三维气象GIS平台关键技术研究与实现
|
摘要
针对三维GIS的发展应用以及气象服务对于高效决策和直观可视性的要求,开发了具有自主知识产权的三维气象GIS平台。本文从体系结构、功能、数据访问及组件方面介绍了系统的设计方法,并详细论述了平台的关键实现技术,包括气象数据组织、气象标绘、二维图层和三维体绘制技术。该系统能够高效加载海量的二三维气象数据,并支持气象标绘和分析等功能。该系统运行稳定,可视化效果突出,为气象数据处理、数值预报、气象模拟仿真等气象服务搭建了一个坚实的三维基础平台,具有重要的应用价值。
Concerning the development of three-dimensional GIS application and the higher demands in visualization of meteorological service in the efficient policy-making support,a method of developing threedimensional meteorological GIS with independent intellectual property rights is presented.A description is made from the design of system,functions,data accessing,components,and the implementation technology of meteorological data organization,meteorological plotting,and 2Dand 3Dmeteorological data drawing.The system can efficiently load massive two-dimensional and three-dimensional meteorological data,and support meteorological plotting,analysis,and other functions.The platform runs steadily and has outstanding visual effect.It is useful for meteorological data process,numerical weather prediction,meteorological simulation and other meteorological services.
