The establishment of digital twins to improve urban governance is a consensus in many countries, the COVID-19 epidemic has catalysed the digital transformation.
Digital twin combines 3D modelling with geographic information system (GIS), alongside smart sensors, big data, artificial intelligence to connect the real city with its duplicated virtual version to facilitate analysis and monitoring of city operations. In addition, various hypotheses, such as solar radiation time frame, privacy issues, flooding risks, potential conflicts with existing buildings, can be imposed for viewing with 360-degree imagery. By analysing the big data of the virtual city, one can attempt to predict natural disasters or accidents and take necessary precautionary measures. It also enables the authority to have a clearer understanding of the effects of a development plan before it is implemented, so that the plan can be revised in time to improve governance…….
