I want to display a map like Pokémon GO.

I can't find a way to customize those designs, leaving information on roads and buildings.
If anyone knows, please let me know.

I'm thinking of creating a map of my own design using the Android app.

Pokémon GO maps reflect real-life buildings and roads, but the design is original, so I'm thinking of changing the design and making a map, but I can't think of any way. So I'm thinking of collecting all the building address information and drawing them in real time with openGL.
