The July 2024 release of PySAL metapackage is available on pypi and conda-forge x.com/knaaptime/stat…
the new PySAL is out today! This release introduces the new Graph class and includes a *ton* of new stuff all across the metapackage github.com/pysal/pysal/re…
daily commute flows with libpysal and lonboard knaaptime.com/longraph/ the Graph and the GPU go great together
This month marks the release of pysal/spreg 1.5.0, the spatial econometrics package of PySAL. This new version mainly addresses features that users have long requested. It brings several new features, performance enhancements and bug fixes. (1/9) github.com/pysal/spreg/
Phew! I wrote up some thoughts on this 👇over at darribas.org/anotes/article…
Congratulations to Professor Daniel Arribas-Bel (@darribas) on being awarded the Taylor & Francis Award for excellence in the practice and promotion of teaching in higher education.
PySAL's BDFL is elected a Fellow of the American Association for the Advancement of Science! Congratulations Serge! sdsu.edu/news/2024/04/g… Open source is good for science

Sergio Rey is recognized for work as a leading pioneer of the Python Spatial Analysis Library (PySAL), downloaded two million times.
so, an opinionated take: 'Urban Analysis and Spatial Science' will be available from CRC Press in early 2025 :) the digital version (still in draft) is at knaaptime.com/urban_analysis/ comments, criticism, and feedback welcome.

Urban Analysis & Spatial Science
This text provides an introduction to the technical and theoretical foundations of urban analysis, a field with a long history and surging growth across multiple disciplines. It covers intermediate...
the januay 2024 release of @pysal_devs is live github.com/pysal/pysal/re… Tons of new changes and additions (im teaching "Spatial Analysis and Econometrics with PySAL" at WRSA in feb & "Python for Spatial Data Science" at @CARTO in march if you're looking to get your feet wet :) )
We were very lucky to have @QunshanZhao visiting us today @AaltoUniversity to give us a workshop about spatial optimization methods using open source tool #spopt in @pysal_devs. 🤓🌍 Super inspiring and useful! Thanks! 🙏😊 @AaltoGeoinfo
We have been working on the development of the open-source spatial optimisation package (@pysal_devs spopt) in the past three years and here is an update: ubdc.ac.uk/news-media/202….
This is just as good a last-monday of Aug. to remind the X-verse (?) our book "Geographic Data Science with Python" is out and about, you can order it if you want and/or you can enjoy it free online! All your #python needs for #geospaial + #DataScience in one neat package 🐍🌍🤖
📜📜📜Book launch day!!!📜📜📜 Four years (and many more moons!) in the making, "Geographic Data Science with Python", by @sreyog, @levijohnwolf and yours truly is published worldwide. Read more in our post: geographicdata.science/bookupdate/202…
new paper with @sreyog in EPB today :) journals.sagepub.com/doi/10.1177/23… If you care about residential segregation, but you ignore the way travel networks are designed, you're probably missing an important part of the picture
I am very honoured to share that I am one of this year’s awardees of the Distinguished Service to Regional Studies Awards. The award is granted by the Regional Studies Association @regstud youtu.be/PUeAcus0KTY

If you're into cities or open spatial science and needed another reason to come to NARSC in San Diego, @pedrov_amaral, Luc, @sreyog and I are teaching spatial analysis and spatial econometrics with @pysal_devs 👐 narsc.org/newsite/wp-con…
if i were to take some michigan NLCD data, use it to seed a little cellular automata model with spatial-stochastic transition rules, and animate the results, I'd be sorely tempted to call it "A Computer Movie Simulating Urban Growth in the Detroit Region"...

I was featured on NumFOCUS' Google Summer of Code wrap-up post! Had a wonderful experience working with @pysal_devs -- highly recommend to anyone interested in spatial data science! numfocus.medium.com/numfocus-7th-t…

Somehow I'd missed this... but (easy) isochrones are coming to the PySAL's sphere of influence (through Geosnap for now) 👇🔥
ok, i put the local isochone builder into the dev version of geosnap. Here's a quick overview nbviewer.org/github/spatial…… once i get some documentation kinks worked out, i'll cut a release. If any adventurers wanna kick the tires, I welcome whatever feedback you've got
The process of #networksimplification is on its way!🐍👨🏽💻 I need to share some exciting early results (on roundabouts) to keep the motivation going! It's a Mammoth task 🦣 and this is only the beginning... so #staytunned @pysal_devs #GSoC2022
