This map is a long time coming. The only truly accurate readings of lunar elevation have come from satellite readings but these were never complied together to make a complete map. In the past there have been a couple atlases claiming to have elevations marked, like the 1969 Times Atlas of the Moon, but these were guesstimates and in many cases out right lies created in part to deceive the Soviets. Until recently, some of the most accurate lunar elevation measurements were done by an amateur astronomer using his own telescope and CCD camera.
