Ground Penetrating Radar Trace Shape Classification Using Self Organizing Maps – An Example from Ancient Aptera, Greece

In this paper we propose and apply a GPR trace shape classification technique, for imaging a Roman cistern in the ancient city of Aptera in Greece. We classify the trace shape of reflected waves from the roof of a Roman cistern. The classification is based on an artificial neural network namely, Self Organizing Maps (SOM). The same technique classifies reflected and diffracted waves from metal and plastic pipes buried in a sandbox.
