There is only one hand crafted map; Navezgane. Pregen01, Pregen02, and Pregen03 are named as such and are all just pregenerated random worlds.

Literally any other map by any other name is a randomly generated world with a name randomly generated from a list.

That includes both Western Territories and San Junipero- What you're seeing in those maps is the new A20/A21 random generation in action.
