Monitoring of Hazardous Geotechnical Processes Using the Geoinformation Systems and Earth Remote Sensing Data

The paper deals with the issues of remote monitoring of karst, erosion, and flooding processes in the area of line-ar construction design using remote sensing data, in particular, the high-resolution space and multispectral Senti-nel-2 images. The use of multi-temporal high-resolution space images makes it possible to assess the dynamics of surface karst development and to monitor the development of flooding zones. Calculation of spectral indices for the purpose of raster image binarization and selection of water objects masks allows to automate the selection of flooding zones and to estimate their sizes. Instrumental analysis of digital elevation model by means of geo-graphic information systems (GIS) is an accessible and effective method for assessing the intensity of the erosion process, allowing clarifying the zoning of the territory with regard to karst hazard. Complex analysis of hydro-logical, geomorphological and geological conditions using remote sensing data and GIS tools is informative for studying engineering and geological processes in the areas of their development.
