Research of west Antalya landslides with sar interferometry

This study is carried out to determine the surface deformations of the landslides in the Western Mediterranean Region with the advanced InSAR techniques. In this study, radar images of Sentinel 1 satellite were processed and it is investigated the suitability of the InSAR method selected for different surface characteristics and different types of deformation. The study area covers landslides at three different locations to the west of Antalya. The data of the Interferomtric Wide Swath which is one of four imaging types of Sentinel 1 satellite is obtained from ESA's portal. The product of SLC (Single View Complex) which is SAR image will be used. Image C band λ = 5.6 cm wavelength, 5 x 20 (m) resolution, greater than 250 arrival angle, 250 km strip width image type. By Using the numerical height model from SAR image pairs of different dates to produce interferogram, ESA's "SNAP 5.0" and it's add-on "Sentinel-1 Toolbox (S1TBX) version 5.0.5" are used. In this study, which aimed to determine surface deformations by using InSAR techniques on different surface characteristics, three different regions where landslide formations were observed were selected as application area. Interferograms produced with Radar satellite imagery of landslides in the study area, which can also occur at slow and long intervals were evaluated with the landslide inventory map and field observations obtained from the General Directorate of Mineral Research and Exploration (MTA). According to the results obtained in this context, the smallest and largest displacement in the Göynük area is -0.2 to 0.16 meters.
