Open City · Day 8/30 · Utopia 🌳
Every surface car park in Cluj-Napoca as a park, in a Three.js 3D map: 86 ha, 20% more than its mapped parks today. A scenario, not a plan.
Inspired by @KennyPirman.
Which car park would you turn into a park first?

Open City · Day 6/30 · Vintage 🗺️
Cluj in 1955, drawn again from its own map. The paper burns open on today. A window on today's map shows 1955: tree rows, a few houses, a field; today, blocks. Inspired by @vcraciunescu.
What was there before your neighbourhood?

Open City · Day 5/30 · Senses: Sight ☀️
From Cetățuia you see a fifth of Cluj (~35 km², estimated), and the day is 13 minutes shorter than on a flat horizon: the same hills hide the sun.
How much of your city can you see from your hill?

Day 5, second story: from the Empire State's 86th floor, about a tenth of Manhattan is in view, and Central Park is nine-tenths hidden behind the towers.

Open City · Day 4/30 · Clusters 🧭
911 places in 77 ha: the center of Cluj-Napoca, Romania.
72% of residents reach 6 of 8 kinds of service in a 10-min walk (estimated). Deepest gap: Cordoș, a ~35 min walk to a doctor.

Open City · Day 3/30 · Polygons 🏙️
In 1975, the hills of Borhanci were not yet built.
Day 3 of #30DayMapChallenge: Cluj-Napoca grows hectare by hectare. The city built after 1975 climbed almost 40 m higher, and 1 in 3 people there lives over 300 m from a stop (1 in 7 in the old xander Bogachev.
Data: estimated (satellite model)

Open City · Day 2/30 · Lines 🚋
A line on a map is a route someone takes.
Day 2 of #30DayMapChallenge: tram 100 ridden across Cluj-Napoca, from Piața Gării, the railway station square, to Bulevardul Muncii. Then the whole network appears: 72 lines and 438 stops, drawn by tMap.
Inspired by @underdarkGIS (Anita Graser), who reads a line as a journey before a shape.
Data: mapped (OpenStreetMap) · relief estimated

Open City · Day 1/30 · Points 🌳
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?

#30DayMapChallenge starts tomorrow. 🎉
I can't wait to see the maps you'll make. I'm sure this year will bring an explosion of imagination. 🙂
Happy mapping! 🗺️

Every map I make stands on someone else's work. With a few secret ingredients of my own. 🗺️
This Sunday, #30DayMapChallenge begins, and my theme is a thank-you. Following FOSS4G Bucharest live in 2019 showed me how freely this community shares code, data and maps.
Thirty days, apoca in 3D, from open data only, each with the person who inspired it.
Whose work inspires yours?

February 9 → May 19, 2026.
100 consecutive days of showing up. Not 100 perfect maps, but 100 days of building in public: from GIS foundations to browser-native 3D, client delivery, and experimental spatial systems.
🔗 Interactive calendar (each tile opens its LinkedIn post): maptheclouds.com/100-day-map-ch…
What became clearest is what I want next: spatial tools that genuinely help people navigate real-world decisions, in Cluj and beyond. Maps as portals and instruments, not as an escape from the world outside the screen.
The arc is complete. I'm shifting focus back to architecture, delivery, and selective collaborations on enterprise spatial platforms, high-performance 3D visualisation, and interactive mapping systems where technical rigour and visual clarity both matter.
If that sounds close to your roadmap, let's talk.
