Abstract:
The authors consider the application of geoinformation mapping in the analysis of hazardous processes using space images, digital terrain models, as well as comparative analysis of the landscape map and the map of hazardous exogenous processes. As a result, a large-scale map of hazardous processes within the Mondy depression was created. At the first stage, space images, physical and geographical conditions were analyzed, as well as the morphometric indicators of the territory. On the basis of that analysis classes of hazardous exogenous processes that affected the landscapes of the depression were identified. Further the classes of hazardous exogenous processes were compared with landscape facies, within the contours of which hazardous processes of different intensity are common. Calculation of hazardous exogenous processes using the data of morphometric indicators was made, the information on the long-term change in the main elements of the climate of the study area obtained. The method of spatial analysis in geographic information systems on a vector basis marked the main hazardous exogenous processes that have developed in the territory of the Mondy depression. The gravitational-slope class, represented by collapses and screes, is most widespread in the investigated area. Fluvial class of the dangerous exogenous processes is mostly indicated by mudflows in the valleys of small and temporary watercourses. Cryogenic class of these processes is least developed.
