An increasing number of Australian states government departments and local councils are using or are in the process of acquiring virtual 3D city models as part of their planning and development strategy. In addition to other geospatial information layers integrated into interactive 3D GIS solutions such as Skyline TerraExplorer, these new tools provide intuitive and innovative ways to communicate complex information and develop long-term management strategies.

Traditional virtual 3D city models are often simplified individual objects where other smaller assets (such as street furniture, trees, cars, footpaths) are missing or added manually. Photogrammetric 3D city models such as this aero3Dpro model of Townsville provide a robust base dataset where every modelled asset is a close representation of the reality; this is particularly true for trees.
These intelligent virtual city environments based on 3D models generated from 3D photogrammetry provide:
- Tools for planners and developers to perform accurate analysis on the impact of new developments (taking into account other objects such as trees). Sight lines can be checked to make sure neighbour’s privacy are respected. Sun and shade analysis can be applied to simulate the impact of the shade on the surrounding area.
- Tools for emergency services and law enforcement such as immersive simulation, hazard assessments, flood modelling, planning/response coordination, trafficability, line of sight (for example surveillance camera optimal location), telecommunication coverage, building ingress/egress.
- Visually appealing and clear way to communicate information to all stakeholders including the public and non-technical decision makers. In addition to non-interactive and interactive fly-through, augmented and virtual reality technologies also provide new communication mechanisms.
- New ways to extract and show information by improving the convergence between geospatial and non-geospatial disciplines and fusing data.

These information-rich 3D environments provide accessible virtual platforms to improve the way decisions are made and complex information are extracted and communicated.
