After last year's success, we have opened a registration to 2025 instalment of **Spatial Data Science in Python** as a standalone course open to anyone.

It is perfect for anyone looking to dive spatial data analysis using Python, regardless of prior experience.

If you mean the recent paper in TGIS on intersection miscount, then our preprint contains a comparison to that one - arxiv.org/abs/2504.16198.

Adaptive continuity-preserving simplification of street networks

Street network data is widely used to study human-based activities and urban structure. Often, these data are geared towards transportation applications, which require highly granular, directed graphs...

Ever needed to simplify street networks? I did. And it is a pain. So we 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 - martinfleischmann.net/simplificati... and package - uscuni.org/neatnet

Original network on the left, simplified one on the right.

Just arrived in Bristol for #GISRUK! Will be doing a workshop on urban morphology tomorrow morning and then a talk on street network simplification on Thursday. Anyone around?

Finally a new #Shapely feature release! 🎉
Shapely 2.1.0 highlights include initial support for geometries with M or ZM values, functionality for coverage validation and simplification, and much more.

For a full overview, see shapely.readthedocs.io/en/latest/re...

#python #geopython #geospatial

Code snippet showing the initial support for M values, illustrating that with a POINT M.

i dont like plugging my own shit (and I haven't pushed the complete edition yet)--but anything you can do with the monopoly mapmaker you can do much better with Python

If you haven’t sone so yet, go and listen this interview with @geoffboeing.com by @rsfrankl.bsky.social, @levijohnwolf.bsky.social and @darribas.bsky.social. Esp. the last section on open source in academia is something that should be a part of every syllabus. podcasts.apple.com/cz/podcast/t...

On this, we crunched the numbers on what the Green Belt is made up of, based on our own (urban) form and function classification (urbangrammarai.xyz/story/). Results (+ code) over at:

urbangrammarai.xyz/green_belts_...

The gist is there are different "shades of green", some of them not very green.

Polars API will feel more “native” to you. But pandas is everywhere. Hard call.

This is a really nice visualisation of Local Moran's I used to capture local spatial autocorrelation. It very clearly unpacks how we calculate the I and what makes a value significant. observablehq.com/@siliconjazz... Great job! #gischat #dataviz #geospatial

Guessing from the example in your blogpost, there is no reason why it should not work. GeoDataFrame.explore just builds the folium.Map for you behind the scenes. We don't do anything else there.

Assuming the question about recording, I think it exists but am yet unsure about if it os going to be released. If I get my hands on it I’ll make sure to share it as well.

Time to share slides! I delivered an invited talk at an International Seminar on Urban Morpho-Science, showing some early results of an ongoing, yet unpublished, work we do on scalable urban morphometrics capturing structure od cities. “From a building to a region” - uscuni.org/talks/slides....
