a single map is a set of 2D tiles. The way the larger world works is that maps can have child maps so there's a tree where each child's top-left is relative to their parent's.

For z-layers, a whole map is on one z-coordinate, relative to the parent's z-coord.

Eg: A multifloor dungeon base-floor map could have one child for each floor and then you could move the dungeon in 3D and have all the relative children still line up.
