The article presents an integrated approach to processing field geological survey data using GIS technologies. Integrated images from unmanned aerial vehicles (including multispectral), lidar scanning data. Highly detailed orthophotographs, digital relief models, and 3D models of the area under study were obtained, reflecting the complex structure of the outcrops. It is shown that the combined processing of photogrammetric, multispectral, and lidar data improves the accuracy of detecting geological structures compared with the disparate use of methods. The scientific novelty of the work is the application of an integrated approach to obtaining geospatial data based on a combination of aerial photography, lidar technologies and ground–based laser scanning andthe development of a single method for integrating heterogeneous data for geological mapping. The results can be used in the search for deposits of rare metals, engineering and geological surveys and monitoring of hazardous processes.
