#30DayMapChallenge Day 28 - Black Friday

Black Friday or Bird Friday?

We think that birdwatching is better than impulsive shopping - even in November.
Our map shows the 1512 observations in Finland that eBird users have posted over the past Black Fridays (2015-2024).

#30daymapchallenge 17: A new tool
Helsinki enjoyed a grand total of 12 minutes of sunshine in November (1.–13.11). No better time to remember that yes, the sun does still exists.

This map shows Helsinki's shadiest / sunniest places. New tool? #GRASSGIS solar modelling.

#30DayMapChallenge Day 1 - Points
