3D City Model (Digital Twin)

A virtual 3D city model is a digital model of urban and rural areas. It represents terrain surfaces, buildings, vegetation, infrastructure and other objects belonging to an urban space.

This technique can be used to spatially design and visualise development. It can also be used to compare different urban design strategies. These can be evaluated against measures such as land use, building height, floor area ratio, population and housing densities, as well as development costs.

Planners can use 3D modelling to analyse and communicate the impact of both existing and new (re)development plans. They can look, for example, at overshadowing, sunlight exposure, view corridors, compliance with zoning regulation, traffic gravity and solar potential of buildings.

The 3D models also offer a new platform to involve citizens in urban planning. It’s a way for Council to ensure that public concerns, values and aspirations are informing decisions.

Challenge/Opportunity Solution Key benefits
Improved development processes Accessible 3D model of the City Developers and engineers have free access to a digital model of the City including building dimensions, pits and underground pipes. This significantly reduces time, cost and effort involved.
Better visualisation of new development Utilise 3D models and VR technology  3D makes it easy for anyone to view and comment on plans without special skills, enabling the City to gain richer feedback from community and other stakeholders.


Clever creative outcomes
