From acoustics to underwater archaeology: Deep investigation of a shallow lake using high‐resolution hydroacoustics—The case of Lake Lednica, Poland

One of the main challenges underwater archaeology is to develop non-invasive research heritage sites in order enable their further protection for future societies. This study explores, identifies and classifies archaeological objects a shallow lake using acoustics. We solved aforementioned by developing an innovative, object-based, fuzzy-logic classification nine object categories based on multibeam echosounder bathymetry, 13 secondary features bathymetry 106 diving prospections. achieved 86% correlation with ground-truth samples, 49% overall accuracy. The unique repeatable workflow developed this can be applied other case studies around world.
