In some projects charged by our lab such as national 863 project - " crop planting management components based on weather analyse " , anhui provincial 95 key project - " agricultural meteorology disaster evaluation system base on gis in anhui province " and the project " small coal mine security management and decision system based on gis in anhui province " , this paper combines the theory and arithmetic of rough set with gis and data mining in idss , investiges the application of rough set theory to precision analysis of attribute data and logical operation in gis , analyzes the logical operation based on rough set ( logical union , logical intersection , logical complement , mixed logical operation etc . ) , so that it can give a method y to research the gis attribute data and the uncertainty of attribute data after superposition operator , so as to express the roughness and illegibility of attribute data more accurately 在完成试验室所承担的国家863项目“基于气象分析的农作物种植管理软构件” 、省95攻关项目“基于gis的安徽省重大农业气象灾害测评系统”和“基于gis的安徽省小煤矿安全管理决策系统”等项目中,将粗糙集理论和算法与gis 、智能决策系统中的知识发现等相结合,对粗糙集理论在gis属性数据和逻辑运算精度分析中的应用情况进行了研究,分析了基于粗集的gis逻辑运算(逻辑并、逻辑交、逻辑补、混合逻辑等) ,从而为研究gis属性数据及其叠加运算后属性数据的不确定性提供了一种方法,能比较准确地表达属性数据的模糊性和粗糙性。
