Now I see: Mindblowing! Thanks, Daniel, for sharing this - even with code. I’ll forward this to some channels.

Thanks for the nice blog post.

But Z curve is not forgotten :) see e.g. this discussion about GeoParquet partitioning

Regarding GeoParquet partitioning: I’m interested in evaluating the best spatial partitioning scheme for generating GeoParquet files in order to get the best performance when reading them within a bbox. => Which algorithm do you recommend? Z curve? My favourite is KD/KDB Tree. But there are also Quad Tree, Hilbert Curve, etc.

By the way, do you know this nice post?

Pour info : je suppose que tu connais WaterWayMap https://waterwaymap.org/#map=2/0/0 et « Routage avec des lignes à travers des polygones » https://blog.rustprooflabs.com/2022/10/pgrouting-lines-through-polygons .

I’ll also have a look at GeoParquet and GeoDesk when I find the time. They might contain additional ideas I overlooked.

Very good. I would definitely take a look at GeoParquet 1.1 https://geoparquet.org/ - and if necessary contribute to it.

I respect in-house developments like Oma, but the chances of a new format like GeoParquet catching on are much greater.

Take a look at the long list of GeoParquet (and Parquet) software. And see also, for example, these interesting discussions on the subject here: https://github.com/opengeospatial/geoparquet/discussions/251 .

Dear @kumakyoo. Interesting project. I haven’t yet understood all your requirements. But have you already looked at GeoParquet?

And regarding the time consuming styling: Soon the QGIS plugin “AIAMAS - AI-Assisted Map Styler” will also support line and area symbology. This plugin allows quick symbolization and automatically suggests fitting colors and symbols for newly loaded vector layers. Feedback welcome! https://plugins.qgis.org/plugins/AIAMAS/

Hey 2hu4u: You can share QGIS symbology using the QGIS Resource Sharing plugin https://qgis-contribution.github.io/QGIS-ResourceSharing/ .

I didn’t understand all your queries, but I often recommend the following output in combination with “NWR”:

...
//out body; >; out skel qt;
out center;   

I’d be very interested in this feature implemented as part of OSM.org website.

Seem’s that it’s Microcosms was renamed to communities https://github.com/openstreetmap/openstreetmap-website/pull/3717 .

But the project name really only is about the functionality in osm.org . So the project name will vanish one day when it is merged.

@OpenBrian : Can you give an estimate when the pull request will be ready to be merged?

Hi Mateusz: I’ll forward your comments to Timon, the maintainer of the OSM Wikidata Quality Checker, who is now working in my institute IFS at OST.
