The relevance of the work is due to the need to improve the methods for monitoring engineering structures of oil and gas transport in sparsely populated and hard-to-reach regions. To ensure the safe operation of pipeline systems, it is proposed to use remote sensing data to establish both the spatial position of the object and the activation centers of undesirable geological processes (karst, solifluction, landslide processes, etc.). As the main factor influencing the activation of such processes, it is definitely worth noting the tectonic disturbances of the territory. The research aimed at detecting and extracting special tectonic structures – lineaments – is today an important analytical method for finding relationships between the geodynamics of a territory and various geological processes. Purpose of the work – identification of lineaments and compilation of a general picture of tectonic activity along the pipeline route to assess their impact on the activation of karst sinkholes. Research methods. The main focus is on the construction and extraction of lineaments from a digital elevation model using the tools of the PCI Geomatica and ArcGis programs with their subsequent verification. In addition to construction, visual and analytical numerical data are presented to determine the relationship between the parameters of tectonic fracturing and karst manifestations. Results. The article presents the results of the influence of tectonics on karst manifestations within the route of an oil pipeline located in difficult engineering-geological and cryological conditions in southern Yakutia. Detailed maps of tectonic activity and distribution of lineaments in the study area have been developed, compiled on the basis of engineering-geological materials and decoding of digital elevation models (satellite images). The obtained results of the density of the general tectonic jointing showed a close connection with the previously discovered karst manifestations within the route. Conclusions. The application of an integrated approach to the consideration of geodynamic activity makes it possible to improve approaches to the description and study of territories that are complex in terms of engineering and geological parameters. Lineament-geodynamic analysis proves the need to consider tectonic fracturing as the main factor influencing karst activation.
