Abstract

This paper aims to describe the settlement dynamics in the province of Teramo, in the Abruzzo region, along the coastal area between the Tronto and the Vomano rivers, in the Norman Age. Starting from the study of 26 sites, relevant to both towers and medieval fortifications, the objective is to construct a GIS probability map for the presence of five other sites that are mentioned in various historic documents but have now disappeared. Analysing some variables linked to the territory and exploiting the spatial distributions of the existing sites, in particular in relation to the sea and the rivers, it is possible to obtain useful data for prediction. More precisely we have considered: 1) the viewshed analysis, 2) the distances from the sea, 3) the distances from the rivers, 4) the distances among the existing sites, 5) the slope, 6) the aspect and 7) the distance from the toponym of the uncertain locations. Linear combination of the raster representing these variables lead to a final map, which contains different values of plausibility related to the presence of a dubious site. The weights of the linear combination are provided by an expert using the pairwise comparison technique, through a multicriteria approach.
