Impiego del Differential Global Positioning System (DGPS) per lo studio del paesaggio antico: alcuni esempi rappresentativi

In recent years, the use of DGPS (Digital Ground Positioning System) satellite antennas has become widespread within the framework of the historical-topographic research. They give us the possibility of geo-referencing, in a very easy way, different objects spread across the territory, and permit the delimitation and geometrical survey of specific areas rendered in the shape of polygons. In the present project, new case-studies, aimed at defining new procedures for geo-referencing of territorial elements, are produced. In these case-studies the use of DGPS, employed in a new and integrated way with other modern topographical instruments, has enabled us to survey complex structures and to produce detailed morphological studies of the sites. The archaeological sites that have been examined show great differences; first, in their geomorphologic characteristics, the historical period, the cultural environment and related problems and second, for the different scale of the research, procedures and level of investigation of the archaeological research.
