The Lunar and Planetary Institute (LPI) has created a digital version of the Lunar Orbiter Photographic Atlas of the Moon, published in 1971 and considered "the definitive reference manual to the global photographic coverage of the Moon." The site includes all 675 plates contained in the original work, digitally enhanced to increase photo quality. Visitors can view images by feature name, listed alphabetically or by descending latitude and longitude, or they can search by feature name, photo number, or coordinate range. Returns include a large thumbnail image, photo number, feature name, latitude and longitude, size, sun angle, spacecraft altitude, and medium photo center latitude and longitude. Students and general users may wish to consult the even easier to use Consolidated Lunar Atlas, which allows browsing by a long list of plates, thumbnails, or even better, an interactive image map.
