3D City Model
The City of Adelaide has created a digital 3D City Model that is helping visualise the City’s future, particularly in relation to growth scenarios and land use planning
|SWOT Analysis for
3D City Model
|Strengths• Available for public access: Ability to walk and fly through the Model and be fully immersed in the virtual City. The entire 3D City Model (excluding digital terrain data) can be downloaded free-of-charge and with no restrictions on its use from the State Government’s Data SA website. The models are in .3DS format with JPEG textures
• Accuracy of terrain: locations and buildings within the Model are generally within 50cm accuracy.
|Weaknesses• Downloading significant amounts of data and the responsiveness will depend on the speed of internet connection.
• The data usage may also have implications on internet plan’s download usage, and limit restrictions.
|Opportunities• Provide a public consultation tool to assist in visualising transport, urban design and planning.
• Provide architects and building designers with 3D model data to assist in developing and refining their building proposals in a simulated real-world environment.
• Assist in assessment of development applications for new buildings, enabling accurate overshadowing, overlooking and simulation of how the building will look within the City context.
• Illustrating the location of heritage sites and (in the future) other important public facilities and attractions, linking in with photos and text information.
• Collaborating with government agencies and other bodies in visualising future transport, urban design and infrastructure projects.
• 3D city models prove to be quite suitable for the handling and visualization of 3D spatial information, have a very broad spectrum of needs, values and uses in diverse areas such as urban planning, virtual reality, tourism, property management, maintenance of infrastructure infrastructures, disaster management, among others. These models offer a true and real image of the planet earth as much as possible, which allows planners / engineers / architects visualize all aspects of easy and objective way, and even the ability to archive, manage, and analyse large amounts of information either at the building level, as the level of urban space.
|Threats• Limitations on personal privacy and anonymity
• Unauthorised access to georeferenced building information
• It is not unambiguous what Level of Detail (LOD) is in 3D city modelling
• There is not a single and widely-accepted LOD paradigm in 3D city modelling. There are no general guidelines and it is not clear what drives the LOD
• Mixed-scale / perspective-view in 3D city modelling is not researched.
