GIS与可视化SDM技术集成问题探讨

Discussion on Integration of GIS and Visual Interactive Spatial Data Mining

随着地理信息获取技术飞速发展 ,使得当前存储在空间数据库中的空间数据的深度和广度得到了前所未有的发展 .为了解决GIS目前面临的“数据爆炸但知识贫乏”的难题 ,在介绍GIS发展现状等相关问题、空间数据挖掘技术、可视化技术的基础上 ,分析了GIS中数据挖掘的过程、特点及其相关技术支持 ,探讨了可视化技术在GIS数据挖掘中的重要作用 .对GIS与可视化交互空间数据挖掘集成技术进行了初步的研究 ,分析阐述了GIS与SDM集成的必要性、集成模式和集成路线 ,提出了一个以GIS为中心的二者集成的体系结构 .

Geo-spatial data have become much easier to collect with the techniques for gathering geographic information developing rapidly. These techniques have created and are creating digital data in spatial database in which the capacity of data is increasing exponentially. This paper analyses the process, characteristics and technology of data mining in GIS, discusses the importance of geo-visualization in data mining, and studies the integration of GIS and visual interactive spatial data mining. Besides, the paper expatiates the mode and route for the integration and a system framework for the integration of GIS and SDM has been proposed.
