Today is rest day, in all dimensions.

So why not computing the administrative areas around the world I've visited while running and cycling with @duckdb #SQL and a bit of #Java

https://github.com/michael-simons/biking3/blob/main/bin/collect_administrative_areas.java#L210

Doing all the #spatial stuff directly from within the db, working on temp tables.

Eventually getting a deeply nested #JSON structure out of it:

https://github.com/michael-simons/biking3/blob/25fd2c462954395f84ca3ec5fd4f81851746caa0/schema/api.sql#L632-L673

Thanks @lukaseder for inspiration, @hannes for that piece of tech :)

Things I learned the hard way: administrative boundaries are mess in software engineering. Similar to names (of people), and dates. Like literally all reasonable assumptions will be wrong.

"Encode #spatial data as #topology in #Python!

With #topojson it is possible to reduce the size of your spatial data. Mostly by orders of magnitude."

https://mattijn.github.io/topojson/

We're proposing a new section "Machine Learning of Spatial Data" for the #rstats CRAN Task View: Analysis of Spatial Data.

https://github.com/cran-task-views/Spatial/pull/89

Feedback is welcome -- are we missing key packages or ideas?

Feel free to reply or DM.

Un chercheur français du CNRS refoulé des Etats-Unis pour avoir exprimé "une opinion personnelle sur la politique menée par Trump". Ce chercheur dans le domaine spatial a subi un contrôle aléatoire à son arrivée à l'aéroport, au cours duquel son ordinateur et son téléphone personnel ont été fouillés. Le FBI a ouvert une enquête contre lui, depuis abandonnée. Les Etats-Unis ne sont plus une démocratie https://www.lemonde.fr/international/article/2025/03/19/etats-unis-un-chercheur-francais-refoule-pour-avoir-exprime-une-opinion-personnelle-sur-la-politique-menee-par-l-administration-trump_6583618_3210.html

I've added a new experimental branch to the #rstats rnaturalearth package to test reading data directly from the #GDAL virtual file system, supporting both raster and vector data.

This enhancement allows reading the data without needing to download and unzip it into a temporary folder.

You can try it here:

https://github.com/ropensci/rnaturalearth/tree/feat/use-virtual-gdal

Feel free to give it a try, and let me know how it works for you!
