What Is a Smart City Planning 3D Tool?
A smart city planning 3D tool is software or a service that enables urban planners, GIS teams, and infrastructure stakeholders to visualize, analyze, and simulate city-scale environments in three dimensions. These tools integrate diverse data sources—such as GIS, BIM, IoT, traffic, and environmental datasets—into interactive digital twins, supporting zoning analysis, infrastructure design, impact assessments, and public engagement. From procedural city modeling and scenario comparison to real-time visualization and digital twin management, the best smart city planning 3D tools help decision-makers test options and communicate outcomes clearly.
