30 Day Map Challenge

November’s 30DayMapChallenge is fast approaching - and the daily themes for this year’s event have just been released!

The #30DayMapChallenge is an annual, community-driven event that brings together mapmakers from all over the world. Started by Topi Tjukanov in 2019, it’s become a global celebration of cartography, creativity, and data visualization. Each day in November, participants create and share one map inspired by a daily theme - from “points” to “Makeover” (redesigning an old map).

The idea is simple: make one map per day, share it on social media using the hashtag #30DayMapChallenge, and explore what others have created. There’s no competition, no prizes - just a fun way to learn, experiment, and be part of a creative mapping community.

 

"Doing less than 30 is also fine."

You can use any data or tools to complete a challenge. Here are the tools I expect I'll be using the most this year:

Maplibre - an open-source library for creating interactive web maps
OpenFreeMap - free global map tiles powered by OpenStreetMap data
Maputnik - a user-friendly visual editor for designing custom map styles
geojson.io - an online tool for drawing, editing, and exporting GeoJSON files
Mapshaper - a browser-based app for simplifying and editing geospatial vector data
