choropleths are a gateway drug to spatial analysis bsky.app/profile/knaa...

now just time for a LISA bsky.app/profile/andr... (it's usually the off-diagonals that are most interesting :) knaaptime.com/urban_analys...)

"Much of modern life would not be possible without the scientific innovation that NSF investments supported. "There is no guarantee the US will continue to lead in scientific innovation, and without innovation, talent and resources will naturally flow elsewhere" www.theregister.com/2025/02/21/n...

All open source is political. Even Rouault – archetypal GIS "random person maintaining the code that supports all modern digital infrastucture" – commited to GDAL github.com/OSGeo/gdal/p... - will now print "Trans rights are human rights" with `--version`. #gischat 🏳️‍⚧️👏🏼🏅

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...

i mean the tariffs make clear there's no macroeconomist anywhere near this administration, but this is like dead simple regional IO modeling. someone call IMPLAN.

in pysal world we call this a legendgram bsky.app/profile/andr... github.com/pysal/legend...

My favorite combo materializes: social ecology + spatial econometrics. I’m headed up the coast this fall to join the faculty of urban planning and public policy at UC Irvine

Congestion pricing is basically universally accepted as among the most efficient and normatively positive public policies in all of urban planning and transportation economics

a housing shortage is different from a land shortage. we dont have a shortage of land; we have a policy of unwillingness to build up. this crazy thing called *density* happens when the market substitutes capital for land, and it's literally how cities are supposed to work bsky.app/profile/wash...

PD&R also provides/manages all HUD's spatial data hudgis-hud.opendata.arcgis.com (which was my job in 2013). Archive what you can now, but if there's current data on e.g. *where* subsidized households are living, then supporting HUD's fair housing mission is impossible. bsky.app/profile/soci...

Counterpoint: But I hate that fucker

semi annual reminder that the winter 2025 release of PySAL is out github.com/pysal/pysal/... lots of bugfixes, enhancements, and new features across the ecosystem

Another great resource: the Segregation Tracking Project. We built off NCES data to create Longitudinal Imputed School Database. Race/eth and free lunch data for every school in the US 1991-2022. We impute erroneous/missing data but retain original CCD values. edopportunity.org/segregation/

John Roberts and other fox news granpas have themselves to thank for Trump toadies flirting with ignoring court orders www.theatlantic.com/politics/arc...

Yeah so the Constitution isn’t really in effect right now

Graff, who wrote this, is a former editor of POLITICO.

somehow the epa's environmental justice data seems to have gone under the radar www.epa.gov/ejscreen. They duplicate a lot of census data in there too

the FTP site and API are also down! bsky.app/profile/cbgo... if you need ACS or pre-2020 census data (tract or blockgroup) I've got the whole country mirrored for the 'census data profile' (read: pretty much everything you'd ever need) in parquet format at open.quiltdata.com/b/spatial-ucr

zed is lovely. Though atm the builtin REPL still doesnt fully grok environment variables that come along with conda/pixi environments. Depending on how launched from CLI, kernelspec sees the right packages but breaks on proj/gdal metadata paths that should come for the ride (and do, e.g. in vscode)

One of my favorite feeds is ‘Quiet Posters’, a feed of posts from people you follow who don’t post very often. A nice way to make sure I don’t miss things 🤗 bsky.app/profile/did:...

whoa. quiet rollout for a pretty big update: docker for win/mac can access usb now blog.golioth.io/usb-docker-w... finally got my dormant skyconnect hooked up to @home-assistant.dev (in docker) on my mac studio

any chance the @posit.co people know how to make this work without (a) an iframe, and (b) resorting to tectonic? (i recognize debugging pixi path stuff is probably out of scope...) bsky.app/profile/knaa...

here's a self-documenting template repository for doing open science & reproducible research (spatial, in this case--i.e., how i do all my work). Put this together for our grad students but maybe useful here (pixi + quarto + codespace) docs: knaaptime.com/rypyrx repo: github.com/knaaptime/ry...

Special kinda party when sdsu gets the distinguished professor franklin @rsfrankl.bsky.social to deliver the annual Getis lecture in spatial analysis
