Petroleum industry techniques yield new insights into 3D GPR data

We have adapted petroleum industry technologies to 3D GPR datasets from a variety of geological and archaeological settings. Seismic attribute analysis designed for 3D seismic volumes of oil fields has been used to map a 19th century cemetery and to prepare a Roman archaeological site for detailed study by mapping the prior disturbances of the site. Specific seismic attributes that we have successfully applied include connectedness (“geoanomalies”), semblance (or dissimilarity), volume rendering (transparency visualization), and waveform classification. An especially powerful strategy is to use two or more attributes simultaneously via volume rendering that allows multiple visualizations.
