AB: Ground surface geophysical prospecting methods have been used as valuable techniques for non-invasive detection of shallow-depth bodies of archaeological interest. Generally the often limited size and depth of the archaeological remains, the presence of structures made with the same material as the host rocks, soil inhomogeneity and the environmental and anthropogenic disturbances, make it rather difficult to define the position and the extension because of the low signal-to-noise ratio (S/N). Multi-methodological surveys have been employed with the aim of detecting either sharp discontinuities (boundary of the cavity, fractures in the medium, etc) or volumetric variations (bodies with different physical properties), at different archaeological test sites. For the surveys a combination of passive and active methods (magnetic, GPR and dipole-dipole geoelectric method) has been employed. The aim of the present work is to demonstrate the advantages of integrating the results obtained using different geophysical methods. The Fluxgate Differential Magnetic (FDM), the Ground Penetrating Radar (GPR) and the Dipole-dipole Geoelectric (DDG) methods and their results, used to investigate different archaeological sites, have been integrated. With all methods a high resolution data acquisition method has been adopted with the aim of reconstructing a global vision of the investigated area. The enhancement of the processing technique towards the integration of different geophysical methods, enabling one better to define the location, depth and geometry of any archaeological bodies, has been adopted.
