Research on Visualization Model of Meteorological Graphic Products in Winter Olympic Games
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 mete-orological graphic products.In the future,it can also provide refined product production solutions for meteorological service support for other winter events and major events.
