Central Vancouver as one illustration, about 4.4 km across: Stanley Park, the West End and downtown to Gastown, False Creek, Granville Island and Kitsilano. Drag to pan, scroll or pinch to zoom; every block is drawn.
Drawn from Google's Photorealistic 3D Tiles with one isometric camera, redrawn tile by tile by GPT Image 2.5 Sunburst, guided by a structure map from the 3D model. Method after tinyrj, Tiny London and Isometric NYC.
The traffic is simulated: cars drive the real streets, lanes and signals, but not real trips.
