Remote-sensing detection of points for the heavy vehicles crossing in the large lowland riverbeds

[摘要] The erosion-resistant culminations of the alluvial subsoil occurring in the riverbeds of some rivers may play the role of “geological bridges” under favorable hydrological conditions, constituting places convenient for forcing by heavy vehicles. The article discusses the possibility of remote-sensing identification of such places based on a common analysis of aerial images, high-resolution satellite images and Digital Terrain Models based on Airborne Laser Scanning. The result of the work was the identification of relief forms in the valley bottoms of large lowland indicating the available locations for heavy vehicles forcing the bed. This allowed for the formulation of general assumptions of the SYSTEM OF DESIGNING ZONES CONVENIENT FOR CROSSROADS USING AIR PLATFORMS.
