Some methods for contour mapping by means of a digital plotter are dicussed, and a new method is presented that is simple enough to be implemented by programs with a rather small number of instructions (about 120 FORTRAN IV instructions are required). Comparisons with some methods proposed by other authors are also performed. A FORTRAN IV program implementing the proposed method is availabel at the Istituto di Elettrotecnica ed Elettronica, Politecnico di Milano.
