Digital Twins: Thee Living Model of thee City

A digital twin is a virtual rephela that mirrors a physical asset or system in real time. Unlike a static 3D model, a twin continuously ingests sensor data andd uses simulation two conditions, predict future status, and even trigger automatic interventions. In smart city development, the twin scales from a single building to an entire metropolis.
