With the human activities and the development of nation-building, increasing demand for meteorological increasingly highlight the importance of meteorological losses caused by meteorological disasters on the national production and life is also very serious. Network of meteorological services of the public in order to improve the meteorological service quality, reduce and prevent the loss of meteorological disasters become an important direction of development, geographic information systems and meteorological services combining the development trend of WebGIS become an important issue. Based on the ArcMap and VML technology WebGIS Vector model can be integrated on the one hand to the Bureau of Meteorology's information management, improve the efficiency of office automation, reduce the human factor, reducing the cost of weather information dissemination, to facilitate other hand, for the life of the general public, to the decisions of the national party and government departments provide reliable auxiliary services, distribution of meteorological early warning information, thus preventing the hazards of meteorological disasters, and reduce the economic losses of property and personnel casualties. This topic first analyzes from home and abroad WebGIS development and research status quo, needs to collect a variety of weather information services network affordability and efficiency research, design WebGIS Vector model. Then vector generation, as well as the conversion of latitude and longitude coordinates to screen coordinates. In the the Vector background layer formed on the basis of the analysis of meteorological services, weather service information drawn using VML technology, combined with a scripting language for vector space operations and geographic information visualization of meteorological information, the framework of a model system . Focuses on WebGIS technology and VML graphics technology, and conducted in-depth research on WebGIS technical difficulties, and provide the appropriate solution, WebGIS Vector model. Then, according to the characteristics of the Vector Markup Language VML geospatial information and meteorological information service union query. VML's unique mark in the the VML drawing module, automatic weather site rendering, as well as the meteorological ground elements of the query, the last client and server-side scripting language to dynamically interact with data. Finally, the actual use of the service network in Xiamen Meteorological Bureau of model validation, combining geospatial information and meteorological information, geospatial information incremental Metafile Vector solve geographic information network transmission efficiency, geospatial coordinates to the Cartesian coordinate plane, and ultimately the meteorological information services function. Design framework based on a model system, the practical application show that the effectiveness and feasibility of the model of WebGIS Vector.
