Something going on with #geopandas on #Windows today that broke @movingpandas unit tests? https://github.com/movingpandas/movingpandas/actions/runs/14266650165/job/39992053542
Struggling with slow GIS processing? Tony Albanese's article demonstrates a lightning-fast method for generating transects using #Geopandas and #Polars, reducing processing time from days to seconds.
Thank you to #Kone & Mai and Tor Nessling Foundations for supporting this work. A quantitative work like this would not be possible without a robust suite of FOSS tools. My thanks to the maintainers of #QGIS, #pandas, #geopandas, #duckdb, #dask, #statsmodels, #jupyter and many more!
Seeking recommendations for a #WebMapping tutorial / course?
Slightly at sea on where to start.
- My current JS skill level is _extreme novice_.
- I don't have access to ArcGIS.
- Comfortable with #QGIS [*] and the #python #geospatial ecosystem (#geopandas #xarray #rasterio and plotting with #matplotlib)
Suggestions welcome. TIA. 
* I have looked at the qgis2web plugin, but having some issues associated with my aged laptop (2012 mbp running Ubuntu) and a 'Wayland session'.
Geocomputation with Python copies have arrived 
Somehow, things feel much more real if you can touch them.
Fun fact: the cover was designed in #QGIS. Speaking of going full circle ...

"R⁵py is a #Python library for rapid realistic routing on multimodal transport networks (walk, bike, public transport, and car). It provides a simple and friendly interface to R⁵, the Rapid Realistic Routing on Real-world and Reimagined networks, a routing engine developed by Conveyal. #r5py is inspired by r5r, a wrapper for R, and it is designed to interact with #GeoPandas #GeoDataFrames."
