#30DayMapChallenge Day 9: Analog - Medieval castles 🏰

Printed small maps of castles on with a portable printer on a thermal paper. I like this dithering effect from low-quality printing

Used momepy library to calculate Simpson's diversity index

#30DayMapChallenge Day 6: Dimensions - Chiatura 🚡

The city in Georgia with a system of cable cars. Tried to make a 3d map with smth that has full info about itself only in 3d

#30DayMapChallenge Day 4: My Data - Istanbul book places 🧿

A bit chaotic map of bookshops and libraries I've visited

#30DayMapChallenge Day 2: Lines - ICT networks 🖥️

The purpose of this map was to look at all the networks without basemap. It's interesting to note how the structure differs in different countries

[Roman @altabbt]

Found out that in Stockholm there is a live advent calendar in December! Mäster Olofsgårdens are making it since 2005. On each day people are performing smth from old city's windows

I don't like their map so created new version. My girlfriend also helped me with design issues

#30DayMapChallenge Day 30: The final map - Marine traffic 🚢

The first map shows vessels by speed, the second - by vessel type. Was excited to make final map with ships, I can spend a lot of time exploring their routes

#30DayMapChallenge Day 29. Overture - Saint Petersburg courtyard wells 🟥

Red color represents courtyard wells - courts that are totally surrounded by a building. In Saint Petersburg they are often very narrow and authentic - city's landmark

#30DayMapChallenge Day 28. The blue planet - Sri-Lanka rivers 🇱🇰

#30DayMapChallenge Day 27 Micromapping - Ant's routes 🐜

Diving deeper into micromapping, ant's pathes around anthill enters are a good example! The resulting heatmap shows popular places around holes in ground - map of ant's home

#30DayMapChallenge Day 26: Map projections - Magellan's circumnavigation 🌎

Found really cool tutorial, how to make projection that minimizes distortion for a particular route: https://t.co/vYkuc7LTRb

#30DayMapChallenge Day 25: Heat - Tropical cyclones 🌀

Huge winds running in tropics, bringing heat and destruction with them

[Roman @altabbt]

#30DayMapChallenge Day 24: Only circular shapes - Roundabouts count in the world 🔄

Kinda ugly viz, but still informative. Day is for circles - so I've plotted data on circle crossroad in the world. Top 1 is France - but with strange driving rules for roundabouts

#30DayMapChallenge Day 23: Memory - First childhood trip 🌅

I was small years old when first time travelled somewhere - parents took me to Anapa. Tried to recall as much places from that trip as I can and put them on a map. Other places are blured - so they are in my memory

[Roman @altabbt]

@_FishDentist Thank you! That map was made with osmnx (Python lib for OSM), geopandas and postprocessed in Figma

#30DayMapChallenge Day 22: 2 colours - Nicosia 🇨🇾

Wanted to show a place that has one name but separated. Nicosia is divided into two parts, like the whole Cyprus. It is the last capital in the world that is splitted

[Roman @altabbt]

@robertmaurerfan Thank you! It is Hex:FF8C00 for roads and Hex:FF6E17 for labels, with Emission surface in Blender

[Roman @altabbt]

#30DayMapChallenge Day 20: OpenStreetMap - German autobahn system 🛣️

Germany's cities are connected with high-speed Autobahns - you can drive with no speed limits at all

In my imagination from the top it looks like glowing network of cars spreading light all over the country

[Roman @altabbt]

#30DayMapChallenge Day 21: Conflict - Conflict risk index ⚔️

The level of conflict risk (the total index of many factors) over time. The higher the column, the worse the situation. Visualization tool - Aerialod, data from https://t.co/TFQ22y3hpH

#30DayMapChallenge Day 19: Typography - Hashima Island 🏣

I love Japanese kanji and for the typography day I wanted to create smth in a post stamp. Hashima Island - abandoned island in Japan - is a perfect spot for this purposes and also for romanticizing abandoned places
