Trying to set up a full map, not a mini-map

Everywhere I look, all I can find are tutorials for mini-maps.
I’m trying to set up a system where the player is able to open a full map with their location on it, and possibly an option for a “local map” when in cities.

Big note: I’m streaming maps to make a large world

The only thing I could find from someone is from the market place, but I was hoping to avoid using it if possible.
Any help would be appreciated greatly. Thanks!
