It started as a detailed model of the Old Town and grew outward on national LiDAR flown in 2018. Anyone can open it in a browser, and it stays deliberately separate from Estonia's national platform.

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.

Tallinn runs its own 3D city model (the "linnamudel"), a LiDAR- and BIM-based digital replica the city uses for planning, architectural review, daylight-and-shadow, noise, air-pollution and solar-potential analysis, with a public online viewer at gis.tallinn.ee/linnamudel. It began as a detailed Old Town model and has grown toward a citywide model built on Estonian Land Board LiDAR (spring 2018) and building data. Since 2020 the FinEst Centre for Smart Cities at TalTech has helped extend it into a fuller "digital twin" — the EU-funded GreenTwins pilot (2020–2023, jointly with Helsinki) added a dynamic green/vegetation layer and a physical city-planning hub. It is the city's own model, distinct from Estonia's national 3D and e-construction platform.
