This article dea ls with the issue about the usage of airborne laser scanning materials for geodynamic moni- toring on the routes of the projected oil and gas pipelines. The purpose of this article is to demonstrate the possibility of monitor- ing of dangerous geological proce sses (DGP). The issues are solved in the article: demonstration of the monitoring concept based on airborne laser scanning, the possibility of DGP interpretation on digital topographic models and display theoretical formation of static models, the principl es of building static models in time series to obtain the dynamic models. The object of study is the conformation from the viewpoint of environment of the location of future line maintenance facilities. The resear ch subject is exogenous geological processe s, which can be dangerous for the future line maintenance facilities during operation and as a consequence provoke technogenic environmental disaster. A large amount of material in the form of digital topographi c models has a high practical value not only from the point of view of the solution of surveying problems and monitoring of exoge- nous geological processes with the status of "threat" for the construction and operation of linear structures, but also for s olving some geotechnical problems, for example decoding DGP. When considering the geodynamic monitoring on the routes of pro- jected pipelines, it is necessary to consider the fact that before you can observe a geological facility there is a need for the detec- tion and identification of its characteristic s. Building monitoring process based on data from airborne laser scanning, combined with aerial photography, it is necessary to consider methods of DGP interpretation to search for objects. Considering the fac t that airborne laser scanning enables to obtai n high - precision topographic model, the possibility of decoding according to the direct indication on the models is not possible. Therefore, it is necessary to use airborne laser scanning data, which have a direct purpose for the solution of surveying prob lems, and in solving engineering - geological problems. In this case, the methodology of monitoring based on airborne laser scanning is following: scanning area, DGP interpretation, re - scanning, analysis, etc. When using this approach, it is necessary to for m the methodology for DGP interpretation and monitoring
