[SOLVED] What is the map based on??

Question

Cartography

Hello everyone, please tell me what the map was created on:

Answer 1

Take a similar one and reverse the colors, it will be like yours.
At the same time, write "Bib and Revo" correctly.

Answer 2

It also seems to me that the vector editor is drawn. But why?

Answer 3

It was drawn manually, I would give 15 minutes.
Hint: in google maps api you can customize your own map styles, there is even a wizard
