made a quick interactive map of building heights in toronto (2025 data)
big fan of tippecanoe->pmtiles->maplibre->github pages workflow, can pretty easily take a ~300mb .shp like this and render it all in-browser (no fancy db, server, or saas hosting)

Today #Wikipedia turns 25 years. Let's appreciate this monumental project of open knowledge and international collaboration!
Without open knowledge, data and transparency we cannot see uncomfortable facts and where humanity need to act.
I wanted to see if there are any countries at all with a median age below 25. Turns out, there aren't just a few.

@quixoticgeek Had to look it up for myself, and bingo, Dominic Roussel has photographed the street signs on the pin.
Personally I'd have put This Street above That Street for a more authentic linguistic treatment, but that's just being picky about this.
@blag @quixoticgeek What really stands out to me about this phenomenon is that the world is chock full of streets named after men. Very few are named after women. But rather than take that opportunity, they'd rather just have it be generic.
Lokjo is a european substitute for googlemaps.
No cookies, no data, no nothing.
When you search locations by category (clothing shop, coffee bar, museum etc) it shows all locations at once. Except for corporations and chains, they get a grey dot.

Yet another reason to tut at the Mercator map projection
https://brilliantmaps.com/mercator-vs-true-size/
Fascinating, thanks!
Here's obligatory link to great bit from TV's "The West Wing." Where cartographers compare Mercator versus Peters projections for stunned C.J. and Josh.
The head map guy is played with perfect drollery by the invaluable John Billingsley (Star Trek: Enterprise; The Man from Earth, etc.).
Cartographer: "Nothing's where you think it is."
C.J: "Where is it?"
Cartographer: "I'm glad you asked…"
How #Google #Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it:

Scotland's National Library is having a free map festival next month, if you're interested in #cartography and anywhere near Edinburgh on 6th Feb.
La philosophie de CoMaps en matière de respect de la vie privée, qui est notamment le domaine dans lequel elle s'éloigne du projet dont elle est issue : Organic Maps.

Time for a new topic. We will look at Viking 2 later.
Pop quiz - which was the first solar system object after Earth and the Moon to be mapped? You at the back? - sorry, it's not Mars. No, the first after Earth and the Moon was Venus, by Francesco Bianchini, working in Rome. He made a globe of Venus in 1727 and published maps in a book in 1728. Of course the features are illusions, probably contrast effects in the eye.
