CSIRO’s Data61 has developed the
NSW Spatial Digital Twin, which provides a virtual 4D (3D and time) model, currently, of Western Sydney’s built and natural environment.
The Digital Twin is an open platform that can visualise buildings, strata plans, terrain, property boundaries, utilities and sewer pipes in three dimensions over time.
The technology collects data from governments, industry, and previous digital twins and geographic systems to create an interactive live data sharing, collaboration and visualisation tool that models the urban environment.
This previously inaccessible data is federated to ensure all users are working off the same data, allowing them to effectively respond to different built and natural environments.
The platform also integrates Digital Engineering assets, Building Information Models, and live API feeds for public transport, air quality, and energy production, according to
DCS Spatial Services.
Simon Barry, acting director of Data61, said the new visualisation brings together world-leading expertise in spatial visualisation, analytics and privacy preserving technologies.
“By partnering with government and industry across the country, we can harness their technologies into a federal collaboration platform enhancing Australia’s smart cities and delivering significant benefit to Australia’s economy,” he said.
By viewing this data together, the technology helps planners, developers and policymakers to gain a broader understanding of current landscapes and the impacts of new developments on the communities, allowing them to make more informed decisions, saving costs and creating efficiencies.
“Until now, decision makers have referred to property boundaries in 2D. Having them available in 3D together with how they have changed over time, and being able to easily share this with other related data makes it much easier to fully understand the context of the boundaries,” Mats Henrikson, Geospatial Web Systems Group Leader at Data61, said.
“Cities are data rich as a result of connected sensors. This creates incredible opportunities to overlay 3D/4D data from satellite and drone technologies which is spatially accurate, to show the bigger picture of what’s happening above and below the ground,” he explained.
The technology will also enable governments to better communicate plans for infrastructure development to citizens.
Currently, the NSW Spatial Digital Twin offers an online version of Western Sydney, mapping 22 million trees with height and canopy attributes, over 500,000 buildings, 20,000km of 3D roads, 7,000 3D strata plans. This puts the visualisation of historical data alongside real-time visuals before construction begins.
Future phases of the digital twin will include other areas of Sydney visualised through the technology.
Most of the data is available to the public online, however its built-in security features ensure authorised individuals have access to certain types of data.
