Digitized Lunar Orbiter IV Images: A Preliminary Step to Recording the Global Set of Lunar Orbiter Images in Bowker & Hughes

Introduction: The “Lunar Orbiter Photographic Atlas of the Moon” by Bowker and Hughes is the definitive reference guide to Lunar Orbiter global coverage of the Moon. However, the atlas is out of print and almost impossible to find. This resource has a big demand within the lunar science community. The catalog contains 675 images, with low to moderate sun-angle, for study of lunar surface features. Scientists without a copy of the atlas must reside in close proximity to an Regional Planetary Imaging Facility (RPIF) or other planetary data facility with a copy of the atlas. Thus far, we have digitally archived the complete set of Lunar Orbiter IV mission images covering the Moon’s near side. Our goal is to digitize the complete set of images contained in Bowker and Hughes by the end of 1999.
