Abstract

APPLICATION OF PHOTOGRAMMETRIC DIGITAL ELEVATION MODELS AND AERIAL PHOTOGRAPHS IN THE RESEARCH ON THE DYNAMICS OF THE ŚLIWNICA LANDSLIDE (DYNÓW UPLAND)Abstract. This article shows the application of aerial photography and photogrammetric digital elevation models in the research on the Śliwnica landslide. The consecutive stages of the development of the Śliwnica landslide have been presented on the basis of archival aerial photographs, originating from different time periods. Twophotogrammetric high-resolution digital elevation models (DEMs) were generated and compared. This way, the dynamics of the surface of the landslide was analyzed. The differences between the grids of digital elevation models were used for determination of vertical movements of the grid points within the landslide area. The differences were visualized as a shaded relief map, with a red colour for positive elevations (erosion), and a blue one for negative ones (accumulation). The map was superimposed on digital ortophotomap dated on the October 2002. Additionally, five geomorphological cross-sections were made.
