Survey of the Outline of an Early Roman Marching-camp in Germany by Rammner's Current Line Pertubation Method

The outline of the first discovered early Roman Marching-camp north of the Limes in Germany (Dorlar, State of Hessen) was determined by electrical resistivity sounding. The camp was inhabited sometime between 11 and 15 and used as base to conquer Dünsberg, a keltic-germanic oppidum. Rammner's Current Line Pertubation Method (CLP) detected soil disturbances caused by ancient Roman construction. The CLP-Method was used to measure the perturbation of a current due to inhomogeneities in the ground. Data processing made it possible to determine the outline of the Roman marching-camp with an accuracy of ±0·15 m. The electrical soundings were confirmed by selected excavations.
