As WebGIS has many shortcomings in publishing mass meteorological data, GIS technology is applied to meteorological data processing. Considering the characteristics of meteorological data, GIS is a good tool to publish mass spatial meteorological data efficiently. To publish grid meteorological data, a flexible and efficient constructing algorithm using the image pyramid model is adopted, combined with the method of generating tiles dynamically on the server, which aims at reducing I/O operations and resampling calculation. Besides the publishing of vector meteorological data, the multi level display of data from various stations and the publishing and sharing on the Internet of mass meteorological information are realized satisfactorily. The application proved that by this way, map data can be processed and published very fast, which can provide references for the follow up development of the meteorological GIS platform.
