The solution of multiscale tasks on monitoring and hazard assessment of slope processes can be reasonably and promptly carried out only with the help of remote sensing means of high and ultra-high spatial and temporal resolution, turned operational maps and services. An effective methodological approach for monitoring, early warning, risk and consequence assessment of exogenous processes manifestations is operational geoinformation modeling, which relies on cartographic method and satellite technologies. Use of space images of high and ultrahigh spatial resolution for solving some tasks is practically impossible, such as detection of rockfalls and individual rockfalls. Only the use of aerial photography from manned or unmanned aerial vehicles can give proper results. Technical features of UAVs allow to consider this type of survey as an alternative to sub-satellite observations, carried out from manned vehicles, or to airborne interpretation. When conducting geomorphological research based on aerial survey data, digital elevation models are built and exogenous processes of relief formation are monitored. The main results of the research were the following projects: - highly detailed digital elevation and terrain models for different stages of process manifestation; - derived high-detail morphometric models for automated extraction and forecasting of the processes development; - large-scale zoning of the territory by degree; - scientifically substantiated and spatially differentiated scenarios of operational response for the territories of settlements and transport infrastructure objects in the zone of high risk of extreme exogenous processes; - multiscale interactive web-mapping application for monitoring the development of dangerous geomorphological processes.
