The development and construction of meteorological service systems are the foundation to achieve a high quality meteorological service. According to the lagging situation of the meteorological service system, based on the characteristics of meteorological service, three dimensional geographic information system （3DGIS）technology is applied to the construction of a meteorological service system, Global Weather Analysis Service System (GWASS). GWASS can satisfy the processing and analyzing of meteorological information based on GIS, and aid the meteorological service product making, displaying, and outputting, which provides a basic platform for meteorological service and performs well in application. The design and implementation of GWASS are introduced; the overall architecture design and hierarchical design, as well as the functions and effects of the core subsystem and functional subsystems, are described based on Microsoft “.net” platform; and the key techniques of 3DGIS applied to weather service are analyzed. An application example of GWASS is given.
