What Is a Smart City Planning 3D Solution?
A smart city planning 3D solution is a digital platform that provides an immersive, data-rich, and interactive model of an urban environment. These tools have become indispensable for urban planners, architects, and governments, allowing for complex analysis, simulation, and visualization of city-scale projects. They can range from GIS-based spatial analysis tools to comprehensive digital twins that simulate traffic, energy consumption, and environmental factors. They are widely used to design infrastructure, manage zoning, engage with the public, and make data-driven decisions to build more sustainable and efficient cities.
