Alright, let me elaborate what I mean on the title since I can't think of any "word" to describe this, not good on english that much.

So, I wanna have like another seperate "map" of the gta san andreas. Like there's gonna be 2 of them. One is for events, one is for the game itself. One have mapping, one have different one.


And if I would like to add interiors? Where should I exactly make it? High above the sky or down below? Or there's a better place to make a interior. Thanks, I hope you get what I mean.

Sorry for grammar errors and english skills.

Virtual world is what you need,you can search them up in ******.
And,I'm not that experienced in mapping but sky above is better.

As Verc said, virtual worlds are perfectly for what you need!
For your mapping, you can do below the ground to avoid weather's disturbance. If you want to do a mapping in a specially virtual world, you will need to use streamer plugin.
