摘要
随着地理信息系统(GIS)软件的成熟,其空间信息分析、处理和展示能力日趋完善。利用空间数据挖掘等空间信息分析抽取手段进行空间规则发现并对这些规则进行规范化与形式化描述进而利用GIS进行可视化展现已成为一种趋势。本文研究了空间关联规则、分布规则、分类规则的形式化描述,并且给出了这些规则的可视化解释过程。
As the improvement of the Geographic Information System (GIS) software, the capability in spatial information analysis .handling and display is perfected gradually. It has become one kind of tendency that utilizes the way of analyzing and extracting spatial information,such as spatial data Mining,to discover spatial rules and describe these rules regularly and formally .furthermore utilizes GIS to visual expression. This paper has a research on formal description of spatial association rule,spatial distribution rule and spatial classification rule,and then elaborates the visual explanation process of the spatial rules.
