This paper describes the error problem of Boolean logical operations for categorical data of GIS non spatial associated attributes and analyses the error spread and the precision for Boolean logic operators: AND, OR and NOT.

• 本文对GIS属性类别数据进行逻辑运算的误差问题进行了研究，并且针对逻辑运算的“逻辑交”，“逻辑并”和“逻辑补”（或逻辑差）等算法的误差传播和精度问题进行了分析
