Firstly,the paper introduces the basic conception of rough set,and combines the importance of attribute data and common weight analysis methods in GIS together.Then,it presents a new method for weight confirming in GIS data analysis based on the theory of Rough Set.Comparing to traditional methods of confirming weight in multi-factors,the new method presented in the paper is based on the data self-adapting,and does not need intervene humanly.Therefore,the method is intelligent and efficient.
