基于Silverlight的空气质量模型动态展示

摘要

传统B/S系统在模型数据展现中灵活性和交互性等方面的不足大大限制了模型数据的表达效果及运用.介绍了B/S架构下基于Silverlight技术的空气质量模型模拟结果动态展示方法,重点阐述了如何使用"插值"和"连续色"两种方法来增强Silverlight展示效果的技术过程.采用在空气质量模型领域广泛应用的CMAQ模型数据检验系统效果,与Windows下的专业CMAQ分析展示软件VERDI的展示结果完全一致;基于Silverlight的空气质量模型动态展示系统具有更好的用户体验效果及不受用户操作系统平台限制的优点.%The methods to present air quality model data based on traditional browser/server system have some weaknesses,such as the lack of flexibility and interactivity, which limit the application and presentation effect of model data.In order to improve the effect of dynamic display, this paper introduced and discussed Silverlight-based air quality model simulation result dynamic display system.Described especially the methods of “interpolation” and “continuous color” based on Silverlight,which could enhance the display impression.The system was used to dynamically display the output data of CMAQ which was recommended by USEPA and widely used in the air quality simulation field.The displaying map created by the system is the same as that by VERDI, which is professional in analyzing and displaying CMAQ output data on the Windows platform.Silverlight-based air quality model dynamic display system has the advantages of better user experience and non-platform limited,which means that it can be used on both Windows and Linux only if the platform has Internet browser.
