The High Definition area of Downtown Chicago was extracted from the Racing Sim game Race Driver GRID 2, developed by Codemasters. Source map was edited from a mod Race Map Pack by Derkuwinator: https://dekurwinator-mods.bitrix24.site/
It was then further remastered to see use in free roam gameplay styles that Grand Theft Auto is well known for.
Google Maps 3D scanned area is added as complementary to the existing as to certify map is not an island and rather an illusive landlocked zone. GTA 3 (III) was the only 3D GTA to feature such a way of depicting a world to players of the franchise.
