Monument type
Villa Rustica, farm with small portico villa and outbuildings

Survey data
Area investigated: 90 m x 90 m
Resolutions: 1 MP/m2 (a = 0,56 m) : 8.100 m2 (Square)
                     1 MP/m2 (a = 0,50 m) : 8.100 m2 (Twin)
                    4 MP/m2 (a = 0,56 m) : 8.100 m2 (Twin)

Array configuration: Twin-probe and Square array
Measuring instruments: Lippmann 4point light MC
Imaging software: SURFER (Golden Software)
Survey period: 10.2018 - 11.2018

Comments
1. The square array saves carrying the trailing cable, but leads to a high level of noise due to the constantly changing position of all 4 electrodes.
2. The twin arrangement requires a trailing cable, but provides a lower level of noise due to the constantly fixed position of the two distant electrodes.
3. The fourfold resolution provides a much clearer measurement image, however, takes 3 to 4 times longer.
