A digital twin of Darwin to monitor and navigate change
The Digital Twin uses high-resolution (10 cm) data of the distribution, area, and height of urban vegetation (e.g., trees, shrubs and grass); impervious surfaces (e.g., buildings, roads); and bare ground and water to map the condition of Darwin’s landscape in 2011, 2016, and 2021. This is being used to analyse change in tree canopy cover. Also, the information, coupled with local tree inventory data about species composition and condition, was used to quantify and value the stocks and flows of ecosystem services provided by urban trees. The valuation of services is based on the international System of Environmental and Economic Accounting (SEEA) framework.
