summary	City digital twins are becoming increasingly important for the sustainable development of cities, and augmented reality (AR) has been attracting attention as a tool for visualizing city digital twins. In addition, from the perspective of SDG 11, it is essential to manage flood risk in urban spaces. However, there are no case studies that present a bird‚s-eye view of a simulated city. Visualizing the state of a flooded city during a disaster is one potential use case. From the perspective of information graphics, people want to understand urban data at the micro and macro levels. This study proposes a city-digital-twin approach for visualizing a simulated city using a large-scale AR and drone integration method that does not require a specific software development kit (SDK). This system can visualize the state of a city flooded by a disaster from both a bird‚s-eye view of the city at several tens of metres above it and from a first-person perspective of the user‚s area of activity. The applicability of the system is demonstrated through verification and case studies.
