How do gta v story locations differ from gta online maps?

Grand Theft Auto Online shares the same fictional state of San Andreas and city of Los Santos as GTA V's story mode, allowing players to explore the identical open-world environment. However, GTA Online evolved post-launch with major updates adding entirely new locations such as the Diamond Casino & Resort complex, surrounding areas, and expanded rural zones. These additions were designed to support multiplayer-specific activities like heists, businesses, and competitive modes not present in the single-player campaign. While the foundational map remains consistent between both versions, Online's dynamic content updates have created distinct gameplay spaces and objectives that extend beyond the original story's narrative structure.
