Abstract: The mathematic theory for uncertainty model of line segment are summed up to achieve a general conception, and the line error band model of ε_σ is a basic uncertainty model that can depict the line accuracy and quality efficiently while the model of ε_m and error entropy can be regarded as the supplement of it. The error band model will reflect and describe the influence of line uncertainty on polygon uncertainty. Therefore, the statistical characteristic of the line error is studied deeply by analyzing the probability that the line error falls into a certain range. Moreover, the theory accordance is achieved in the selecting the error buffer for line feature and the error indicator. The relationship of the accuracy of area for a polygon with the error loop for a polygon boundary is deduced and computed.
