Pascagoula, Mississippi, on foot, built from real map data
Every street and building here comes from OpenStreetMap: about 22,000 real building footprints and 4,000 real road segments with their actual names, including the US-90 high-rise bridge, Ingalls, the refinery and the beach. Building heights, roofs, colors, trees and parked cars are filled in automatically, so a house will be in the right spot with the right shape but not its real paint or roof. The shorelines and marsh are estimated.
