How to: GDAL with Martian Data

I’ve seen a lot of tutorial on working with GDAL with Earth data, but not a lot for planetary data, Mars included. As I use GDAL a lot (and in need of reminder myself), why not write a how-to with Martian data.

MOLA, but in different projections (https://core2.gsfc.nasa.gov/PGDA/images/MarsTopography_GMM3.jpeg, https://astrogeology.usgs.gov/search/map/Mars/GlobalSurveyor/MOLA/Mars_MGS_MOLA_ClrShade_merge_global_463m)

Martian Maps, Maps, Maps

(This is a part of Martian Series I’m queueing in this moment)

So, compared to Earth, which is mapped often already, and the Moon, which has been fully mapped using NASA”s Lunar Reconnaisance Orbiter, Mars hasn’t been mapped as often. The highest resolution global topographic map of Mars until now is produced using MOLA data (Mars Orbiter Laser Altimeter), which, although pretty precise in altitude, only has the resolution of about 463 m/ pixel. But! Based on MOLA data alone, there are a lot of interesting Mars maps in different style being produced. Basically this post was born because of me stumbled upon this vintage-style Mars map created by Eleanor Lutz a.k.a. Tabletop Whale. I knew that there are a lot of interesting (data-wise and style-wise) maps on Mars, so I will share a few I can think of.
