1 Integration between different remote-sensing surveys to characterise Aiali archaeological site (Grosseto, Central Italy)

To enhance the knowledge of the Aiali site (Grosseto, Central Italy), finalised to the location and conservation of the unknown buried structures below the actual studied levels, a scientific collaboration between Landscape Archaeology, Department of Archaeology and History of Arts, (LAP&T), Università di Siena a Grosseto and the Institute of Technologies Applied to Cultural Heritage (ITABC-C.N.R.) has been developed, during the time 2005-2006 and it is still in progress (Campana et al, 2006a). The site has been studied analysing a set of vertical aerial photographs and making aerial surveys from 2002 to 2004, with the aim to locate buried structures. Together with these information, a large scale geophysical surveys, employing a differential magnetic method and a GPR survey, have been carried out between 2004 and 2006. Integrated Remote sensing surveys As usually we started working on the oldest available aerial photograph, that in this case is the national coverage of 1954. Unfortunately any feature was visible on the historical flight because the site was used for olives cultivation. Nevertheless the soil use changed to grai
