PREHISTORIC SETTLEMENT PATTERNS IN BOHEMIA

A means of detecting features which lie below the ground surface, based on the measurement of electrical resistivity and the identification of magnetic anomalies. The Institute of Archaeology has its own, high-power equipment of this type - including two caesium magnetometers. With the aid of this equipment, measurements are taken at various kinds of site, although most attention is devoted to features of a linear character (enclosures) discovered by aerial prospection.
