基于3D GIS的福建省人工影响天气指挥系统设计与应用

Design and Application of Fujian Weather Modification Command System Based on 3D GIS

基于3DGIS和移动互联网技术,对接人工影响天气“五段业务”,设计了省、市、县三级通用、上下协同的2D、3D一体化、B/S架构的福建省人工影响天气指挥系统。系统建立了集约化的全省人影数据库及功能流程,融合应用多源气象观测资料,自动识别作业云体进行作业点条件预警,直观展示全省作业动态并提供导航,实现了实时决策指挥和高效信息交互;利用雷达基数据3D反演及外推技术,在GIS平台上叠加显示3D云团与作业点安全射界,实现作业方案自动设计与3D模拟修订;通过移动通讯终端App自动采集相关数据,实现人影作业信息的快速规范上报与审核入库。系统界面友好,交互性强,有效提升了人影协调指挥能力和科学决策水平。

Based on the technology of 3D geographic information system(GIS)and mobile internet,Fujian artificial weather modification command system(B/S,2D and 3D integrated)was designed to satisfy the“five-stage business”,which was universal at the provincial-municipal-county level.Intensive database and function flow of the whole province were also established.By using multi-source meteorological observation data,the system could mainly identify target-cloud automatically for early warning of operation point conditions.Dynamic artificial weather modification operation of the whole province and real-time navigation were visually displayed,and real-time decision-making command and efficient communication between the command center and operating points were realized.Operation parameters were automatically designed and 3D simulated to test and revise by the combined use of layer overlap analysis technique,automatically identified safe area information of operation point,3D radar-based data inversion and extrapolation technology,which was based on 3D GIS platform and 3D visualization technique.Also,information of weather modification operation was in the position to be reported and audited normatively and rapidly by means of App automatically gathering relevant data.The system had friendly interface and strong interaction,which effectively improved the ability of artificial weather modification command and the level of scientific decision-making.
