Digital Twins with TerriaJS and Magda
summary
Proof-of-concept combines TerriaJS and Magda to make a regional digital twin for Western Sydney (expanding from Penrith to eight LGAs, ~10% of NSW population). The demo serves 130,000 buildings now and targets ~500,000 buildings for the next release, stitches LiDAR and photogrammetry down to ~2–2.5 cm, and shows real-time buses and IoT feeds for a “pulse.” Tech stack includes Cesium; Magda provides federated, authorized access (no central copy). Major issues: 3D/BIM formats, IP/contract barriers and data custodial SLAs.
