From Topi Tjukanov, the #30DayMapChallenge is a "daily mapping/cartography/data visualization challenge aimed at the spatial community. The idea is to create (and publish) maps based on different themes on each day of the month using the hashtag #30DayMapChallenge."
Check out 30daymapchallenge.com for more.
This page shows my maps for 2022 and 2023.
For more, here are my maps from the 2021 #30DayMapChallenge (external StoryMap) and the 2020 #30DayMapChallenge (external StoryMap). I also presented at the North American Cartographic Information Society's (NACIS) 2021 conference, where I discuss my experiences during this challenge. Watch my presentation "The GISt of It: Discoveries from a Daily Social Mapping Challenge".
