What are the main differences between gta v story mode and gta online maps?

The verified evidence from Wikipedia discusses the development history of Grand Theft Auto V, including its release timeline across different platforms and the development team size of approximately 1,000 people. However, this source contains no information about map differences between Story Mode and GTA Online modes. The evidence focuses solely on development aspects like release dates, team collaboration, and marketing strategies, without addressing gameplay elements or map variations between the single-player story mode and multiplayer online components.
