Title: Cover surfaces as a new technique for 3D GPR image enhancement. Archaeological applications
Authors: Peña, José Antonio
Teixidó, Teresa
Issue Date: 10-Jan-2013
Abstract: Currently, there are several ways to present 3D Ground Penetrating Radar (GPR) results: time or depth slices, a mixture of radargram-slice images, GPR reflectivity maps and GPR isosurface images. In this study, we review these image-based rendering techniques and present a new alternative technique to construct 3D images that improve the visualisation of GPR results. We call this new representation technique “3D GPR cover surfaces”. To evaluate the quality of these 3D cover surfaces compared to other standard imaging techniques, we use a GPR dataset from the Iberian site of La Escuera (Alicante, Spain). These data were acquired with a 400-MHz antenna on profiles with 0.5 m spacing. We show images of the resulting 3D cover surfaces and demonstrate that they are similar to a stratigraphic archeological excavation.
Sponsorship: The GPR equipment used in this study was provided through an ERDF project (European Regional Development Fund) during 2002-2004. The GPR data used in this study were obtained at the Escuera archeological site. This site is led by Dr. Lorenzo Abad and Dr. Feliciana Sala of the Prehistory, Archeology, and Ancient History Department of the Alicante University (Spain).
