“The first contour map of the Moon was constructed by Franz (1899) Just before the turn of the century. He employed only 55 points, a number not too low when sufficiently accurate, or when expectations are not exceeding the possibilities. He worked with linear interpolation between the known points, a rather poor technique for the present and in this particular case.” C.L. Goudas: A contour map of the Moon. Oct 1964. Mathematical Note No, 369 Mathematics Research Laboratory, BOEING SCIENTIFIC RESEARCH LABORATORIES.
