WebGIS与基于网络的数据挖掘整合应用研究

Integration of WebGIS and data mining based on internet

数据挖掘为我们提供了一种从海量数据中发现潜在知识的技术手段,将数据挖掘技术应用到GIS能提升GIS对数据的分析能力,从而提高决策支持水平。WebGIS是传统GIS的网络化延伸,目前WebGIS的空间分析和决策支持能力都较低,将基于网络的数据挖掘和WebGIS结合能有效加强WebGIS的分析能力。本文对WebGIS和基于网络的数据挖掘的结合进行了探讨,提出了两者整合应用的模型。

Data mining, a useful method to discover knowledge from data, can be applied to GIS in order to enhance its analysis a-bility . WebGIS is an extension of GIS, but the ability of spatial analysis and decision support is rather poor now. If data mining based on internet and WebGIS are integrated together, we can effectively enhance the ability of analysis of WebGIS. This paper focuses on the integration of DM based on internet and WebGIS and proposes the models of the integration.
