#OpenStreetMap Logical History — From technical diffs to reconstructed semantic object history.

An approach to reconstruct OSM object history at a semantic and geospatial level, beyond the technical object history.

It should help to review the OpenStreetMap changes. It supports geometrical and semantical object spiting or concept moved from one objet to an other.

We (@teritorio) publish a #MapLibre GL plugin we have made and using for a while about Clustering as Layer, with the particularity to have unfolded small cluster to direct interaction (some kind of spiderify). We are open to feed back.

The new algorithm for directed cheapest routes "slices the graph into layers, moving outward from the source like Dijkstra’s. But rather than deal with the whole frontier at each step, it uses the Bellman-Ford algorithm to pinpoint influential nodes, moves forward from these nodes to find the shortest paths to others, and later comes back to other frontier nodes. It doesn’t always find the nodes within each layer in order of increasing distance, so the sorting barrier doesn’t apply. And if you chop up the graph in the right way, it runs slightly faster than the best version of Dijkstra’s algorithm. It’s considerably more intricate, relying on many pieces that need to fit together just right. But curiously, none of the pieces use fancy mathematics."

"Ils sont indispensables au bon fonctionnement de quasiment toutes les entreprises et administrations mondiales : les géants de la tech comme Microsoft semblent aujourd'hui incontournables. Raison de plus pour s'en passer. Ce défi un peu fou, c'est celui que s'est lancé le land allemand du Schleswig-Holstein."

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.
