“…2, W(x) frequency spectra obtained using the developed remote methods [5,6,14] and those obtained in situ agree well. The degree of coincidence between these spectra obtained using W sat (x) satellite and W cont (x) in situ data is estimated by the measure of the deviation [6].…”

“…For example, when assessing the adequacy of developed methods for wave spectra retrieval using satellite imagery spectra [5,6,14], sea surface slope and elevation spectra obtained through high-resolution satellite image processing were compared with wave spectra measured by a string wave meter array and through stereo photography from a hydrophysical platform [6]. Figure 2 shows the example results of comparing sea wave spectra retrieved from GEOEYE image fragment processing, obtained by a string wave meter array, and with Toba approximation [28].…”

In this paper, we describe the developed methods and technologies, as well as the created research prototype of a ground-space regional monitoring system that was used for comprehensive experimental research of anthropogenic impact on Russian Black sea coastal water areas. Changes in significant water environment parameters (generation of additional spectral components of surface waves; changes in marine surface roughness affecting normalized radar cross-section; turbidity field anomalies affecting spectral brightness variations in various bands of electromagnetic spectrum, etc.) registered in satellite imagery of water areas under anthropogenic impact were revealed. It has been established that these effects were predominantly caused by deep wastewater discharges. Zones of anthropogenic pollution propagations, as well as pipe breakages, have been revealed. The validation of the obtained satellite imagery processing results has been conducted based on sea truth data carried out using buoys, as well as from boats and hydrophysical platform.

High-performance methods are described for recording the spectra of the sea surface from space images for solving problems of operational oceanography. Algorithms have been developed that implement methods for quickly reconstructing the characteristics of the atmosphere-hydrosphere interface using satellite imagery and research software for quickly reconstructing the characteristics of the sea surface from satellite imagery. The developed algorithms were tested and their performance was estimated using experimental data. The developed prototype of research software is designed to work with the use of multi-core processors. The program performs the restoration of the spectra of slopes and elevations of the sea surface using the developed high-performance methods. The performed computational experiments showed the feasibility of increasing the productivity of recording the spectra of slopes and elevations of the sea surface from the spectra of space images due to parallelization of calculations.

The article presents methodological approaches to assessing the expected socio-economic effect of reducing the resource potential of the tourism business in conditions of increased possibility of natural and artificial emergencies. The research aims to use Earth remote sensing technologies in recreational areas with subsequent socio-economic analysis to reduce the resource potential in the tourism business in the context of the deteriorating ecology of the territories. The work uses regression analysis, methods for deciphering satellite images using various techniques, mathematical modelling and the formation of forecasts using regression models. A general methodology is proposed for constructing a geo-ecological model using information generated from data from space, Earth remote sensing technologies, and monitoring territories for waste sites with a socio-economic justification for tourism business in recreational areas. A mathematical model for the formation of tourist flows using remote sensing technologies has been developed, as well as a methodology for forecasting tourist flows using PLS and PLS-LM methods.
