Abstract: The mathematical formulas for the estimation of dinitizing errors along curves in a cartographic map have been derived by means of the difference operator and time-sequential analysis. Numerical examples presented in the paper show how to use the formulas to estimate the digitizing errores after having a set of digitizing data for curves.
