The article discloses the content of geotechnical monitoring, which is an information base for the diagnosis of the condition of the object and the purpose, if necessary, methods for stabilizing the situation, as well as the need for its conduct at linear objects, That is, engineering defences. The analysis of data during the geodetic work on the object «Engineering anti-landslide protection of the northern slope of the Psehako ridge» with the description of the monitoring methodology, which consists of: reconnaissance of the area, development of a network of geodetic points, Taping of the tachemetric passages, taphemeter surveys and subsequent chamber data processing, which results in a report detailing all stages of work and directly concluding that there is or is not deformation. Based on the results of the field measurements, a list of tachemetric strokes, a list of coordinates of the zero cycle were compiled. The tachemetric moves are drawn in the *dwg format at a scale of 1:500.
