The lunar elevation data provided by SchrutkaRechtenstamm supplemented by similar data near the limbs provided by Davidson and Brooks, were used to determine the equation of surface of the Moon as a sum of spherical harmonics including terms up to the eighth order. This equation was used to construct a contour map of the Moon. The same work was repeated for data provided by Baldwin which also were supplemented by the same data by Davidson and Brooks. The two maps have some basic similarities. After improving the equation of surface derived from Schrutkas data in a way that a homogeneous Moon with this equation of surface would also satisfy the conditions, f 0.633 Koziel, 1964, beta 0.0006267 Jeffreys, 1959, gamma 0.0002274 Jeffreys, 1961, a third contour map which seems to be more realistic than the previous two is derived.
