空间数据挖掘及其在3S集成系统的应用研究

Spatial Data Mining and Its Application in 3S Integrated System

数据挖掘作为一项从大量数据中获取有用知识的实用技术,已广泛应用于各行各业并取得了巨大的经济和社会效益,而其在3S集成系统的应用也具有巨大的潜力。文中概要介绍了数据挖掘技术的理论、过程及方法,将其扩展到空间数据库的基础上进行探讨,总结出空间数据挖掘的一般常用规则及方法,并提出其挖掘模型,最后给出其在3S集成系统中的应用实例,结果表明其对空间环境分析、虚拟仿真显示、决策智能支持具有重要基础意义。

Data mining,as an available technique to get useful knowledge from mass data,is widely used in many different fields and has created great economic and social benefit.It also has very large potential in 3S system field.This paper in general introduces data mining from its theory,operation process,and methods.Then describes these based on spatial databases,finally it gives an application example in 3S integrated system,also the author analyzes and summarizes the system.The result indicates that the technology is very useful to analysis of spatial environment,the display of virtual simulation and the sustainment of decision-making.
