'MetaVu_MetaCity' is a comprehensive spatial information platform service that utilizes digital twin technology to create virtual representations of real-world spaces and supports their management and prediction. While traditional digital twin technology has been limited to industrial equipment and multi-bus platforms, 'MetaVu_MetaCity' expands the scope from equipment to workspaces and from workspaces to cities, gradually enabling the 3D visualization of information and data for cities and buildings that have been traditionally managed using 2D data such as maps and construction drawings. Furthermore, it allows users to manage various desired information more intuitively and facilitates diverse simulations without physical constraints in a realistic environment. It can be applied in various fields such as ensuring safety, system improvement, and data collection.
