Three‐dimensional ground‐penetrating radar strategies over an indoor archaeological site: Convent of Santo Domingo (Lugo, Spain)

Abstract

Abstract Indoor archaeological sites are particularly adapted for ground‐penetrating radar (GPR) surveying because the environment is uniform throughout the year. This makes them excellent for the application of meticulous three‐dimensional surveys under repeatable conditions. The objective of this work was to test different dense grid strategies and three‐dimensional imaging techniques in order to improve detection of subfloor targets. Application of the isosurface rendering technique to pseudo‐three‐dimensional volumes resulted in an efficient methodology to map the target in this particular case. This work shows a case history carried out at the convent of Santo Domingo (Lugo, Spain) where a sarcophagus was found. Copyright © 2010 John Wiley & Sons, Ltd.
