Those of you that follow my social media pages during the month of November will of course be familiar with the 30 Day Map Challenge – a social media cartography challenge predominantly centered around Twitter. For each day of the month, there is a different theme or topic to map.
There are no requirements on how many maps are made – some people may just do a couple, while others might attempt to cover nearly all of the themes. Ever since doing my previous self-styled 7 Day Cartography Challenge back in 2017, I’ve enjoyed the concept of just sitting down and smashing an interesting map out. It’s a great way to avoid resting on one thing for too long, exposes me to new datasets and skills, and the results are pretty awesome too!

For this year’s 30 Day Map Challenge, I decided to see how far I could get, and here they all are! I hope you enjoy them – just expand the section to see the larger preview.
