When there was a sudden empty slot in our #sotmeu25 schedule, Topi Tjukanov stepped forward and talked about the #30DayMapChallenge that happens each November.

Day 13/100: The year I became MapTheClouds 🌍

2021 = transformative. #30DayMapChallenge + #30DayChartChallenge

Same year: launched https://maptheclouds.com, created brand/logo, refined COVID-19 network viz for Romania.

Lesson: discipline beats waiting for perfect conditions. Some days → proud work. Others → functional experiments. Both mattered. Showing up builds creative muscle memory.

End 2021: not just projects, but practice + platform + direction.

#30daymapchallenge overdue final map: Cartogram of every current mandate for Germany's federal parliament by party and type of mandate. I have wanted to look at a figure like this for decades and finally decided to be the change. @a_watch @dawum
My "non-serious cartography" that I created for #30DayMapChallenge helps in understanding the decolonization of Crimean place names

The idea that Russian and soviet renaming on the territory of Ukraine are harmful and should be abolished is obvious...

For those who just joined: I make maps (200+ about Ukraine), work with QGIS & Python, teach architecture, and do 3D printing. OSM contributor since 2010, #30DayMapChallenge participant since 2019.
Here you'll see: work in progress, failed experiments, Ukrainian cartography, and GIS nerding.

While I love the #30DayMapChallenge, I couldn't fit it in my schedule last year. I like the idea of making for-fun-maps based on fixed themes. So I created a list of 52 subjects for myself to use over the course of this year to create maps that I can share. You can find it on https://52maps.org, or you can follow @52maps. If you want you can join me and share your for-fun-maps using #52maps.
For what it's worth, I've updated my shed https://anisotropi4.github.io/shed/30daymapchallenge.html with links to the data used and published a register of data and associated licenses used in talks and visualisations https://anisotropi4.github.io/shed/opendata.html
