The image was shared by a Reddit user on the popular platform along with a note that the map was data mined by himself/herself based on the recent leak of the Project Rene Playtest build.
The Reddit leak highlights the fact that the playable areas in the playtest have been marked in red. Comparing the game screenshots portrayed in the map and the map by itself has only confirmed the accurate lineup of the map.
According to the above post, the map indicates that Paris has been chosen as the location setting. The tipster justifies this statement by saying that he/she found references to the actual IRL photos in the game files.
