#30DayMapChallenge Day 30: Makeover

30 Days - 30 Maps!
A huge thank you to everyone who took part: your maps and ideas were truly inspiring.
And a big shout-out to those who completed all 30 maps: much respect!

To wrap it up, here's a makeover of day 26: I'm revisiting German settlement names. My final post for this year's 30DayMapChallenge presents the geographical distribution of selected suffixes, all in one image, with multiple maps.

#30DayMapChallenge Day 26: Transport

My map takes a look at air transport today and shows the current connections of the once largest airline in the world.

#30DayMapChallenge Day 25: Hexagons

The blue tit can be found throughout Europe, in adjacent regions of Asia, and in North Africa.
The map shows bird counts for the year 2025 using a 25 km hexagon grid.

#30DayMapChallenge Day 24: Places and their names

I downloaded 84,513 German settlements (cities, towns, villages, hamlets) from OpenStreetMap and analyzed their suffixes. The classification was based on an article from Wikipedia.

#30DayMapChallenge Day 18: Out Of This World

I used several Python libraries, including skyfield, to recreate the current constellation of stars above me in the night sky.

#30DayMapChallenge Day 16: Cell

I created a 50×50 m grid for the urban area of Kiel. For each cell, I calculated how much of it is covered by buildings according to OpenStreetMap.

#30DayMapChallenge Day 05: Earth

Geothermal energy can serve as a renewable source for heating buildings and generating electricity.
Today's map shows the temperatures at a depth of 1000m in Europe.
