The most important sources of information useful for positioning features on the surface of the Moon have been telescopic pictures; Lunar Orbiter pictures; Apollo 15, 16, and 17 mapping camera frames; and the Soviet Zond 6 and 8 pictures. This Note describes the combining of the Apollo mapping frames, telescopic pictures, and Mariner 10 pictures into a unified control network of the near side of the Moon with its origin at the center of mass. New coordinates of 1,156 points in the network are given, as are ten points from a Mariner 10 solution in the north polar region. The Lunar Orbiter and Zond 6 and 8 pictures must eventually be tied to the Apollo and telescopic networks to obtain a far-side control network in the same coordinate system.
