Unified Geologic Map of the Moon

A new unified geologic map of the Moon, based on digital renovations that updated 1970s-era geologic maps to match more recent topographic and image data gathered by lunar orbiters, was released by the USGS last month. The map is “a seamless, globally consistent, 1:5,000,000-scale geologic map”; the paper version (25 MB JPEG) provides azimuthal projections beyond the 55th parallels and an equirectangular projection between the 57th parallels.

Previously: Lunar Geology and the Apollo Program.

Update, 22 April 2020: Version 2 of this map was released in March to address a number of errors in the first version.
