Made some improvements this week to my map of United States real property (federal land, buildings and other fixed structures) - new agencies and better geocoding, including USPS, TVA and State - filter by property type (e.g. "parking structure") and year built - where available, actual land areas

TASA(Taiwan Space Agency) has recently released five images captured by FORMOSAT-8. According to TASA, the image resolution met the originally designed 1m resolution. This is a great improvement over FORMOSAT-5’s 2m resolution images. www.tasa.org.tw/zh-TW/announ...

cool new map built on pmtiles + @protomaps.com

I recently nerd-sniped myself into thinking about political points of view on maps, and wondering whether it’d be possible to create OpenStreetMap-derived, Wikipedia-informed national borders on a Protomaps base map legal for educational use in countries in conflict. medium.com/@michalmigur...

short note about S2 Geometry bdon.org/2025/12/19/s...

"We will not devalue the EPSG dataset by including such inappropriate geodesy and cartography."

Was looking at my cloudflare worker serving maps via pmtiles, saw there is a new dashboard on cloudflare with a map of request locations, poked around into how it works and indeed cloudflare themselves are serving their map via the pmtiles cloudflare worker

For those who couldn't catch our latest podcast live, here's the recording! Thank you @bdon.org for sharing your thoughts about all things cloud-native maps, and to everyone who tuned in live, especially those joining us from Norway and Egypt in the wee hours! youtu.be/VACq-POg_dw

happy html day ❇️

The business model of food is drinks The business model of transit is real estate The business model of maps is ?

blogging update: i am posting through my dissertation, it is very bare bones and a painfully niche topic but I'm pretending this is me making progress: placing.technology

just opened up limited edition preorders for poetry.camera ~ (it feels weird to do self-promo on bsky but i also want to celebrate our first batch drop!! a long time coming)

The Visual Display of Qualitative Information

I sometimes muse about the savage job-destroying nature of the open source community: hundreds of thousands of developers working tirelessly to unemploy as many of their peers as possible by giving away the code they've written for free.

Make cool stuff. Share it with people

tired of landing pages and single-page sites. you should make websites with as many pages possible

My site now has a search feature! You can also filter by region or theme to narrow results. Technical details: this is a Pagefind implementation, completely static, using the astro-pagefind integration. Overriding parts of the default UI with Tailwind feels like a bit of a kludge but hey, it works.

I don't want gen AI in my geospatial technology. I want

Enjoyed being on @jeremyjung.com's Software Sessions podcast! Topics: * Maps as a primitive of the web * The appeal of static sites * @protomaps.com vs. OSM * Dynamics + biz of FOSS vs. SaaS * Thinking about "finishing" projects Listen + read transcript at www.softwaresessions.com/episodes/pro...

I talked to @bdon.org about self hosting static maps with @protomaps.com! He mentioned open source maintainers usually only hear complaints from their users 😣 If someone's project helped you build something let them know! www.softwaresessions.com/episodes/pro...

cooking some test tilesets for new Rasterio PMTiles plugin pmtiles.io?url=https%3A...

This week, I'm working on creating dynamic Open Graph images for various parts of allmaps.org. The first is for latest.allmaps.org, a small website that shows the last 250 maps georeferenced with Allmaps.

I've been very quiet on Bluesky. It's time to change that! Hello, my name is Bert, I'll post about maps and computers.

New example program for generating the minimum viable PMTiles, a single PNG: github.com/protomaps/go...

Updated 80s.nyc to support HTTPS finally thanks for the tip @chrisamico.bsky.social !

It continues to bother me that it’s possible for me to read newspapers from 100+ years ago and not data journalism from the 10 years ago (when I wrote about this back then, the main cause was technical breakage and not corporate malevolence)

#NICAR25! If you make interactive data visualizations and want to learn more about making them accessible to screen readers, I wrote this article showing how to make basic interactives accessible: joemurph.com/article/deta...
