GPR and Geophysical Archaeometry

With advances in imaging software, the utility of ground penetrating radar (GPR) as a remote sensing tool for archaeological discovery has been greatly enhanced. Software has been the key to extracting subsurface information contained in (noisy) raw radargrams. Traditional time slice analysis, isosurface rendering, and "overlay analysis" are among several image analyses used to identify buried archaeology. Static corrections are developed for the first time which account for the tilt of GPR antenna at sites with topography. With the recent introduction of GPR-GPS surveying to facilitate and automate remote sensing, the accuracy in the 3D imaging of unmarked grave sites has been improved. Successful examples of GPR imaging and time/depth animations for the discovery of Roman sites, the internal design of Japanese tumulus mounds, and Native American Indian tribal grounds are shown
