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. %K Data pretreatment %K Spatial data process %K Rough set application %K Complementarity of missing vatue %K Discreteof attribution
