摘要
论述了地理信息系统、数据挖掘、时空数据挖掘的概念和技术方法。在此基础上,针对气象数据具有来源复杂、种类繁多、格式多样、表现形式各异、数据量大和增长速度快等特点,提出了基于地理信息系统进行时空数据挖掘和数据融合的设想,并根据各自优势将三者进行集成并设计了其在气象服务方面的应用框架,提高了气象数据的使用率和气象服务的准确率。
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.
