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. 🔗 martinfleischmann.net/sds/micro/

Call for papers! A special issue on Open Urban Data Science, by Filip Biljecki, @geoffboeing.com, Hugo Ledoux and me, is open. We are looking for open software tools on spatial data science, cities, and related. www.sciencedirect.com/special-issu.... If you have any questions, I’m happy to answer!

The opposite of conclave is convlex

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

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

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 knaaptime.com/urban_analysis bsky.app/profile/knaa...

reason 3485 you're doing your students a disservice by teaching esri products. Use open source. bsky.app/profile/mapc...

If you’d like to do the same in #python, here’s a little tool from the PySAL family allowing just that github.com/pysal/legend...

I really liked this idea of using a histogram as a legend in a choropleth map (since land isn't unemployed; people are), so I made a little guide to doing it with #rstats, {ggplot2}, and {patchwork} www.andrewheiss.com/blog/2025/02...

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...

The 2025 GISRUK abstract deadline has now been extended to January 31st, 2025! We're really excited to welcome papers rethinking the role "Process" plays in GIScience. We hope to see your abstract real soon! app.oxfordabstracts.com/stages/76668...

The GIS Research UK (GISRUK) 2025 Call for Abstracts is live! This year's theme is **Process in Geographic Information Science,** re-thinking the link between the patterns we see and what we represent on our computer screens. See you in Bristol April 23-25! gisruk.org/gisruk-2025

At long last... An official way to convert from office formats to #markdown with Microsoft's new {markitdown} #python package!!!! Next week's datathoning will be fun :) github.com/microsoft/ma...

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.

Lots of discussion on greenbelt today ahead of new #NPPF. - Greenbelt covers 12.6% of England, compared with just 1.3% used for housing (6.2% if you include gardens) - There's no greenbelt in the south west or East Anglia (beyond Cambridge). researchbriefings.files.parliament.uk/documents/SN...

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

I don't think I've shared with you the recording of the workshop on GeoPandas 1.0 we did with Joris Van den Bossche last year at GeoPython.

We're heading to #WUF12 to Cairo next week and organise and event on monitoring urban fabric ops Wednesday at 3pm. wuf.unhabitat.org/event/wuf12/... Everyone is invited! Also, if you are coming to Cairo and would like to catch up, please let me know! I'll be around until Thursday.

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....

Today was the first time I’ve used #Pixi to manage students' Python environments and I must say, compared to last year's Conda, it was a breeze. The only issue was caused by Avast Antivirus, which removes python.exe from the environment thinking it is a virus :). For, reasons, you know. #python

The teaching started today with a session aimed at Python environment installation (using Pixi) and general setup. Only to find out that wifi on campus is down 🙃. I’m all for improvisation but I’d be happier without this one 😂. What a start of the term.

We may have some leftover budget within my research team. I got some ideas how to spend it but, how would you spend it? Some cool gear to recommend? Other ideas?

Two weeks ago I did a keynote on 'The emergent structure of cities' followed by a workshop ‘A Brief Introduction to Spatial Data Science’ during the UrbanMetaMapping conference in Saarbrücken. Now live on YouTube! 🔬Keynote: www.youtube.com/watch?v=pG2j... 🎓Workshop: www.youtube.com/watch?v=MQKc...

Some time ago I've moved my activity primarily to Mastodon (and I love it!) but it feels that only part of my network has moved there. So, here I am for the other one! Expect stuff primarily about cities and open source for spatial data science. #intro
