Could you build this?
Partial The web front-end relies on Three.js, but processing and serving massive metropolitan 3D geographic data (OpenStreetMap building heights, terrain elevation tiles, real-time transit APIs) requires custom geospatial ETL and rendering optimization.
What it would actually take: The architecture requires processing OpenStreetMap building footprints and national elevation DEM data into optimized 3D glTF/3D-tiles, served over a CDN. The frontend uses Three.js or Mapbox GL/deck.gl with custom shaders for atmospheric lighting and procedural building extrusion. The hardest part is performance optimization to stream, batch, and render hundreds of thousands of urban geometries smoothly on client browsers across varied hardware.
