#30DayMapChallenge takes place for the third time already in November. It was initiated by Topi Tjukanov in 2019 in Twitter and the idea is to create (and publish) maps based on different themes on each day of the month using the hashtag #30DayMapChallenge.
From Estonia, Positium, Estonian Land Board and Evelyn Uuemaa published all the 30 maps in this year’s challenge. All in all, there were more than 1200 mappers in 2021 and more than 9000 maps were created for the challenge.
In previous years, several staff members of the Department of Geography have participated in the challenge but this year also many master’s students from our MSc programmes (Geography, Geoinformatics for Urbanised Society and GEM) joined the challenge. Below you can find a selection of maps by our students and staff members.

Natural Earth: what time is at the poles? Time zones are converging at the poles and time has no traditional meaning at poles. McMurdo Station in the South Pole follows New Zealand time because it’s mainly serviced from NZ. North pole does not have any stations and therefore usually polar expeditions may choose to observe the same time zone as their country of origin or may opt to use UTM.
