DGL’s map gallery for #30DayMapChallenge 2023

November came and went, and with it the fifth annual map challenge. The concept is simple: every day has a theme, which is interpreted more or less freely and refined into beautiful cartographic visualizations.

The Digital Geography Lab partook this year with a whopping 29 contributions by 10 lab members. These maps are a globetrotting travel through five continents and cover a range of themes, datasets, and methods from population and dogs to – gummy bear cartography?? Mapmaking was spearheaded by our PhD student Matti Hästbacka, who posted the maps X and Mastodon and created half of them!

See our map gallery for this year is below. Also check out our maps for the year 2022.
