Two Earth Maps?

[Arrowstorm]

I realized there's two different Earth maps. I believe one is part of Vanilla, and the other the Scrambled Continents pack. Is there a difference?

EDIT: Never mind, the difference is apparently that the Scrambled Continents map has a predefined shape.

Both maps have a predefined shape; the vanilla one has set interiors for the continents while the Scrambled one has randomized interiors (but you knew that already).
