Any comprehensive interpretation of GPR data must include the integration and analysis of both amplitude slice-maps and two-dimensional reflection profiles. Often one method can yield results that the other cannot, producing important insights. One example from Ireland shows how slice-maps produced very useful images of subtle post molds, which outlined a crannog in a pond…

A GPR program was conducted on a hilltop on the island of Brač, Croatia to assess whether this area was a fort, or a defensive structure, as had been suggested by people for many years. Its location, the sight-lines from the ridgetop, and the surface artifacts all supported this idea perhaps dating from the Bronze…

Many GPR reflection profiles were collected using a canoe on a freshwater lake in the Rocky Mountains. Excellent radar wave penetration was measured, using both 270 and 400 MHz antennas. Reflection traces were placed into space using GPS and individual profiles were interpreted, with the lake bottom and other reflections digitized for three-dimensional mapping. It…
