Next week I will be answering questions on Reddit in r/Maps. Come on by! www.reddit.com/r/Maps/comme...

Today I’m excited to finally start a project I’ve been wanting to launch for a long time: Color for #Geoscience. 🎨🌍 ℹ️ to build an open, community‑driven collection of palettes 📄 Contribution: github.com/dominicroye/... 🌐 APP dominicroye.github.io/color-for-ge... #ScientificVisualization #dataviz

#30DayMapChallenge | Day 14 OSM | This map challenges the idea that streets belong to cars, even so-called sharrows that still feel unsafe. Using an inverted speed-limit hierarchy, fast roads fade. Bold bike infrastructure reveals how broken and fragmented the biking network is.

Absolutely fascinating essay: “Are you seeing a robot's soulless prose? Or are you seeing the image of our Standard Eight English teacher, Mrs. Amollo”

#30DayMapChallenge | Day 27 Boundaries | A virtually rendered #LEGO map of the #BritishIsles, with each area in its own color and elevation shown by stacked plates. I also added an inset map for the first time, following the terrain style from my well-received #Arizona map.

#30DayMapChallenge: 21st century cartographers A wonderful challenge that allows us to dive into the work of some of today’s most creative cartographers and illustrators. www.cartographerstale.com/p/30daymapch...

#30DayMapChallenge Day 30: Makeover I remade my map from day 21 (bakeries in Paris) and tried to make it a bit more interesting by comparing population and bakery density.

#30DayMapChallenge Day 29: Raster Made a joyplot of Switzerland following @aasmith.bsky.social's instructions. I'm sure it can be improved but I really like how it looks already! For anyone interested: antonioantoine.com/2025/11/23/c...

#30DayMapChallenge Day 28: Black For today I suggest a challenge within the challenge: can you find which country each map is centered on?

#30DayMapChallenge Day 27: Boundaries How is the Arctic defined? Here are a few possible answers.

#30DayMapChallenge Day 26: Transport Stargazing and biking? Here are the parts of the EuroVelo network that have the least light pollution.

#30DayMapChallenge Day 25: Hexagons Somehow struggled to find interesting bee-related data, but here's the # of observations of the Western Honey Bee in Germany, according to @inaturalist.bsky.social data.

#30DayMapChallenge Day 24: Places and their names I wanted to try something... but it needs a bit more work :-)

#30DayMapChallenge Day 22/23, Natural Earth & Process Uploaded a tutorial of how I made my typhoon map using data from Natural Earth and Copernicus, check it out: m.youtube.com/watch?v=efiG...

Day 23 - Process Create a Joy Plot Map in QGIS I created a workflow for creating a Joy Plot Map in QGIS. I plan on adding more workflows or tutorials in the future. antonioantoine.com/2025/11/23/c... #30DayMapChallenge

Day 22 of #30DayMapChallenge ~ Natural Earth. The Bathymetry of Lake Victoria. #rstats #dataviz #gis #map #spatial

#30DayMapChallenge Day 23: Process I used QGIS to create one image per year, and then turned them into an animation using ffmpeg. The command used here to turn all the .png of the folder into one video: ffmpeg -pattern_type glob -framerate 2 -i "*.png" -c:v libx264 -pix_fmt yuv420p output.mp4

#30DayMapChallenge Day 22: Data challenge: Natural Earth

#30daymapchallenge | Day 22 Data: Natural Earth | The Great Islands Earlier this summer I finished this print version of my map from last year depicting our Great Lakes as islands. Been trying to learn more about lighting techniques in Blender—I think this was a big leap forward from 2024 version!

#30DayMapChallenge Day 21: Symbols

#30DayMapChallenge Day 20: Water Average (surface) temperature of the Baltic Sea from 1993-2023. Data from @copernicusmarine.bsky.social

#30DayMapChallenge Day 19: Projections Not very inspired on this one, so a map of the world's roads (natural earth data).

#30DayMapsChallenge Day 18: Out of this world Water on Mars?!

#30DayMapsChallenge Day 17: A new tool Played around with #rayshader to look at Mont Rainier (Washington).

#30DayMapsChallenge Day 16: Cell Mapped the most frequent natural-feature words in French commune names.

#30DayMapChallenge Day 15: Fire

#30DayMapChallenge Day 14: Data challenge: OpenStreetMap Let's have a look at trees in Vienna!

#30DayMapChallenge Day 13: 10 minute map (This might have taken slightly longer, I blame it on QGIS).

#30DayMapChallenge Day 12: Map from 2125 What if all of Greenland's ice melted? For today I played around with Greenland’s terrain elevation data beneath the ice sheet. Note: This visualization doesn’t account for post-glacial rebound or sea-level rise. Data from nsidc.org/data/idbmg4/...

#30DayMapChallenge Day 11: Minimal map Population in Iceland: coast vs interior.

#30DayMapChallenge Day 10: Air An attempt at visualizing pollen distribution in Europe, based on EUPollMap doi.org/10.5281/zeno... Made using QGIS and Python.

#30DayMapChallenge Day 9: Analog A quick map of Nuuksio National Park, near Helsinki.

#30DayMapChallenge Day 8: Urban For today I went for a simple map of the cycling infrastructure in Tallinn, Riga and Vilnius. Data from @ecf.com

#30DayMapChallenge Day 7: Accessibility Today's map answers the question: How far can you get in Brussels, in an hour? Starting point: Manneken Pis! Data from TravelTime API and OpenStreetMap.

#30DayMapChallenge Day 6: Dimensions Here is a 3D map of Bjørnøya (Bear Island), part of the Svalbard Archipelago (Norway). I added relief to the map with Blender (using ArcticDEM). Original map from the Norwegian Polar Institute.

#30DayMapChallenge Day 5: Earth Here's a map of the tree canopy in Idaho!

#30DayMapChallenge Day 3: Polygons Visualizing territorial claims in Antarctica.

#30DayMapChallenge Day 2! Flight Connections in the Nordic Countries. The capitals clearly emerge as hubs, as well as other cities in more remote areas (e.g. Tromsø). Greenland was not included as part of Denmark. The data is from Alasdair Rae's Map Academy (2023). Year unknown.

Getting started with #30DayMapChallenge! Tried to represent population density in Finland based on 5x5km data from Tilastokeskus/Statistics Finland.
