PROJ 9.8.0 was released on March 2nd 🥳
More info on https://proj.org/en/9.8/news.html

As a significant change in EPSG, ETRS89 datum ensemble now has 57 members. Most of them are realizations from European countries.

https://spatialreference.org/ and
https://crs-explorer.proj.org/ are already up to date.

News — PROJ 9.8.0 documentation

*PROJ in the browser*

Finally, after a long time and learning a lot in the process, I am getting a webpage that uses PROJ to perform coordinate transformations (similar to cs2cs)

https://jjimenezshaw.github.io/wasm-proj/transform.html

Best features:
- fast!
- it uses grid files when needed, downloading only the needed part of them.

There's another one that replicates projinfo:
https://jjimenezshaw.github.io/wasm-proj/projinfo.html

It has its js library behind it. I'm still developing it, improving it & adding more features.

Enjoy!

CRS Transformation Tool

Four years ago, the Ukrainian border guard Roman Hrybov stationed on Snake Island sent a legendary radio communication to the russian cruiser Moskva.

Preparing releases for #PROJ on my Macbook seem to be causing endless problems for me. Anyone wanna sponsor a laptop that runs Linux?
I'm considering submitting an abstract for #FOSS4GE2026 this summer. I know a thing or two about geodesy and the related infrastructure that makes geospatial data work. What would be interesting to FOSS4G attendees to learn about in that space? Anything you find particularly difficult or confusing? Let me know!
This issue will be extremely difficult to fix. Good chance it remains open for some time: https://github.com/OSGeo/gdal/issues/13961
Your work is awesome and I appreciate it! · Issue #13961 · OSGeo/gdal

What is the bug? I am sorry for stealing some of your valuable time, but I just wanted to take this opportunity to say "thank you" for the wonderful software that you make. I use GDAL (and QGIS, bu...

Dear Americans... if the British can arrest the King's brother, you can arrest Donald Fucking Trump and Bill Fucking Gates

You can pick *at most two* of these three things related to coordinate reference systems:

- I don't want to understand [work with] dynamic datums (time dependent coordinates).
- I want a single geographic CRS worldwide.
- I want centimeter accuracy.

Enjoy your choice!

PS In case you forgot from high-school, tectonic plates are moving. Each one on its own way.

Reflect Orbital wants to destroy the night sky to deliver "sunlight as a service". SpaceX wants to destroy Low Earth Orbit to launch one million "AI datacentres"

The only way to formally protest these two ideas is to file a comment with the US FCC, which is horribly complicated, but the American Astronomical Society has detailed instructions posted here: https://aas.org/posts/advocacy/2026/02/how-submit-comments-satellite-applications-fcc

Comments due March 6 for SpaceX and March 9 for Reflect Orbital. Write! Write! Write!

I'm really digging the FPV drone footage at the Olympics!
