摘要
GIS在城市地下管网中的广泛应用导致了管网数据库中数据量的急剧增长。为提高城市地下管网的管理水平,更好地从管网数据库中采集有价值的知识,将空间数据挖掘技术运用到地下管网GIS系统是一种行之有效的方法。介绍GIS和空间数据挖掘结合的必要性,分析了基于空间数据仓库实施空间数据挖掘的理论依据,给出了一个实用的城市地下管网GIS空间数据挖掘模型。该模型可有效地在管网GIS中实现挖掘功能,使GIS具备一定的智能化特征。
The wide use of GIS to the underground pipelines in city leads to the rapid increase ofthe data in pipelines databases. Applied the technology of spatial data mining to the GIS of city underground pipelines is an effective method that improve the management level of city underground pipelines, and collect valuable knowledge from pipelines databases. The necessity of combining GIS with spatial data mining is introduced, then the theory basis of the spatial data mining based on spatial data mining is analyzed, at last a practical model of spatial data mining used in GIS of underground pipelines is given. The model effectively complete the data mining function in pipelines GIS and make GIS has some intelligent characters.
