How to implement a map for the game?

Question

Android

I do not know how to formulate the essence of the question, so I will describe it here. How can such a thing be implemented?

Here is a map of the world. At first I thought that this was done in some way through changing the type of map from Google. Then I saw another map unlike the earthly one. The question is, how can this be done?
Ps when you poke on an area on the map (highlighted by borders), this area is highlighted.
Zs if this is a regular game scene, then how to make it? I would be grateful for help.

Answer 1

It's programmed.
Separate scene.
The boundaries of the areas on the map are predefined.
