World map?

[Iscah]

That's what I was thinking of, yes, though trying to assemble it properly to scale and not 'split apart'.

Some starting points I was thinking of:

• Ul'dah will fit neatly into the curve of Central Thanalan with the two gates lined up, then scale Western Thanalan to connect with paths into Ul'dah and Central
• Gridania's inn and airship landing are visible across the lake in Central Shroud so those maps can be lined up. (Although oddly the lake isn't drawn with the same shape on both maps.)
• Several of the La Noscea maps show an outline of the coast and the location of Limsa
• Should be able to trace rivers across multiple maps?
• Depending on how accurate the teleport fee distances are (ie. whether they're based on a true scaled map or not) it would be possible to get the exact size/placement of regions with two aetheryte locations.

It's not quite as simple as sticking each map next to the entrance/exit to the next area, because some seem to have distance between them. Sometimes you can see the same area from both sides of an area break line, sometimes you can see a path that you 'warp' to the other end of (eg. Limsa's bridges to field areas), sometimes you can't see where you've come from.
