Road positions, names, building footprints, parks, rail and river geometry come from OpenStreetMap. Mapped trees, crossings, bus stops and paved areas add street detail. Lane counts, one-way directions and bus lanes use mapped tags where available. Missing widths use approximations; paint styling and sprites are authored. City Chambers and Central Station have bespoke roof treatments. Traffic signals follow mapped OSM signals where present; this snapshot has none, so they are authored at junctions of named through streets, with give-way elsewhere. Street lamps combine mapped OSM lamps with authored lamps along main roads. Pedestrians use the mapped crossings. Rail viaducts and Central's train shed are drawn above the streets that pass beneath them; trains are ambient and authored, not a timetable. Landmark markers are curated approximate locations.

This is a contemporary map with a fictional 1990s visual treatment — not a historical reconstruction. The map covers a selected part of Glasgow. Traffic, pedestrian incidents, police pursuits and ambulance response are simulated. Story characters and safe-house entrances are fictional. Safe houses use a wardrobe and garage menu; walkable interiors are not implemented.
