Assembled from the map
Every street, river, park and tagged tower comes from OpenStreetMap. The rest of each city is generated to match how it is really built, and the landmarks are modelled by hand.
Real data
Streets, coastline, rivers, parks, rail lines and building footprints with their heights, all from OpenStreetMap.
Generated city
Blocks fill with the local way of building: brownstones, south-facing towers, dense Tokyo houses, Main Street storefronts.
Hand-built landmarks
Twisted towers, lattice spires, castles and bridges, each placed on its real footprint and lit for the night.
