Eleanor Lutz’ veröffentlicht einen Atlas of Space, eine Sammlung von zehn Karten und Datenvisualisierungen rund um Planeten, Sonnensystem und Space.
Die nun dritte Karte des Projekts ist eine wunderschöne geographische Karte des Mars, inklusive ausführlichem Python-Tutorial über Sammlung und Verarbeitung der NASA-Daten auf Github. Prints der Illu gibt’s auf Redbubble.

This week’s map is an artistic rendition of the geologic map of Mars designed by the USGS. I used the same geology data as the original map, but I added more topographic and label data, redesigned the visual style, and also edited the key for a more general audience.
One of the most difficult parts of making this map was translating the key into plain English. The original USGS map was designed for geologists, so I had to look up almost all of the vocabulary. For example, my abbreviated definition for a caldera rim was “The rim of an empty magma chamber left behind after a volcanic eruption.” The original description was “Ovoid scarp, outlines single or multiple coalesced partial to fully enclosed depression(s); volcanic collapse, related to effusive and possibly explosive eruptions.”
The individual layers used to make this map. 1-3: Geologic units, geologic contacts, and geologic features from the USGS dataset. 4-5: Hillshade and slope from a different USGS elevation dataset. 6: Nomenclature from NASA IAU. 7-8: Gridlines and a custom 3D effect designed in Photoshop.
I also spent a long time trying out different map projections for this design. I wanted to accurately show how much of the planet was made up of each geologic formation, so in the end I decided to use an Eckert IV equal-area projection. This type of map distorts object outlines, but it preserves the relative area of shapes across the globe. Eckert IV is not great for visualizing the polar regions, so I also added four inset maps to the corners to show each hemisphere of Mars (North, South, East, and West).
