I would like to embetter the standard map of the game. I thought I could use the common free GIS services (as an example ArcGIS online) to do it. But I do not have a clue of how to proceed.
I think it could be an interesting feature.
as an example a brighter map for the Latakia battle:

or a detailed map for a Cyprus invasion starting in Ayia Napa

After we might be interested in some exotic features like Topographic maps. As an example the US topo maps can provide some stuffs:
here is the Porthmouth/Norfolk zone.

and it is all known in geodetic coordinates
Or may be we could be interested in more basic features like... having the display of the country names all over the world

There is a lot of possibilities with this.
