摘要
随着现代科学技术的迅速发展,复杂多变的空间数据日益膨胀,远远超出人们的解译能力,迫切地需要数据挖掘和知识发现为其提供知识。文中从空间数据挖掘的基本概念出发,详细阐述了空间数据的特点、空间邻接关系及其相关操作,并针对空间邻接关系给出了几种典型的空间数据挖掘方法。
With the application and development of modem science and technique, the tremendous amotmts of spatial and non - spatial data have been stored in large spatial database （SDB）. These are far beyond the human ability to interpret and analyse of them, which is badly in need of spatial data mining（SDM） to provide knowledge. From the basic conceptions of SDM, introduces characteristics of spatial data, spatial neighborhood relation and its operation. Also discusses typical spatial data mining methods based on spatial neighborhood relation.
