The story of how National Geographic’s iconic 1969 map of the Moon — the first complete map of the Moon — was made is recounted, with considerable digression, by retired cartographer Richard Furno, who worked on the project, on Kelso’s Corner: part one, part two. The real challenge was the far side: the work involved in taking photographs from lunar orbiters, plotting them on a globe, and then creating a hemispheric map cannot be underestimated. Via Kottke.
