S-Map replicates Seoul's full 605 km² footprint as a 3D digital twin, built from drone-captured spatial data collected since 2018 and deployed citywide from April 2021 with roughly 600,000 buildings and six layered underground-utility models. Its Open Lab service lets agencies and companies run urban simulations, from sunlight and wind studies to autonomous-vehicle and delivery-robot testing.

The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →Sources

Four digital twins: who may open them — and what are they for?
The same label covers a sealed national security asset, a browser tab anyone can open, a bookable simulation lab and a live operations dashboard. Access is the axis that separates them — and it decides what each twin can honestly claim to do.

|---|---|---|---|---|---|---|---|
| Virtual Singapore: National 3D City Model and Digital TwinSingapore, 🇸🇬 | 2014 | Completed | Scaled back | Official | National government, Private company | About S$73 million (~US$53 million), as reported by Reuters; the former NRF programme page is offline. | Sealed: rolled out to agencies behind 'internet separation'; the promised public access never launched. |
| Tokyo Digital TwinTokyo, 🇯🇵 | 2021 | Live | Ongoing | Official | City government | not public | Open to anyone: a free browser viewer, with ward point clouds released as open data in December 2024. |
| S-Map — Seoul 3D Digital Twin PlatformSeoul, 🇰🇷 | 2021 | Live | Ongoing | Official | City government | not public | The lab in between: agencies and companies run simulations on roughly 600,000 buildings through its Open Lab. |
| One Network Unified Management (city operations digital twin)Shanghai, 🇨🇳 | 2019 | Live | Ongoing | Peer-reviewed | City government | not public | The operations pole: a live twin coordinating transport and emergency response rather than planning studies. |
