Digital twin is a simulation process that fully utilizes physical models, sensor updates, operational history, and other data, integrating multiple disciplines, physical quantities, scales, and probabilities. The MapGIS digital twin platform utilizes various sensing technologies to simulate real-world data in the digital twin world, establishing a virtual world that is identical to the real world. Relying on technologies such as big data and artificial intelligence, simulate various future events to achieve comprehensive management of space, materials, events, etc. in the past, present, and future.
