Abstract

USE OF AERIAL IMAGES IN RESEARCH OF MASS MOVEMENTS – A CASE STUDY OF THE LACHOWICE LANDSLIDE (WESTERN CARPATHIANS, BESKID MAKOWSKI MTS)Abstract. The article presents the application of photogrammetric digital elevation models in the study of the Lachowice landslide. For this purpose, aerial photos taken in 1977, 2003, 2009 have been used. Digital terrain models (DTM) have been produced from the point cloud generated on the aerial images, using images matching. Generated models allowed calculating the volume of displaced rock masses. Zones of loss and accumulation of rock masses have also been identified. The presence of identifiable points on all images enabled the determination of the values and directions of horizontal displacement vectors.
