Geologic Map of the Apennine-Hadley Region of the Moon, Apollo 15 Pre-Mission Map Renovation, 1:50K and 1:250k, 2022

The original geologic maps of the Apennine-Hadley region (I-723) were published in 1971 as two map sheets (1:250,000 and 1:50,000) in a Transverse Mercator projection to support the Apollo 15 mission, the fourth crewed mission to land on the Moon (July 26 – August 7, 1971). These renovated versions of the 1:50k and 1:250k maps represent a best effort to capture and preserve the fidelity of the original mapping effort in an interactive digital format. These maps are not updated versions or reinterpretations of the original geologic maps which were based on Lunar Orbiter images, but spatial adjustments to a Lunar Reconnaissance Orbiter (LRO) Wide Angle Camera (WAC) basemap to make the maps more compatible with current digital datasets [...]
