Job density in the Twin Cities — how the geography of employment shapes the metro. Ty to QGIS wiz @cchurchili.bsky.social for help with the height extrusions.

Everytime Blender auto-resets a preset I had painstakingly created I lose a part of my soul

"the medium of data visualization is the decision" (of how to map from variable to visual) @jerthorp.bsky.social

Kicking off #NACIS2025 with @cchurchili.bsky.social & “Advanced Terrain Modeling with Blender”. If you’re unfamiliar his work, it’s amazing: churchillgeo.com

*Sigh*. My intended python demo for NACIS is gonna get tripped up by a version of Python released last Tuesday (3.14), which is not currently compatible with numpy. (I would prefer not having to spend time explaining how to downgrade a fresh Python install.) 😢

the issue with bluesky is that it took me 2 months to find this amazing trick by @southarrowmaps.co.nz and it has seemingly no engagement

This animation shows the difference between rotating the orthographic camera (first half) which produces foreshortening, and adjusting the Y-value of the input normal to the displacement node (second half).

Definitely bit off a lot on this latest upcoming blog post...

The mapping soundtrack atm

I have a weird GDAL problem. I am trying to assign a spatial reference system to a JPEG world map and then reproject. Everything works if I use gdal_translate to make a GeoTIFF, but if I create a VRT as an intermediate step the corners of the reprojected image are filled. What gives?

The accent on an 'i' will be the death of me

im just so jazzed about blender + satellite mosaics

To one and all a happy anniversary of the beginning of the world in the Maya long count calendar (give or take a day or 2).

shoutout to whoever did USGS art in the 90s

you can do anything in blender yk

A reminder that air pollution is a trans continental problem. After a +7000km, air quality in the Caribbean area and Southern USA is being impacted by a long distance event. While models are useful for such predictions, they need to be verified (and corrected if needed) w/satellite observations.

Museums in London spend more time talking about the war of the Spanish succession than the American revolution smfh

Averaging GOES images together

I wrote a post on my #blog about the variety and history of #hachure, the distinctive strokes on 'old' #maps. Big thanks to Daniel Huffman (of course), Jake Steinberg and Alexander Fries for help with feedback. churchillgeo.com/variety-in-h...

My deepest, nerdiest take is that the real secret to explaining cartographic techniques are the printing and surveying techniques avaliable at the time.

I think my biggest cartography pet peeve is moving from rainbow palettes to overly detailed coastlines. If you feel seen, check out mapshaper.org for fast, easy, and good detail reduction:

🧪🛰️🔥🧊 Smoke over the pole? Maybe, first its detection is difficult but it can be done. Regular visible image do not show it unless it is super thick (where a regular white cloud would look brown or even black). In this case, regular visible image does not show any indication of it. But ... 1/n

Never going to catch me slipping

Right now I post most on LinkedIn mostly because its where my feed is most full of cool techy stuff and projects. Only thought there

People make fun of the US for being full of scams, paywalls and poor data but fwiw I have *never* had as many problems accessing map data as I have anytime I am working on a project in the UK

Today is my last day at the Washington Post. Something exciting coming next! If you love when data, graphics and journalism all mush together, sign up to get notified when ~~something exciting~~ launches this summer. www.ashendruk.com/soon.html

These charts by Gabrielle Merite are gorgeous. 📊 I love the mix of images and 3D effects combined with the application of proper dataviz principles, The typography is especially good and has a cheeky story behind it. figuresandfigures.substack.com/p/behind-the...
