Abstract

In general, a territory can be considered as the centre which contains all information related to different historical ages. The study of a portion of a given territory characterised by the presence of archaeological sites must be aimed at the complete and accurate acquisition of environmental data (e.g. topography, geo-morphology, litho-stratigraphy, land use, etc.), which will be used for an overall study of the site, the reconstruction of the man-environment interaction, and the evaluation of possible applications of geophysical prospecting methods. By interpreting different sets of remote-sensing data, studying existing geological and geo-morphological information and through systematic field work (e.g. archaeological survey, geophysical investigations, etc.), a wide spectrum of environmental data can be collected. The methodology of a complete analysis of the territory can be summarised as follows: analysis of remote-sensing data sets and their geo-referencing; DTM of the selected study area; morphological and geological definition of the selected study area; identification, location and geo-referencing of all archaeological sites in the territory; high-resolution integrated geophysical prospecting methods, to delineate the extension of the site and to locate the archaeological structures; a complete description of the site in its environmental context; definition of an integrated analysis method, based on the spatial correlation of the different data sets; study and design of a GIS for the management of all data sets which have been collected, elaborated and interpreted; definition of a model for the knowledge and protection of the historical and environmental aspects of the territory.
