The article presents the possibilities of using unmanned aerial vehicles (UAV) in engineering geology. The first part compares the method of obtaining products from UAV with airborne laser scanning, showing its limitations and advantages. Then, examples of using the products made from photos obtained from UA V raids (digital surface model - DSM, digital terrain model - DTM and orthophotomosaic) were introduced. The examples are assigned to the individual phases of engineering geology documentation (collecting available information about the site, designing research, performing research and presenting research results). The last part presents an analysis of the accuracy of an exemplary model created from a UAV raid based on control points measured using the GNSS-RTN method. The result of the analysis was the confirmation of the possibility of obtaining information about the area from the DSM, DTM and orthophotomosaic with high accuracy comparable to classic land surveying methods.
