Abstract:
This work proposes a new approach of spatial analysis, using GIS tools, in two areas of northern Tuscany (Italy): the plain of Bisenzio and Mugello. The research places seem to be a good case of study because it shows two territorial areas diversified by geomorphology and lithology, with a special attention to important actors governing site location as availability of raw material proximity and particular soils communications, at the same time analyze social actors as security and inter-visibility, and the eventual spatial and functional relationships between the different ‘settling units’. In this case, has developed a geodatabase on the GIS system composed of geomorphological, lithological and pedological maps of the areas investigated, this relational database can advance spatial query to define landscape macro-units with an integrated research. This first model of georeferenced sites can be useful for different kind of users and develop thematic maps. The second point of this work is an achievement of quantitative models of archaeological and environmental data such as viewshed analysis tool. The viewshed analysis tool measures the extent of the human range of vision from a point or cumulative points and makes a possible interaction between morphology of the landscape and settlements. The aim is to calculate the optimal locations for settlement strategies considering environmental factors of the landscape with its limit and criticality.
