Cüneyt and Zirek, İrfan}, keywords={Heyelan, İHA, GPS/GNSS, Fotogrametri, SYM, SAM}, abstract={In this study, the principles, analyzes and results of landslide monitoring are presented by using aerial photographs obtained with the help of high-resolution cameras integrated with unmanned aerial vehicles. For this purpose, active landslide near Sarıcaeli Village, pilot study area, was selected. This landslide has been tried to be modeled using unmanned aerial vehicle photogrammetry and global positioning system. In this context, data were collected from the field for three periods, in May 2016, September 2016 and January 2017. These obtained data were evaluated during a series of photogrammetric workflows and final products such as digital surface models, digital terrain models, three-dimensional models and orthomosaics were produced. In addition, these products were processed in the geographic information system and the temporal development of the landslide was analyzed.}, number={5}, publisher={Çanakkale Onsekiz Mart Üniversitesi}
