Is the gta online map the same as the gta v map?

Grand Theft Auto Online is described as the online component of Grand Theft Auto V, and both games are set in the same fictional state of San Andreas, which is based on Southern California. The open‑world design of GTA Online lets players roam San Andreas, including the countryside and the city of Los Santos, just as in the single‑player campaign. Because the online mode uses the same world, the map that players explore in GTA Online is identical to the map used in GTA V.
