Launched a few years ago by geographer Topi Tjukanov, the #30DayMapChallenge has taken the geovisual world by storm. With participants from all over the globe, the Twitter event challenges people to try out new tools and to get creative with map-making. We set out to only do a few maps, but ended up, to our own surprise, completing all 30 days. Scroll below to see all our creations for 2021. Thank you to our team members Ivan, Merli, Egle, Erik, Kaisa and Gerttu for contributing to this year's challenge. 

The #30DayMapChallenge made its return in November 2020. The challenge, originally launched on Twitter in 2019 by Topi Tjukanov, brings together map enthusiasts from around the world to showcase their work and explore the plethora of options in map-making. In that first year, we went all out and submitted a map for every day. In 2020, however, we took a different approach and explored new map-making tools and techniques. Ivan Vasilyev, Data Specialist from our Methodology Team reflects on his experience with the challenge.
