Ultimately, all of these actions have disrupted maritime traffic. These restrictions also included ports, shipping and sea voyages, disrupting the movement of passengers, crew and preventing ships from entering ports. During the quarantine period, many countries imposed restrictions. Iran's geographical location has also been surrounded by the busiest seas from the north and south, as about 30% of the world's maritime transport takes place in the Persian Gulf. For this reason, the monitoring of maritime traffic in any country is of great importance. Sea transportation is one of the oldest methods of transportation that is used today to transport goods and passengers to other parts of the country, regionally and internationally. In Europe, the European Space Agency has also paid attention to the Covid-19 epidemic in reducing air pollution and its indirect effects on the environment. In Europe, the European Space Agency has also considered the Covid-19 epidemic in reducing air pollution and its indirect effects on the environment. To prevent the spread of Covid disease, many countries imposed restrictions on communities and travel. The outbreak of coronary heart disease (Covid-19) began in late 2019 in Wuhan, China, and later spread worldwide. In general, this study demonstrates the role of using satellite data, especially artificial aperture radar images, in marine applications and global crisis management, as well as the rapid processing of high-volume radar data in the Google Earth Engine cloud. But with the normalization of the corona situation and the resumption of maritime activities again in 2021, maritime traffic and traffic has increased as in the pre-corona period. The results of this study showed that traffic and maritime traffic in the two study areas of the Strait of Hormuz and Bandar Pol in April and May 2020 compared to the same month in 20 has a significant decrease, which has a direct impact on the shipping industry. These images were processed in the Google Earth Engine cloud environment to identify and extract marine vehicles, including ships. In line with the objectives of this research, VV polarization of Sentinel-1 radar images in C band was used. The purpose of this study is to monitor maritime traffic in the Strategic and International Strait of Hormuz and the port of Pol during the Corona outbreak.
Maritime navigation is one of the main commercial and economic activities. Background and Objectives: The global corona outbreak has had a direct impact on many navigation activities around the world.
