摘要
在现有的多种点目标综合方法的基础上,提出了利用基于粗集理论的分类思想对GIS中的点群目标进行综合的方法。分析了粗集分类思想与GIS综合之间的关系,从理论基础到方法应用两方面阐述了两者的共同点及运用粗集方法进行GIS综合的可行性。具体介绍了运用粗集方法进行点目标综合的方法和步骤,并进行了实验分析。
On the basis of the existing methods of point object generalization, and in view of the inadequacy of existing methods, a rough set idea to resolve the problem of point object generalization is put forward. After analyzing the relationship between the classification thinking of rough set and GIS generalization, the feasibility of using rough set method to generalize point object in GIS is explained. The methods and steps of generalizing point object with rough set method are introduced; and the experiment is analyzed.
