![]() 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. Map design in Illustrator and Photoshop. ![]() There is no perfect software that fits everyone's needs, so you'll want to understand the pros and cons for the different raster and vector programs before choosing. I use Adobe Photoshop and Illustrator, but you can also use the free open-source programs Gimp and Inkscape. You'll need software for editing raster and vector images ( this article explains the difference). The instructions in this document under the "Conda" section are probably the most relevant if you've installed Python as described above. For the code in this repository you will also need to install GDAL. After you've installed Python using these tutorials, you can use Git Desktop and the instructions in this tutorial to download the code and data in this tutorial. Software Carpentry has great tutorials for installing Python (scroll down and follow the directions in the Bash Shell and Python sections), getting starting with Jupyter Notebooks, and beginner-friendly Python programming. Special instructions for beginners If you're new to coding: Dependencies can be installed with pip install -r requirements.txt. Python dependencies: pandas cartopy matplotlib os numpy shapefile jupyter. ![]() If you have comments or suggestions for this tutorial, please let me know on my blog! You can also buy the finished map here if you like. Software used includes Python 3.7.1, GDAL 2.4.1, bash, Illustrator CC 2019 and Photoshop CC 2019. Elizabeth first got interested in space after watching the movie Apollo 13 in 1996, and still wants to be an astronaut someday.This repository explains how to make a geologic map of the moon using open-source data from the USGS, IAU, and NASA. Elizabeth is also a post-secondary instructor in communications and science since 2015. in Space Studies from the University of North Dakota, a Bachelor of Journalism from Canada's Carleton University and a Bachelor of History from Canada's Athabasca University. Her latest book, "Why Am I Taller?", is co-written with astronaut Dave Williams. Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, working inside a spacesuit, and participating in a simulated Mars mission. She was contributing writer for (opens in new tab) for 10 years before joining full-time, freelancing since 2012. Elizabeth Howell (she/her), Ph.D., is a staff writer in the spaceflight channel since 2022 covering diversity, education and gaming as well.
