| Abstract: | This paper discusses the basic concepts and technology of geographic information systems （GIS）, data mining, and spatial-temporal data mining, and on the basis of which proposes an idea based on GIS to actualize spatial-temporal data mining and data fusion according to the characteristics of weather data of complexity and diversi- ty, diverse formats, different manifestations, huge amount of data and growth speed. The framework of its applica- tion in meteorological services is designed, which improves the utilization of meteorological data and the accuracy of meteorological services. |
