The problem of flooding with the thawed waters of the Esil River is an extremely important task and requires special attention, since the late evacuation of the population can lead to death. In recent years, there has been a spill of the Esil River before the expected date, which causes damage to human settlements and damage to agriculture, subsequently increasing financial losses. There is a need to develop new methods for studying the terrain in flooded areas, so that these methods allow us to see a more accurate picture of the alleged flooding before the onset of an emergency situation, with the possibility of preventing the consequences of: human, financial, agricultural losses. For a more accurate forecasting, the use of Agisoft PhotoScan, GIS Sputnik software is proposed to build detailed altitudinal mapping of flood zones with the melting waters of the Esil River.
