This paper presents a method for estimating the model error, specifically, a truncation error, of lines. The generic method for describing truncation error for n-dimensional spatial features is developed first based on the numerical analysis theory. The methods for describing truncation error of the lines in three-dimensional and two-dimensional space, which are the two frequently used cases, are then derived as special cases of the generic method. This research is a further development of earlier work on line error modelling, which were mainly focusing on the propagated error rather than model error.
