Vertical displacement monitoring technique using radar interferometry data

Abstract

All phenomena and processes occurring on the Earth's surface are closely related. Earth is characterized by internal and external planetary geological processes, which, throughout the entire geological development of the Earth, lead to its change. The speed and scale of geological processes change in time and space due to climatic changes. Changes are divided into long-term and momentary ones, which cause catastrophic phenomena, including landslides. An essential component of geoecological research is monitoring landslide processes using data from remote sensing of the Earth. The possibility of remote geoecological monitoring of landslide processes using satellite radar interferometry has been investigated, tested and experimentally substantiated. The right bank of the Kaniv Reservoir, with many registered landslides, was chosen as the test site. The results of the activity of vertical displacements of landslides for the spring period from 2015 to 2023 were obtained. Nine test sites and five control, stable areas affected by active surface deformations were investigated using 45 Sentinel-1A images. Geoecological monitoring of the activation of landslide processes at a detailed level was carried out using Sentinel-1 satellite images, a digital terrain model (DEM), topographic maps of various scales, and geological maps of Quaternary and pre-Quaternary structures. The advantage of the study of landslide processes by remote methods is the ability to quickly, on large areas, with relatively high accuracy and minimal economic costs, solve the problems of environmental protection to ensure the sustainable development of the environment and society.
