Large scale magnetic survey and archaeological mapping. The Grosseto and Siena projects

In order to improve the quantity and above all the quality of the archaeological record, and to both sharpen and broaden the scope of our researches, we established the Laboratory of Landscape Archaeology and Remote Sensing (LAP&T). The aim of the unit is the progressive introduction of remote earth observation systems, along with the enhancement of surface collection techniques through the application of new instruments and methods of data collection and documentation, for both the archaeological and the environmental records. Though still at the stage of ‘work in progress’ we are already putting into effect a new strategy of research. This is flexible, open-ended and based on the conviction that only through the integrated application of a wide range of research methods and information technology will we be able to confront the complexities inherent in the study of the landscapes of the past (CAMPANA and FRANCOVICH 2003). Our approach is conceived as multi-scale, from the macro-environment (the region) through the local environment (the catchments area) to the point-environment (the individual site). We aim to be able to respond with varying degrees of refinement both to matters of conservation and to individual archeological or historical problems of a specifically scientific nature. So far, we have put in train the following approaches: • survey and documentation through oblique air photography; • high-resolution satellite imagery; • historical air photo coverage; • large-scale geophysical survey; • digital photogrammetry.
