Uno strumento GIS per indagare il paesaggio agro-pastorale dell'Etruria Meridionale.

In this paper I will illustrate the function of an ArcGIS’s tool developed to carry out a series of landscape archeology’s raster analyzes in the contexts considered. Thanks to this tool, it is possible to quickly and immediately analyze both the primary economy of the settlements and the resulting socio-organizational forms, also verifying their functioning from the point of view of demographic sustainability. The work of the tool is simple and completely automated. In fact, once the center of the settlement to be analyzed is indicated, the system autonomously defines: 1) the size of the area exploited according to the bubble method; 2) the dimension of pastures and cultivated areas; 3) the relative food yields produced by these. Finally, through the yields of animal and vegetable origin, 4) hypoth- esizes the maximum number of people who could be supported by this exploita- tion of the territory
