The end result is a summarized geologic map rather than a precise replication of the original data. The map features are colored only by geologic category (craters, basins, etc.) and not by age. I thought it was too complicated to show all these uncertain aggregations in one map, so I decided to omit timescale data entirely. And some geologic categories combined many time periods, like craters from Imbrian, Nectarian, and pre-Nectarian time periods. Some areas were described with uncertainty - like plains from the Imbrian or Nectarian era. This moon data was also challenging because the geologic timescales weren’t very precise. So I decided to combine closely related terms into a single color, using unit_descriptions_from_files.csv. One complication with having six datasets was that some geologic categories were described differently in each dataset, like Basin Material, Rugged vs. Each dataset had unique labels (and sometimes different data formats) so I spent a lot of time piecing the data together to create a cohesive map. Gathering and processing data Combining Geologic datasetsĪlthough I already made a geologic map of Mars and open-sourced the code, this moon map was much more difficult because the geologic data was split into six different datasets.
