What Is a Virtual City Planning Model?
A virtual city planning model is a digital, often 3D, representation of an urban environment used for analysis, simulation, and visualization. These models have become indispensable tools for urban planners, architects, governments, and developers. They range from data-rich Geographic Information Systems (GIS) and Building Information Modeling (BIM) platforms to immersive, real-time simulations. Their primary purpose is to help stakeholders understand complex urban systems, test development scenarios, assess environmental and social impacts, and engage the public in the planning process before any physical construction begins.
