Output with roman numerals in cs2cs for lat-lon

[jjimenezshaw]

After this post
https://mapstodon.space/@jjimenezshaw/113017850151676527
we could have this "Easter egg". It is totally fine if it is not added.

It is only intended to work in output (not parsing input) for lat-lon.

I have not documented it in docs/source/cs2cs.rst. If you consider it should be in the documentation, let me know.

• Tests added
• Added clear title that can be used to generate release notes
• Fully documented, including updating docs/source/*.rst for new API

While this is fun I am -1 on this. It's just extra clutter in the code without any real benefit.

I'm +1 to this. How else is someone going to be able to translate ancient roman coordinates? 😛

I would be -1 on roman coordinate locale support however 😉

Uhmmm, I do not now if it is a flaw, or a feature. It was implemented in a way that 0 uses no-symbol. It would be strange something like d9'12"M , o even d'"S d'"OC for null island. But at the same time I like it even more, because it shows how roman numerals work (or not work).

Unless the Roman Empire is going to step up and commit to funding the ongoing maintenance of this feature, I'd be wary of adding support for this proprietary notation that lacks an official publicly available specification. Also, in my experience, the Empire is really bad about returning e-mails or responding to questions. I'm not even sure if they are fully staffed anymore.

What have the Romans ever done for us?

What have the Romans ever done for us?

Apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, the freshwater system, and public health… what have the Romans ever done for us?

I'm -1 on this too (sorry!). It's awkwardly jimmying an obsolete counting system (no zero, no negative numbers, no fractions) into a modern application. I fear it would also invite other silly PRs.

While I'm on the subject, does PROJ support centesimal degrees? This was (still is?) used for surveying in some parts of Europe.
