Abstract
Information on the movements and stress-strain state of the Earth`s surface and crust is necessary to predict catastrophic geodynamic processes, such as earthquakes, volcanic eruptions, landslides, glacier collapses, karst sinkholes and subsidence of soils in mining areas. The authors summarize the existing experience of applying geoinformation technologies for modeling Earth’s surface deformations; reveal the shortcomings of current software solutions and the approach to their joint use for analyzing these processes. The relevance of using spatial data infrastructure as a source of data on Earth`s surface deformations is noted. Solutions for improvement of Earth`s surface deformations imaging with the help of the three-dimensional vector fields visualization method, presented by the authors in previous surveys, as well as the results of visualization of the Earth`s surface displacements model, demonstrating applicability and operability of the method developed by the authors, are offered. The requirements and the general functional layout of the thematic geographic information system intended for geoinformation modeling of the Earth`s surface deformations and administrative tasks solution are formed.
