Analysis and classification of actual geodetic methods for studying the quantitative parameters of earth surface deformations

The aim of the work is to analyze and evaluate current methods for studying Earth’s surface subsidence-dip deformation processes of technogenically impacted areas and to classify these methods. The analysis of existed methods for studying the spatio-temporal changes in the Earth’s surface consists in their critical assessment based on studied literary sources and highlighting advantages and disadvantages of the geodetic methods for studying the deformation processes of hazardous territories (with landslides and failures). Applying the classification method, a scheme of geodetic methods used in the Earth’s surface monitoring of technogenically loaded areas was developed. The analysis and evaluation of actual geodetic methods for studying the quantitative parameters of subsidence-dip deformation processes has been carried out. Literary sources written by Ukrainian and foreign scientists are processed. The advantages and disadvantages of the studied methods are presented. The classification of geodetic methods for studying and monitoring Earth’s surface deformations has been developed. The obtained results can serve as a theoretical basis that allows for further improvement of the technology for studying subsidence-dip deformation processes of technogenically impacted territories in order to predict technogenic disasters, improve the environmental situation and ensure life safety. The presented classification structures the current geodetic methods of studying the quantitative parameters of the spatio-temporal changes of the Earth’s surface.
