#30DayMapChallenge was started in 2019 on Twitter by Topi Tjukanov. This daily mapmaking challenge takes place each November, bringing together people passionate about mapping science and art. Maps can be found on Twitter and other platforms using the #30DayMapChallenge hashtag. While the DGL is preparing for the new season in 2023, we suggest checking out the maps that the lab members made almost a year ago.
