This new work represents a seamless, globally consistent, 1:5,000,000-scale geologic map derived from the six digitally renovated geologic maps (see Source Online Linkage below). The purpose of this task was once to create a digital useful resource for science lookup and analysis, future geologic mapping efforts, be it local-, regional-, or global-scale products, and as a useful resource for the educators and the public involved in lunar geology. Here we current the executed mapping undertaking as unit contacts, geologic unit polygons, linear features, and unit and function nomenclature annotation. The product overlies shaded-relief merchandise derived from SELENE Kaguya terrain digicam stereo (equatorial, ~60 m/pix) and LOLA altimetry (north and south polar, a hundred m/pix). These statistics are now not covered with this download due to measurement considerations, however, a readme in the "Lunar_Raster" folder affords the download links. This download web page consists of a PDF of the geologic map (right side) with a Short Description of Map Units and Explanation of Map Symbols, as properly as a JPG of the map for rapid gets entry to viewing. This launch is a situation to replace primarily based on neighborhood comments and peer-review.

Version two updates:

Two blunders have been addressed in this update: (1) Large vicinity polygons had been offset from their contacts, in all likelihood due to consumer error. Polygons had been rebuilt to restoration the difficulty and submit processing (dissolving, reattributing, etc.) to rectify the aesthetic of the map. (2) Contacts have been now not seen however ought to have been due to flawed labeling as DND (do now not draw). Those that wanted to be drawn have been reattributed as "certain" these that are now not drawn are labeled as "internal". Additionally, in model 1 of this data, crater polygons with comparable attributes had been dissolved and lumped into contiguous units. This has been modified so that all craters are now discrete units. This provides ~1000 devices to the GeoUnits feature class. Their contacts are now seen and labeled as "certain".
