Map people, I need your help! What projection might have been used to create this map? Note how the meridian have a distinct bend in them at around 80 degrees north.

Here's a new version with tweaked projection parameters and an attempt at mitigating the vast difference in size between smallest and largest country. Is it clear to you what's going on?
This is as close I get to recreating the map. Azimuthal Equidistant projection centered on 55°N, 5°W.
For the perfect map of the Danish Realm I think the projection center needs fine tuning, but this is a good starting point.

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)

Best features:
- fast!
- it uses grid files when needed, downloading only the needed part of them.
There's another one that replicates projinfo:

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

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!
