冬奥气象图形产品可视化模型研究

Research on Visualization Model of Meteorological Graphic Products in Winter Olympic Games

高质量图形产品是冬奥气象服务信息的重要载体。基于冬奥气象数据高时空分辨率特征,研究了由多维气象信息向制图要素转换的冬奥气象图形产品可视化概念模型;设计了由基于数据引擎的结构映射、赛事服务的空间映射、组件应用的元素映射和派生思想的属性映射组成的冬奥气象图形产品可视化过程模型。针对差异化、准实时气象服务制图需求,设计了基于DVDL可视化描述语言的制图表达框架,对可视化模型进行业务组织,研发了冬奥气象图形产品加工系统,提供50余种基础产品样式和所见即所得的制图编辑功能,支持任意位置点长时间序列气象产品、山地赛场三维气象产品和多赛区综合服务气象产品的制图渲染。成果在2022年北京冬奥会气象服务中应用,生产了200余种不用服务主题气象图形产品,后续也可为其他冬季赛事和重大活动气象服务保障提供精细化产品制作解决方案。

High quality graphic products are an important carrier of meteorological service information for the Winter Olympics.Based on the high spatiotemporal resolution characteristics of Winter Olympics meteorological data,a conceptual model for visualizing Winter Olympics meteorological graphical products by converting multidimensional meteorological information into mapping elements was studied.A Winter Olympics meteorological graphical product visualization process model was designed consisting of structural mapping of the data engine,spatial mapping of event services,element mapping of component applications,and attribute mapping of derived ideas.In response to the demand for differentiated and quasi real-time meteorological service mapping,a mapping expression framework based on DVDL visualization description language was designed.The visualization model was organized for business,and a Winter Olympics meteorological graphic product processing system was developed.It provides more than 50 basic product styles and rich mapping editing functions,supporting long-term series meteorological products at any location Cartographic rendering of three-dimensional meteorological products and comprehensive service meteorological products for multiple competition areas in mountain sports venues.The results were applied in the meteorological services of the 2022 Beijing Winter Olympics,producing over 200 unserviceable themed meteorological graphic products.In the future,it can also provide refined product production solutions for meteorological service support for other winter events and major events.
