#30DayMapChallenge 2025 day 1: points

Inspired by my stay in Maastricht performing Carl Orff's #CarminaBurana with Brabant Koor & the Jussen Brothers.

Today’s map shows Dutch place names ending in -tricht, -drecht, -trecht—derived from Latin Trajectum, meaning river crossing. #toponyms

Maastricht = Mosa Trajectum.

Made with #QGIS #OpenStreetMap and #vectortiles from @maptiler.bsky.social

Still tickets for the amazing concerts weekend: https://jussenmaastricht.nl/

Heute (virtuell im #qgis) Kleines Wiesental - völlig unbekanntes Pflaster

Linux and Windows packages of #QGIS release 3.40.12 "Bratislava" (LTR) and 3.44.4 "Solothurn" (upcoming LTR) ready on https://qgis.org. Make maps not war!

Looking for a raster-first tool/workflow (ideally in #QGIS/ #GRASS) to site textile recycling containers as a coverage problem:
• 100×100 m population raster
• Candidate sites: cells with pop ≥200
• Coverage range: 400 m (Euclidean)
• Target: 80% population covered (min # of sites or max coverage)

Trigger Happy: Live edits in #QGIS

Wie viel #Grundsteuer bezahlt man für Wohngrundstücke in Stuttgart oder Tübingen - und wie viel auf dem Dorf?

Einige Monate und einige Millionen HTTP-Requests später haben wir am Wochenende in der Stuttgarter Zeitung eine Analyse veröffentlicht, die diese Frage für jede Gemeinde in Baden-Württemberg beantwortet.

Tools: #QGIS (ALKIS-Daten), #Rstats (Scraping und Analyse).

Today I did some small changes to a #qgis plugin by changing three or maybe four lines of code, but that improved usability a lot, already. And I see further small improvements that look a bit obscure now, but may become doable if I understand enough Qt/PySide to edit the source code where needed.

I'm looking for an offline #geocoding solution to process millions of sensitive customer addresses. All within a small part of Germany and it needs to run on a normal laptop. Any ideas? #qgis #gis #gischat #osm #openstreetmap #opensource

I'm looking for better ways to convert between #QGIS VectorLayers and #GeoPandas GeoDataFrames. #pyogrio and #arrow look promising (reduces run time by 50%) but when I try to wrap it in a Processing script, it gets tricky ...

Local elections in New Mexico - early voting has been running for 3 weeks.

This analysis of early voting looks at the turnout rate of Dem voters, compared to the total number of registered Dem voters in each precinct in Alamogordo.

There is some surprising info here, some of it encouraging, some of it concerning.

The map is shaded to represent Dem turnout. Lighter = lower turnout percentage, darker = higher turnout percentage.

What surprises me is that the precincts with the highest Dem turnout rate are five times larger than for the lowest rate. That's a huge spread of motivation/action. (I was expecting a spread of two to one or a little bit more.)

After three weeks of early voting, with one week early voting remaining, and election day remaining...some precincts already have Dem turnout of over 40%?! Some neighborhoods are fired up! They live in the redder (newer, wealthier) precincts in the outskirts of Alamogordo.

Somehow, we gotta tap into their enthusiasm and redirect a bunch of it to the older, less wealthy parts of Alamogordo.

Example: Mesa Verde (precinct 15) is a red precinct, but already 1/3 of those Democratic voters have cast ballots. That's pretty good.

Contrast that with Chihuahuita and Walker. Their turnout is struggling to achieve 1/10th of their total number of registered Dem's.

How is early voter turnout in your city? Are you helping any local candidates?

We need to boost civic engagement...for the rest of our lives, and involve lots more younger folks.
