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 threedimensional 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 2D and 3D meteorological 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.
