The aim of this paper is to image particularly buried archaeological remains with a new technique for 3D display in the Temple of Augustus (Monumentum Ancyranum) relating to the Roman time, around and in Agora in the Ulus district of Ankara, Turkey. 2D ground-penetrating radar (GPR) data were acquired on constant spaced parallel profiles in the study area. After data processing, a 3D data volume was built using a parallel 2D data set. The full data block was divided into sub-data blocks in time. A weak amplitude range was made invisible with zero opaque by applying zero opacity to these values in the visualization. The arranged visible maximum amplitude range was enlarged or the amplitude scale was weighted with a constant coefficient, which was greater than one and smaller than two and had a decimal number, according to the time range. In this way, a transparent 3D image was obtained for determining buried remains according to the depth range. Interactive visualization was carried out by constructing sub-blocks of the transparent 3D volume.
