“Ground-penetrating radar (GPR) methods to map and evaluate buried and architectural remains: examples from around the world” 

Dr. Lawrence B. Conyers 
Professor of Anthropology, University of Denver 



Abstract: The GPR method, which uses reflected radar waves to map the extent and composition of architectural features, can produce three-dimensional images of a variety of cultural remains where there is no surface expression of what lies below. Imaging software can take those digital readings produced from hundreds of thousands of individual reflections in high resolution grids to produce profiles, map-view slices and three-dimensional renderings of buried structures and associated cultural features. Collection, processing and interpretation of those datasets must be calibrated and modified based on the architecture of interest, but also complex ground conditions. A few of variables that must be accounted for are the frequency of radar waves transmitted, the composition and geological complexity of the ground, and the resolution and processing of the digital information collected. Examples of processing steps and analyses will be shown using a variety of visualization software at a variety of sites including a Roman villa (later modified into an early Christian cathedral) in France, Nabatean temples from Jordan, monumental architecture in Costa Rica, Aboriginal earthen constructions from northern Australia, and early colonial farmsteads from New England. 



Dr. Conyers is a professor of anthropology at the University of Denver, Colorado. He has recently published a number of books on the subject of GPR and other near-surface geophysical methods including Ground Landscape Analysis, Ground-penetrating Radar for Geoarchaeology, Ground-Penetrating Radar for Archaeology, 3 rd Editions, and Interpreting Ground-penetrating Radar for Archaeology.. His background and degrees are in the fields of geology, geophysics, and archaeology and the integration of those disciplines. He has applied this synthesis to sites around the world.
