This is the third part of a series of papers that proposes a method to estimate precision of spatial information. This paper deals with the method how to estimate precision by overlaying some kinds of spatial information. First, the model presented in part 1 and 2 is modified. Then a method to estimate standard deviation by overlaying some kinds of spatial information is introduced. Finally the model is applied to a case in which position error generated by map overlay is examined.
