The Preprocess Method of Spatial Information Based on Rough Set
基于粗糙集的空间信息预处理方法

The spatial data may be extracted by different methods. But the original data cannot be applied to applica- tion directly,it need to be pretreated. This paper gives the research on the common course of pretreatment of spatial information,and presents several pivotal problems in pretreatment. The problem of complementarity of missing value and discrete of attribution can be resolved through the theory of Rough set applied to pretreatment of spatial data,and the according algorithm is presented as well.
