How do I define the points in the 'polygons.txt' file?
You dont.

Also there are no negative coordinates, the map is treated as if no wrap around existed, except for below.

The wrap around map edges will share a vertical map line, one to the left one to right.
You then need to stitch the wrap around TT/SZ manually together with connections in the xml like so;
<connection t1="Chihuahua-Durango" t2="Mexico City"/>
<connection t1="Acapulco-Chiapas" t2="Sinaloa-Guadalajara"/>
<connection t1="064 Sea Zone" t2="011 Sea Zone"/>
<connection t1="064 Sea Zone" t2="028 Sea Zone"/>

In map.properties this must be true
map.scrollWrapX=true

That should work.

@GREGOREK If you want territories that wraparound, you could treat them like archipelagos like Kyushu and Honshu on almost any map.

I am interested in automatic generation software you have.

The year is 1911. With the Boxer Rebellion and the rise of the Eight-Nation Alliance being a recent memory, China once again comes into focus. The new nationalist revolution will bring the Great Powers even closer to each other than at the turn of the century, far too close for comfort. This power struggle leaves the Empire of Japan with two options: one, as in our history, is to support the burgeoning revolutionaries against their and Japan’s great rival, the Qing Dynasty. But why must they pretend to support ROC for any reason other than their ability to further destabilize China as a political entity? When will there be a better opportunity for Japan to exert their will throughout Asia? And so emerges a second path forward: the Second Sino-Japanese War. The Nationalists and Imperialists are quick to form a united front to repel the invasion, though tensions remain high and the state weak.

Seeing this as a desperate attempt for complete control of critical Chinese markets, the United States declares war on Japan in short order. This brings about a state of war between the US and the Anglo-Japanese Alliance. With the Royal Navy occupied in both the Atlantic and the Pacific, Germany makes a similar conclusion to Japan: they will never be given a better chance to rout the British surface fleet and hastily advance into Warsaw and Paris. Austria-Hungary follows suit, and the currently warring empires of Italy and Turkey quickly pick sides. And as the united Chinese front quickly collapses and the European theater draws to a stalemate, all eyes are on the United States; will the combined might of her main naval rivals collapse in on her, or will her swift conquest of Canada fund an expeditionary force capable of ravaging Africa, the Pacific, or Europe?

Welcome to War Plan Red-Orange, a new alternate history TripleA map that explores the scenario posed by the United States’ War Plan Red-Orange, hypothesizing a war with both Japan and Great Britain. If you love maps like Domination 1914: No Man’s Land, but wished they were more global in scope, this is the map for you. Of course, it’s built from the ground up on the original Domination, so it’s more of a cousin to NML with its own identity than a sister. This means that when we get around to it, there will be a unique tech system and a unique implementation of the Balkan Wars, the Arabian jihad, and the communist uprisings in Russia.

If you would like to help beta test this project, there's a Discord group I'm making that you can join if you can PM me your username. If you don't have a Discord account or would rather stay here, we will also run some test games through this site if there's demand for it. Before I send out a download link, I'll wait to gather any immediate feedback people have on the map, then I'll make those changes and send that version out. To help with that feedback:

Entente: Japan, Britain, France, Italy, Russia
Centrals: China, United States, Germany, Austria, Ottomans
Turn order: Japan->China->US->Britain->Germany->France->Austria->Italy->Ottomans->Russia
