Automation of digital elevation model analyzing when solving problems of economic development of karst territories

The combination of geographic information systems (GIS) and remote sensing data analysis tools will make it possible to assess in a short time and with high accuracy the suitability of an area for the construction of land or linear structures in the areas where dangerous geological processes are developed. In this article we use the example of karst area in Kisherstky district of Perm region as an example to carry out the karts hazard zoning of the territory according to geomorphological indicators by analyzing ALOS-DEM digital elevation model (DEM). Patterns in the distribution of karst forms in the study area were evaluated depending on the dissection of the relief, its slope and distance from the watercourses. Based on the patterns, an integral map was constructed. The approach allows to do zoning the territory with respect to the studied danger geological process in a short time and with high accuracy, which is due to the use of patterns of forms distribution in the analysis.
