Day 4 of #30DayMapChallenge: Clusters

🏰 France protects over 6,000 châteaux, fortresses and palaces as historic monuments. Each hexagon covers ~30 km. The darker the color, the more castles it holds. The highest concentrations are highlighted with outlines.

#30DayMapChallenge pick of the day - @Adam Roberts took every building in Paris and lined them up by use, largest first, at the same scale - and you can remake this with his interactive web app for any district in the city!

Every river in Africa, every day for a year. The monsoon lifts the Niger and the Blue Nile, then swings south to the Zambezi, while the Congo never stops. Data: GloFAS (Copernicus, ECMWF)

A tree can be right outside your window and still be missing from the map.

Day 1 of #30DayMapChallenge: the trees of Cluj-Napoca leaf out at the pace people added them to OpenStreetMap. 5,881 so far; 2,250 were added in 2022 alone.

Inspired by 2019 animation of New York's trees, raining down in the order they were added to the data.

Is there a tree near you still missing from OpenStreetMap?

Day 1 of #30DayMapChallenge: Points. I mapped the tsunami stones of northeast Japan.

“Do not build homes below this point.” That line is carved on a stone in Aneyoshi, set there after the 1933 tsunami. In 2011 the sea came up the valley and stopped short of it.

#30daymapchallenge Day 1 Points | Fall Foliage: Street Trees

Madison hit a milestone of 100,000 street trees in May of last year, and the city began planting about 1,000 more this fall.

This is still a draft. I am not finished with it in terms of style nor substance. Trying to work on some different visual language, color themes, and typography. Curious what followers would want to see added or revised for this to be useful as a reference map for #geopolitics.

Day 1 of #30DayMapChallenge: Points
To start us off for this year's challenge, a Scrabble points themed map of NZ. How many points is your town worth?

Two terrible days of rain in Istanbul, and it wasn't the same city everywhere.

Beykoz station got 274 mm, almost 4× a normal October. Florya: 62 mm.

I mapped all 36 stations as hexagons. Geçmiş olsun!💙

While I am not a QGIS user, I know many of you in my network are - so here comes a new plugin by @Nika - 𝐐𝐆𝐈𝐒𝟐𝐖𝐞𝐛𝐌𝐚𝐩. This tool turns a finished QGIS project into a single interactive HTML file you can simply share w anyone.

The recipient just double-clicks it to s, open popups and even explore 3D terrain and extruded buildings - no QGIS, no login, no web server. Your styling travels with it too. Thanks to @Lawrence Xiao for bringing this to my attention!

A masterpiece of precision and artistry: Guillaume Henri Dufour’s Topographische Karte der Schweiz (1833–1863). Created at an impressive 1:100,000 scale, this 25-sheet national map set a new standard for scientific cartography in the 19th century. Steel-engraved with t uses delicate hachures to sculpt the Alps in three dimensions—capturing Switzerland’s dramatic terrain with remarkable clarity. Centered on the Bern Observatory and produced during a period of rapid technological progress, the map supported military planning, infrastructure, and national unity.

I built "Avalanche Map" as a desktop app with @glazeapp to plan ski touring adventures! The Glaze agent just figured out how to pull the latest avalanche report from the official Swedish avalanche website - including detailed topo shading and slope angles. It supports 3d maps ut by the aspects affected by today's danger.

Building niche software like this with just a few prompts is great

#MakingMapsPretty
I’m developing a #QGIS tool to generalize and smooth a DEM, then generate a shaded relief and matching contour lines, all adapted to the selected level of generalization. Azimuth, height, Z-factor, and contour interval are controlled with a single click.
