为了建立数字校园信息平台,必须对校园GIS数据进行分析和挖掘。文中提出将校园GIS与数据挖掘系统进行集成,空间数据库系统负责空间信息抽取,GIS实现对挖掘结果进行可视化显示。搭建一个空间数据挖掘原型系统模型,利用设计的挖掘算法,挖掘出空间数据库中隐含的知识,并将空间数据挖掘结果进行可视化输出。该原型系统已成功应用于某高校校园GIS,不仅可以挖掘显示知识(校园每个教学楼的上座率),还可以发现隐藏在校园GIS中的隐式知识,是对现有空间数据挖掘系统的有益改进和补充。

In order to establish a digital campus platform,the campus GIS data must be analyzed and mined. The campus GIS and digital mining system is intergrated,the spatial database system for the extraction of spatial information,and SDM for the visual display of min-ing results. A spatial data mining prototype system is constructed,which can discover the implicit knowledge inside spatial database using the designed data mining algorithm. The prototype system has applied into a campus GIS,it not only discoveries the explicit knowledge but also implicit knowledge hidden in the campus GIS,so that it is a beneficial improvement and complement for present spatial data min-ing prototype system.
