Identifying of buried archaeological remains with ground penetrating radar, polarized microscope and confocal Raman spectroscopy methods in ancient city of Nysa, Aydin - Turkey

Two-dimensional (2D) GPR data were measured on parallel GPR profiles using 250 MHz shielded antennas for selected areas of the ancient city. A processed GPR profile data set formed a solid 3D view by aligning the profiles. An interactive interpretation of depth slices, 2D and 3D subsets of the data were performed. The depth slices and the subsets clearly imaged the remains of walls and streets. Slices with different amplitude-colour ranges and cutoff values were compared. The compared slices showed that amplitude-colour range and cutoff value affected the imaging indicating buried remains. Finally, three streets were determined with 3D depth slices and their 3D subsets using the GPR data. Two streets were on the west part of the gerontikon (council building), aligned east-west and north-south. The third street was aligned east-west on the southwest part of the gerontikon. Partial excavations of the northwestern and southwestern parts of the research area encouraged the 3D image results exactly.
