My 30DayMapChallenge, 20
 My #30DayMapChallenge, 2020
This year, as well as 2019, I took part in the best cartographic challenge #30DayMapChallenge where participants from all over the world created beautiful maps on the theme of each day.
Unlike last year, other cartographers from Ukraine also took part in the marathon. The map from Andriy Yaremenko is very interesting and unusual, and maps from some cartographers. As there will be statistics, I will attach it to the publication.

You can see many interesting and incredible works under the hashtag #30DayMapChallenge on Twitter.
The official repository for #30DayMapChallenge, It is a daily mapping/cartography/data visualization challenge aimed at the spatial community.

I am incredibly grateful to the wonderful Topi Tjukanov from Helsinki, Suomi for organizing this wonderful and much-needed cartographic holiday. Of course, it is difficult to come up with and make a map every day, but it is definitely worth it!


Here are my 30 maps about Ukraine. Enjoy!

Day 12: Map not made with GIS software
Sometimes we find ourselves in a place that is unfamiliar and incomprehensible to us. We try to find signs that are familiar to us, but they only confuse us. This map is about the relationship between physical and psychological space :)
Where am I?
I once got lost in a plain old park and it was something like that. All guidelines were wrong ;) So this map is about confusion.
