Enhancement of 2D/3D GPR Data Imaging by the Proposed TAEF Technique: Displaying Archeological Remains under the Colonnade Road in Anavarza Ancient City, Adana, Turkey

Abstract

Summary Ground Penetrating Radar (GPR) is a geophysical method that is used for investigating and visualizing the underground structures. The GPR usage has been increasing recently, because it can determine and visualized underground structures sensitively without any excavation. The aim of this study is to enhance 2D/3D GPR data imaging quality with the proposed methodology and visualize the buried archaeological remains under the archaeological road called as “Colonnade Road” in Anavarza ancient city, in Adana, Turkey. In this context, a new threshold and enhancement filtering technique has been proposed to contribute to reduce the effect of the environmental noise and physical or chemical changes of the soil in the defined study area. The proposed methodology consists of three stages. The first stage is the GPR data collection and processing. The second stage is calculating a proposed threshold and an enhancement value. The final stage is obtaining a final GPR profile data sections by adding the enhancement value and visualizing them in 3D GPR data volume obtained by sequencing of them. The results have been showed that the anomalies more visible and distributed from its environment on the quality enhanced GPR sections and their x-y time/depth slice of their 3D GPR data volume.
