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.

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!

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

"Russian warship, go fuck yourself" 

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!
