Smart city is an idea to integrate technologies to support a healthy, safe, and convenient way of urban living. In the realization of smart cities, UAS can play a role in monitoring, detecting, and predicting anomalies in urban environments and therefore safeguarding humans. Because implementing real UAS experiments in urban environments is risky concerning safety and privacy, simulation may be needed to test and evaluate the performance of UAS in advance. For example, Pannozzi et al. (2019) created a simulated 3D urban environment with the aid of OpenStreetMap (OSM) volunteered geographic information for the city of Turin, Italy. The virtual city model considers wind, battery, and motor failure. Under this environment, they have successfully achieved autonomous and semi‐autonomous UAS missions using the PX4 package, and a full manual piloting flight using the Parrot‐Sphinx package. Based on their test results, they concluded UAS can be used in traffic and crowd monitoring, 3D building mapping, and urban growth to better understand urban dynamics.
