Electrical Resistivity and Ground Penetrating Radar Surveys at Wiang Tha Kan Archaeological Site, Chiang Mai Province, Northern Thailand

Abstract

Summary The GPR surveys were employed to detect an extended ancient wall at Wat Pra Chao Kam area located northeast of Wiang Tha Kan Archaeological Site. Some parts of the ancient wall has been excavated and the extended wall has been presumed to exist. The GPR surveys covered areas connected to the exposed wall. GPR anomaly maps at various depths show a linear anomalous zone connected to the exposed wall at 0.4–0.8 m depth. This zone may be interpreted as a location of the buried ancient wall. The GPR maps is useful for planning of future archaeological excavation.
