Everything You Wanted to Know About Vector Tiles (But Were Afraid to Ask) 🗾✨

https://www.openstreetmap.org/user/daniel-j-h/diary/404061

I collected my thoughts on vector maps and vector tiles after having spent some time reading the mvt spec for the first time 🦧💡

Happy year of #OpenStreetMap vector maps! 🎉

Ever needed to simplify street networks? I did. And it is a pain. So we joined forces with @anavybor and @JamesGaboardi and wrote an algorithm that does that for us. And can do for you, as it is available as a Python package called `neatnet`.

Here's a short blog about it - https://martinfleischmann.net/simplification-of-street-networks/

And here's, not so short preprint - https://arxiv.org/abs/2504.16198

But you probably want the package. That is here - https://uscuni.org/neatnet.

Happy coding!

The Clearance project will be funded by the NGI0 Commons Fund @NGIZero from the NLnet foundation @nlnet . It aims to improve data quality by acting as a proxy between #OpenStreetMap and data consumers, holding back suspicious changes while continuing to replicate all other valid changes.

Great map by @jurgentje at https://jurgen.gaeremyn.be/map.html showing that municipalities in Benelux rely on Microsoft or Google for email much more than in France or Germany

More info in Jurgen's blogpost https://jurgen.gaeremyn.be/2025/03/08/european-critical-dependencies and his interview on the situation in Brussels https://www.bruzz.be/actua/column/data-analist-brussel-te-sterk-afhankelijk-van-microsoft-en-google-2025-03-19

There will be on-premise MS Outlook behind some - many? most? - of the blue and green, so dependency on Microsoft will be higher than these colors suggest

Pour la #journeemondialedeleau j'experimente le relief avec #blender et c'est juste fou, avec l'ajout de courbes de niveau ombrées avec le module snap, je trouve ca fou (oui je me jette des hibiscus). Merci @geotribu pour les géniaux tutos comme dhab. Ca faisait longtemps que je voulais tester, c'est fait! (non sans jus de cerveau quand même pour le traitement des raster pour avoir un beau MNT). La carte est en cc by sa as usual.

Mes tous premiers patchs pour @josmeditor ont été mergés ! 🥳 🎉

Le premier permet d'afficher l'incertitude de la position sur une trace nmea. C'est vraiment utile avec des traces #RTK

Et au passage, les cercles peuvent aussi afficher l'age de la correction. C'est fort pratique pour visualiser des pertes de connexion.

I also confessed I sometimes get bored of LLMs (this got a bunch of people nodding) — bored because they are so logocentric and middle-of-the-road, a society-scale regression to the mean. This quote from prof Lumumba-Kasongo captures it well:

"[creativity] is so much about
trying out weird things — and AI
is so much about averaging.
It's the people invested in playing
in that space of the anomaly and
playing with the unexpected who will continue to thrive"

Elasticsearch and Kibana go back to open source, as in "OSI approved license" 🎉 Shay Banon (Elasticsearch's initial author and CTO of Elastic) gives more details with a bit of history. Seeing the old logos brings back warm memories from when I discovered this super cool search server while I was using Lucene. https://www.elastic.co/fr/blog/elasticsearch-is-open-source-again
