Monitoring of mining branches according to satellite radar interferometry
Authors M. Pakshyn, I. Liaska, K. Burak, L. Dorosh and M. HrynishakSummaryThese studies are aimed at establishing the current capabilities of radar interferometry methods and the prospects of their use for observations of vertical deformations on the example of the mine field Khotin Kalush-Golinsky field. The comparative study of PS and SBAS radar data processing methods justifies the use of radar interferometry technology to analyze the dynamics of deformation processes of the earth's surface and near-surface objects. Over a short period of time, these methods make it possible to analyze the deformation of the earth's surface. Features of PS and SBAS methods are analyzed. To verify the results of these methods, measurements of shear values in the most problematic areas were observed by high-precision geometric leveling with a short beam. The results of observations by ground (geometric leveling with a short beam) and space (radar interferometry) methods correlate and confirm the presence of a zone of active sedimentation in the mining area.

Determination of quantitative indicators of earthquake destruction by different time space images
Authors B. Chetverikov, I. Trevoho, L. Babiy, Kh. Marusazh and R. AbdallahSummaryThroughout history, natural disasters have constantly plagued humanity, the greatest damage was caused by earthquakes, taking many lives, destroying cities and infrastructure. Determining the results of an earthquake, namely damages and destructions of buildings is one of the main needs in dealing with the consequences of a natural disaster. Recently, natural disasters caused by anthropogenic phenomena have increased in the world. Therefore, the scientific study of the destructions caused by cataclysms of natural origin is an extremely important problem. Involvement of digital photogrammetry and geoinformation technologies is very effective in this matter. The area that has been destroyed on a large scale on the Earth's surface needs to be determined with the help of satellite images and remote sensing data. The main purpose of the work is the processing of digital satellite images obtained from the GeoEye-1 satellite on 15.07.2017 and 18.11.2017, in order to identify areas affected by the earthquake on the border of Iraq and Iran. Namely, part of the city of Sarpol-e Zahabb, located in Iran. When performing the work, a comparison of the automatic and manual methods was used. During the experimental studies, photogrammetric, cartographic methods and methods of remote sensing of the Earth were used. The work was performed using the Erdas Imagine software and he Delta CUE module. The technique of determining the difference indicators of the earthquake consequences by the automatic method is described. The results of the work can be used to calculate losses after natural disasters. As the results of detecting the area of damaged objects due to the earthquake it was found in automatic mode that 61 objects were damaged, and the total area of damage is 19103m2, the area of the largest object is 3300m2.
