Day 22 | #30DayMapChallenge — Data: Natural Earth

A vintage-style map using @NaturalEarth 1:10m physical layers, zoomed to the Eastern Hemisphere (60°E–180°E, 50°S–50°N).
Soft colours, clean lines, and a classic atlas feel. 🌍✨

Day 19 — Projections 🌍
Same world data, one transformation:

• Goode Homolosine → interrupted + distinctive

Projections change everything — even before you add any data.

Day 18 – Out of the World 🚀🔴
Mapped Mars today using the Viking global mosaic from NASA/USGS.
Rebuilt the extent in R and plotted the planet in a clean equirectangular view.
Amazing what you can do with a simple JPG + {terra}!
