Whitaker, Kuiper, Hartmann & Spadley: Rectified Lunar Atlas (1963)

(glossary entry)


As part of G. P. Kuiper's Moon-mapping program of the late 50s and 60s a unique atlas of the limb regions was made, the Rectified Lunar Atlas by Whitaker, Kuiper, Hartmann and Spradley. This large format, bound atlas showed each limb area as seen from directly overhead. Since this was made before lunar orbiters flew it was necessary to create it by projecting telescopic images of the Moon onto a large white sphere and then rephotographing the sphere from directly over the area of interest. In doing this Bill Hartmann discovered the multi-ring structure of Mare Orientale and other basins. This vertical view also allowed us crater catalogers (compiling the System of Lunar Craters) to clean up many inconsistencies of limb nomenclature and recognize craters deserving names. D.W.G. Arthur and E.A. Whitaker gave 68 new names or shifted earlier names to real formations in the Atlas. Information from personal experience and (Whitaker, 1999, pp. 234-5). - tychocrater Jul 28, 2007

Additional Information

  • The atlas consists of 30 fields of 30x30° each illustrated on 30x38 cm sheets. Each field is shown with at least three illuminations (waxing, Full Moon, and waning) and accompanied by a gridded line drawing identifying the features.
  • D.W.G. Arthur presented a report on nomenclatural changes introduced in the Rectified Lunar Atlas work, which was approved at the 1964 IAU meeting.
  • The idea of rectifying lunar photographs by projecting them onto a globe seems to have been pioneered by Dr. F. E. Wright, who recorded the data directly with a photographic emulsion on the globe. Alter and Roques (1955) photographed Wright's globes from overhead the features of interest, and (according to the North American Atlas) in areas where Wright's globes had insufficient detail photographed new images projected onto a white wooden sphere.
  • According to Carder (1962), the DMA had facilities for rectifying images by projection onto a sphere independent of those at the LPL.
