Application of Retrospective Spherical Video Documentation Technology to Collect Visual Data on the Consequences of Hazardous Coastal Processes (Based on the Example of the Taganrog Bay of the Sea of Azov)

The introduction of modern technologies contributes to the emergence of new ways to obtain visual data on the features of the transformation of sea and river banks, as well as objects of natural and anthropogenic origin located on them. The article shows the results of the development and subsequent application of technology for retrospective spherical video documentation of the consequences of hazardous coastal processes in some areas of the Sea of Azov coast. The technology is based on the use of a retrospective approach to conducting filming work in 360-degree format — panoramic video recording at certain intervals of time of the same coastal locations. The technology was tested on 13 points and sections of the coastal zone of the Taganrog Bay and the Don river delta during expeditions of the SSC of the RAS in the period from 2019 to 2023. Based on the results of experimental work 13 panoramic video retrospectives were created that show in detail the consequences of intensive manifestations of marine abrasion, landslide and river erosion processes in a period of time from several months to three years.
