pattern Application of Radar Operational Software Engineering System

Weather radar echoes need to be fused with geographic information to locate radar echoes and guide meteorological services. The Radar Operational Software Engineering (ROSE) has designed a new open map format and adopted one document with national map data to dynamically match radar stations. This method improves the inconvenience that the Principal User Processor (PUP) system needs each site to apply for customized maps in the existing radar service system. The ROSE product display subsystem supports the map adaptive display of various weather radars and their data under different earth projection modes. The design pattern is introduced into the program design of the map application submodule, which effectively solves the problem of display efficiency of refined map data and realizes the balance between display information and efficiency.
