What Is 3D Modeling for Urban Planning?
3D modeling for urban planning is the use of specialized software to create digital representations of urban environments. It's a critical tool that goes far beyond creating simple visuals; it's about integrating complex datasets like GIS, zoning codes, and demographic information to analyze development scenarios, conduct environmental studies (like shadow or viewshed analysis), and facilitate informed decision-making. This technology allows planners, stakeholders, and the public to visualize and understand proposed changes at a city or regional scale, making it indispensable for modern master planning, infrastructure projects, and public engagement.
